The Grivet Arm (1978) by Gallaher Research Inc., Western-Salem, North Carolina.

"Purchasing some form of "experimenter's arm" kit? There has been one attempt at a commercial kit product for the robot arm experimenter, a product which was advertised in this magazine starting last spring. I refer to the Gallaher Research "Grivet" arm, which is shown in photo 1. The photograph was taken using the kit I bought for $400 and put together one Sunday morning in September. … Mr Gallaher's robot arm was a crude start at best, for all we got is a rather shaky mechanism with six DC motors. The purchaser's inventiveness must supply the details of electronic interface and control. A suggestion, in the marketing literature supplied with the kit, is that relays be used to provide control of the 6V DC which will run the motors. This kit provided what you see in the photograph: a limited mechanical start on a complete arm which must include a mounting of some sort, power supplies, bidirectional motor drive electronics, and sensory feedback. There is not even a suggestion of how to mount and use sensors to provide feedback control of the arm in a practical object manipulation environment such as a chessboard with chess pieces as the objects.

The designer of this arm did his homework with respect to balance, for it will sit upright on its counterweight with no particular urge to topple over. The photograph was taken with the arm in this position. But if mounted in a horizontal position as suggested by the sales literature (assembly drawings, but no instruction manual, come with this device) several of the parts are under enough stress to be visibly bent. The only way I can see to practically mount this arm is by having it hang down from the shaft furthest from the hand mechanism (flipping it 180 degrees around the vertical axis of photo 1).

The Gallaher arm kit's parts are apparently handcrafted. When you think of the time and energy that went into its creation, it is obviously a bargain at $400, even if incomplete. Some of the first microcomputer kits such as the Mark-8, Altair and Sphere were similarly incomplete, and a whole industry was formed filling in the gaps to provide a complete computer system in assembled form. Therefore, we can expect more complete robotic systems as further products are offered to the experimenter. Just as "hardheaded realists" (ie: unimaginative people) scoffed only four years ago at the idea of a personal computer, I can almost hear the equivalent comments about domestic robots being uttered as I pen these words at the keyboard of my personal computer." – Byte Magazine February 1979, Volume 04 Number 02 (p6).

STRANGE DAYS (1995) KALIFORNIA (1993) *JULIETTE LEWIS

These two double feature films I am presenting today owes it to Juliette Lewis images on my reblog random rampage selection by a Tumblr blogger actress-playground who has been posthumously deleted.

Strange Days is a 1995 American science fiction thriller film directed by Kathryn Bigelow, from a screenplay by James Cameron and Jay Cocks, and based on a story by Cameron.

Juliette Lewis (22) in Strange Days (1995)

The movie blends science fiction with film noir conventions, Strange Days explores themes such as racism, abuse of power, rape and voyeurism. Although the story was conceived by Cameron around 1986, Bigelow found inspiration from high profile incidents such as the Lorena Bobbitt incident and the 1992 Los Angeles riots.

The film was a major commercial failure, Strange Days nearly derailed Bigelow's career. The film polarized critics upon release, while some praised the cinematography, visual style, and performances of the cast, others criticized its portrayal of rape and violence. Its critical standing has improved over the years, gaining a cult following. At the 22nd Saturn Awards, where the film received five nominations, Bassett won Best Actress and Bigelow became the first woman to win Best Director.

Upon release, Strange Days polarized film critics. Roger Ebert, who gave the film four out of four stars, described it as "a technical tour de force" and highlighted the film's astute use of SQUID technology, stating that "Bigelow is able to exploit the idea of what is happening; she forces her audience to deal with the screen reality, instead of allowing us to process it as routine 'action.'"

Set in Los Angeles on the last two days of 1999, the film follows Lenny Nero (Fiennes), a black marketeer of an electronic device that allows a user to experience the recorded memories and physical sensations of other people, and Lornette "Mace" Mason (Bassett), a bodyguard and limousine driver, as they are drawn into a criminal conspiracy involving Nero's ex-girlfriend Faith Justin (Lewis) and the murder of a prostitute.

Kalifornia is a 1993 American road thriller film directed by Dominic Sena, in his feature film directorial debut.

The movie was filmed in Georgia and rural inland California.in the spring of 1992. The movies was a box office bomb. The film received mixed reviews from critics with some praising its art house sensibility, while others dismissed it as a violent exploitation film. Despite this, the film's acting was largely praised, and critic Roger Ebert heralded the performances of Pitt and Lewis among the best he had ever seen. The film was nominated for three Saturn Awards in 1994, including for Best Horror Film.

The film tells the story of a journalist (Duchovny) and his photographer girlfriend (Forbes) traveling cross-country to research serial killings, who unwittingly carpool with a psychopath (Pitt) and his childlike girlfriend (Lewis).

Imagining The New Panem after the deconstruction and reconstruction of the Government Post Books:

• Imagining Panem keeps the general Name/Districts + Capital system, just with some changes. The New Government opens borders and makes Panem a more joyfully Unified nation and a pretty cool place! They encourage relocation and more cross-district industry.

• The Districts and Capital relatively remain the same, and in the same places, but a lot of them restructure a bit. This is how I see that:

The Capital:

The Capital is one place I see changing a bit. They change from the Governmental ruler to being a place devoted to being Panem’s genuinely trusted News Source. It becomes a District of Ambassadorship, and Rebuilding Panem’s Culture into something healthy. The Capital’s former ‘Culture’ of just Dictatorship and Money and Body Modification becomes a Culture devoted to Improving the lives of its Citizens and taking pride in having so much Diversity. It becomes a place devoted to celebrating advancement in Culture, Fashion, Technology, Education, Agriculture and Environmental efforts, and so on. They also begin to develop a new, healthier entertainment industry.

District One: Luxury to Economy

D-1 completely reorganizes from a place of greed and superficial luxury to becoming essentially Panem’s Bank/Wall Street/Stock Market. They also become responsible for creating a trade route between the districts. They’re where the districts send the products they make, and they distribute them to the people and Companies throughout Panem who buy them.

District Two: Masonry (and Construction)

D-2 reworks its industry into being the Construction Headquarters of Panem. They’re responsible for LITERALLY REBUILDING PANEM. They lose the Defense responsibilities, but still make the weapons. They make All of the Weapons and industrial Tools used in Panem.

District Three: Electronics/echnology

D-3 shifts from being a Factory for The Capital’s toys to becoming a Hub for Technological advancement. With a bit of freedom, and a healthier culture, I can see D-3 shooting Panem SO FAR INTO THE FUTURE IT’S INSANE.

District Four: Fishing, Seafood, Ocean, Marine Science.

D-4 expands its duties to becoming a place of Seafood Culture, Beach Life, and its government is in charge of Panem’s Navy. I see it becoming home to Marine Science centers and Aquariums and general coastal life.

District Five: Power and Electrticity

D-5’s duties are also similar to before the Revolution, but it becomes a more ethical system. They also become devoted to clean energy for All of Panem.

District Six: Transportation

Ok so admittedly we don’t get much about D-6 except that they make the Trains and Cars for the Capital..

So.

I think after the Revolution D-6 becomes responsible for developing Panem’s new Inter-district transportation system. A unified sky railway system throughout all of Panem that is Solar Powered and ends up being the best thing to ever happen to Panem. They also work on getting Solar Powered Cars into all of the districts.

District Seven: Lumber

D-7 becomes closely knit with D-2 and they basically head the efforts to Physically Rebuild Panem. They basically just shift to having a more open industry.

District Eight: Textiles

Instead of being yet another Capital Sweat Shop, D-8 becomes a more ethically run place with a better industry. It becomes a place of Fashion culture and Textile factories.

District Nine: Grain

D-9 also remains largely the same but joins in Panem’s new Industry.

District Ten: Livestock

D-10 works with D-1, and D9 to create a new network of Grocery Markets across Panem and generally becomes a better place.

District Eleven: Agriculture

D-11 becomes a much MUCH less oppressed place. They develop a more mutually beneficial and less Government controlled Agricultural system.

District Twelve: Coal (but also Medical?)

Ok so HEAR ME OUT. D-12 is rebuilt, the mines never to reopen, and takes charge of Panem’s Medical Research. They have Apothecaries that supply all of Panem with Medicine after they Reconstruct. I imagine Panem’s medical industry to be very natural remedies meets a little bit of technology. I have a headcannon that before the first war D-12 WAS actually in charge of medicine, but I have zero proof other than the Apothecary Katniss’s mom runs and Prim being a Doctor.

District Thirteen: Government, Law, Space, and Nuclear Research

District Thirteen has a MASSIVE rebuild, becoming a Multi-Level, Multi-industry district.

I imagine they rebuild above ground to become the face of their Nation Wide, normal Government stuff. Laws, Elections, important jobs.

But I also think they keep their Military, and Nuclear research in some of their Underground facilities. I also think D-13 becomes the home of Panem’s Space Research Program kind of like Nasa.

And I also think they are in charge of the new Peace Keeping forces. Of course most of that is FBI level facilities who are in charger of smaller, more classic government programs in the other districts. Those programs are more important than the ones in charge of them though honestly.

J.4.7 What about the communications revolution?

Another important factor working in favour of anarchists is the existence of a sophisticated global communications network and a high degree of education and literacy among the populations of the core industrialised nations. Together these two developments make possible nearly instantaneous sharing and public dissemination of information by members of various progressive and radical movements all over the globe — a phenomenon that tends to reduce the effectiveness of repression by central authorities. The electronic-media and personal-computer revolutions also make it more difficult for elitist groups to maintain their previous monopolies of knowledge. Copy-left software and text, user-generated and shared content, file-sharing, all show that information, and its users, reaches its full potential when it is free. In short, the advent of the Information Age is potentially extremely subversive.

The very existence of the Internet provides anarchists with a powerful argument that decentralised structures can function effectively in a highly complex world. For the net has no centralised headquarters and is not subject to regulation by any centralised regulatory agency, yet it still manages to function effectively. Moreover, the net is also an effective way of anarchists and other radicals to communicate their ideas to others, share knowledge, work on common projects and co-ordinate activities and social struggle. By using the Internet, radicals can make their ideas accessible to people who otherwise would not come across anarchist ideas. In addition, and far more important than anarchists putting their ideas across, the fact is that the net allows everyone with access to express themselves freely, to communicate with others and get access (by visiting webpages and joining mailing lists and newsgroups) and give access (by creating webpages and joining in with on-line arguments) to new ideas and viewpoints. This is very anarchistic as it allows people to express themselves and start to consider new ideas, ideas which may change how they think and act.

Obviously we are aware that the vast majority of people in the world do not have access to telephones, never mind computers, but computer access is increasing in many countries, making it available, via work, libraries, schools, universities, and so on to more and more working class people.

Of course there is no denying that the implications of improved communications and information technology are ambiguous, implying Big Brother as well the ability of progressive and radical movements to organise. However, the point is only that the information revolution in combination with the other social developments could (but will not necessarily) contribute to a social paradigm shift. Obviously such a shift will not happen automatically. Indeed, it will not happen at all unless there is strong resistance to governmental and corporate attempts to limit public access to information, technology (e.g. encryption programs), censor peoples’ communications and use of electronic media and track them on-line.

This use of the Internet and computers to spread the anarchist message is ironic. The rapid improvement in price-performance ratios of computers, software, and other technology today is often used to validate the faith in free market capitalism but that requires a monumental failure of historical memory as not just the Internet but also the computer represents a spectacular success of public investment. As late as the 1970s and early 1980s, according to Kenneth Flamm’s Creating the Computer, the federal government was paying for 40 percent of all computer-related research and 60 to 75 percent of basic research. Even such modern-seeming gadgets as video terminals, the light pen, the drawing tablet, and the mouse evolved from Pentagon-sponsored research in the 1950s, 1960s and 1970s. Even software was not without state influence, with databases having their root in US Air Force and Atomic Energy Commission projects, artificial intelligence in military contracts back in the 1950s and airline reservation systems in 1950s air-defence systems. More than half of IBM’s Research and Development budget came from government contracts in the 1950s and 1960s.

The motivation was national security, but the result has been the creation of comparative advantage in information technology for the United States that private firms have happily exploited and extended. When the returns were uncertain and difficult to capture, private firms were unwilling to invest, and government played the decisive role. And not for want of trying, for key players in the military first tried to convince businesses and investment bankers that a new and potentially profitable business opportunity was presenting itself, but they did not succeed and it was only when the market expanded and the returns were more definite that the government receded. While the risks and development costs were socialised, the gains were privatised. All of which make claims that the market would have done it anyway highly unlikely.

Looking beyond state aid to the computer industry we discover a “do-it-yourself�� (and so self-managed) culture which was essential to its development. The first personal computer, for example, was invented by amateurs who wanted their own cheap machines. The existence of a “gift” economy among these amateurs and hobbyists was a necessary precondition for the development of PCs. Without this free sharing of information and knowledge, the development of computers would have been hindered and so socialistic relations between developers and within the working environment created the necessary conditions for the computer revolution. If this community had been marked by commercial relations, the chances are the necessary breakthroughs and knowledge would have remained monopolised by a few companies or individuals, so hindering the industry as a whole.

Encouragingly, this socialistic “gift economy” is still at the heart of computer/software development and the Internet. For example, the Free Software Foundation has developed the General Public Licence (GPL). GPL, also know as

“copyleft”, uses copyright to ensure that software remains free. Copyleft ensures that a piece of software is made available to everyone to use and modify as they desire. The only restriction is that any used or modified copyleft material must remain under copyleft, ensuring that others have the same rights as you did when you used the original code. It creates a commons which anyone may add to, but no one may subtract from. Placing software under GPL means that every contributor is assured that she, and all other uses, will be able to run, modify and redistribute the code indefinitely. Unlike commercial software, copyleft code ensures an increasing knowledge base from which individuals can draw from and, equally as important, contribute to. In this way everyone benefits as code can be improved by everyone, unlike commercial code.

Many will think that this essentially anarchistic system would be a failure. In fact, code developed in this way is far more reliable and sturdy than commercial software. Linux, for example, is a far superior operating system than DOS precisely because it draws on the collective experience, skill and knowledge of thousands of developers. Apache, the most popular web-server, is another freeware product and is acknowledged as the best available. The same can be said of other key web-technologies (most obviously PHP) and projects (Wikipedia springs to mind, although that project while based on co-operative and free activity is owned by a few people who have ultimate control). While non-anarchists may be surprised, anarchists are not. Mutual aid and co-operation are beneficial in the evolution of life, why not in the evolution of software? For anarchists, this “gift economy” at the heart of the communications revolution is an important development. It shows both the superiority of common development as well as the walls built against innovation and decent products by property systems. We hope that such an economy will spread increasingly into the “real” world.

Another example of co-operation being aided by new technologies is Netwar. This refers to the use of the Internet by autonomous groups and social movements to co-ordinate action to influence and change society and fight government or business policy. This use of the Internet has steadily grown over the years, with a Rand corporation researcher, David Ronfeldt, arguing that this has become an important and powerful force (Rand is, and has been since its creation in 1948, a private appendage of the military industrial complex). In other words, activism and activists’ power and influence has been fuelled by the advent of the information revolution. Through computer and communication networks, especially via the Internet, grassroots campaigns have flourished, and the most importantly, government elites have taken notice.

Ronfeldt specialises in issues of national security, especially in the areas of Latin American and the impact of new informational technologies. Ronfeldt and another colleague coined the term

“netwar” in a Rand document entitled “Cyberwar is Coming!”. Ronfeldt’s work became a source of discussion on the Internet in mid-March 1995 when Pacific News Service correspondent Joel Simon wrote an article about Ronfeldt’s opinions on the influence of netwars on the political situation in Mexico after the Zapatista uprising. According to Simon, Ronfeldt holds that the work of social activists on the Internet has had a large influence — helping to co-ordinate the large demonstrations in Mexico City in support of the Zapatistas and the proliferation of EZLN communiqués across the world via computer networks. These actions, Ronfeldt argues, have allowed a network of groups that oppose the Mexican Government to muster an international response, often within hours of actions by it. In effect, this has forced the Mexican government to maintain the facade of negotiations with the EZLN and has on many occasions, actually stopped the army from just going in to Chiapas and brutally massacring the Zapatistas.

Given that Ronfeldt was an employee of the Rand Corporation his comments indicate that the U.S. government and its military and intelligence wings are very interested in what the Left is doing on the Internet. Given that they would not be interested in this if it were not effective, we can say that this use of the “Information Super-Highway” is a positive example of the use of technology in ways un-planned of by those who initially developed it (let us not forget that the Internet was originally funded by the U.S. government and military). While the internet is being hyped as the next big marketplace, it is being subverted by activists — an example of anarchistic trends within society worrying the powers that be.

A good example of this powerful tool is the incredible speed and range at which information travels the Internet about events concerning Mexico and the Zapatistas. When Alexander Cockburn wrote an article exposing a Chase Manhattan Bank memo about Chiapas and the Zapatistas in Counterpunch, only a small number of people read it because it is only a newsletter with a limited readership. The memo, written by Riordan Roett, argued that “the [Mexican] government will need to eliminate the Zapatistas to demonstrate their effective control of the national territory and of security policy”. In other words, if the Mexican government wants investment from Chase, it would have to crush the Zapatistas. This information was relatively ineffective when just confined to print but when it was uploaded to the Internet, it suddenly reached a very large number of people. These people in turn co-ordinated protests against the U.S and Mexican governments and especially Chase Manhattan. Chase was eventually forced to attempt to distance itself from the Roett memo that it commissioned. Since then net-activism has grown.

Ronfeldt’s research and opinion should be flattering for the Left. He is basically arguing that the efforts of activists on computers not only has been very effective (or at least has that potential), but more importantly, argues that the only way to counter this work is to follow the lead of social activists. Activists should understand the important implications of Ronfeldt’s work: government elites are not only watching these actions (big surprise) but are also attempting to work against them. Thus Netwars and copyleft are good examples of anarchistic trends within society, using communications technology as a means of co-ordinating activity across the world in a libertarian fashion for libertarian goals.

So I made an app for PROTO. Written in Kotlin and runs on Android.

Next, I want to upgrade it with a controller mode. It should work so so I simply plug a wired xbox controller into my phone with a USB OTG adaptor… and bam, the phone does all the complex wireless communication and is a battery. Meaning that besides the controller, you only need the app and… any phone. Which anyone is rather likely to have Done.

Now THAT is convenient!

( Warning, the rest of the post turned into... a few rants. ) Why Android? Well I dislike Android less than IOS

So it is it better to be crawling in front of the alter of "We are making the apocalypse happen" Google than "5 Chinese child workers died while you read this" Apple?

Not much…

I really should which over to a better open source Linux distribution… But I do not have the willpower to research which one... So on Android I stay.

Kotlin is meant to be "Java, but better/more modern/More functional programming style" (Everyone realized a few years back that the 100% Object oriented programming paradigme is stupid as hell. And we already knew that about the functional programming paradigme. The best is a mix of everything, each used when it is the best option.) And for the most part, it succeeds. Java/Kotlin compiles its code down to "bytecode", which is essentially assembler but for the Java virtual machine. The virtual machine then runs the program. Like how javascript have the browser run it instead of compiling it to the specific machine your want it to run on… It makes them easy to port…

Except in the case of Kotlin on Android... there is not a snowflakes chance in hell that you can take your entire codebase and just run it on another linux distribution, Windows or IOS…

So... you do it for the performance right? The upside of compiling directly to the machine is that it does not waste power on middle management layers… This is why C and C++ are so fast!

Except… Android is… Clunky… It relies on design ideas that require EVERY SINGLE PROGRAM AND APP ON YOUR PHONE to behave nicely (Lots of "This system only works if every single app uses it sparingly and do not screw each-other over" paradigms .). And many distributions from Motorola like mine for example comes with software YOUR ARE NOT ALLOWED TO UNINSTALL... meaning that software on your phone is ALWAYS behaving badly. Because not a single person actually owns an Android phone. You own a brick of electronics that is worthless without its OS, and google does not sell that to you or even gift it to you. You are renting it for free, forever. Same with Motorola which added a few extra modifications onto Googles Android and then gave it to me.

That way, google does not have to give any rights to its costumers. So I cannot completely control what my phone does. Because it is not my phone. It is Googles phone.

That I am allowed to use. By the good graces of our corporate god emperors

"Moose stares blankly into space trying to stop being permanently angry at hoe everyone is choosing to run the world"

… Ok that turned dark… Anywho. TLDR There is a better option for 95% of apps (Which is "A GUI that interfaces with a database") "Just write a single HTML document with internal CSS and Javascript" Usually simpler, MUCH easier and smaller… And now your app works on any computer with a browser. Meaning all of them…

I made a GUI for my parents recently that works exactly like that. Soo this post:

It was frankly a mistake of me to learn Kotlin… Even more so since It is a… awful language… Clearly good ideas then ruined by marketing department people yelling "SUPPORT EVERYTHING! AND USE ALL THE BUZZWORD TECHNOLOGY! Like… If your language FORCES you to use exceptions for normal runtime behavior "Stares at CancellationException"... dear god that is horrible...

Made EVEN WORSE by being a really complicated way to re-invent the GOTO expression… You know... The thing every programmer is taught will eat your feet if you ever think about using it because it is SO dangerous, and SO bad form to use it? Yeah. It is that, hidden is a COMPLEATLY WRONG WAY to use exceptions…

goodie… I swear to Christ, every page or two of my Kotlin notes have me ranting how I learned how something works, and that it is terrible... Blaaa. But anyway now that I know it, I try to keep it fresh in my mind and use it from time to time. Might as well. It IS possible to run certain things more effective than a web page, and you can work much more directly with the file system. It is... hard-ish to get a webpage to "load" a file automatically... But believe me, it is good that this is the case.

Anywho. How does the app work and what is the next version going to do?

PROTO is meant to be a platform I test OTHER systems on, so he is optimized for simplicity. So how you control him is sending a HTTP 1.1 message of type Text/Plain… (This is a VERY fancy sounding way of saying "A string" in network speak). The string is 6 comma separated numbers. Linear movement XYZ and angular movement XYZ.

The app is simply 5 buttons that each sends a HTTP PUT request with fixed values. Specifically 0.5/-0.5 meter/second linear (Drive back or forward) 0.2/-0.2 radians/second angular (Turn right or turn left) Or all 0 for stop

(Yes, I just formatted normal text as code to make it more readable... I think I might be more infected by programming so much than I thought...)

Aaaaaanywho. That must be enough ranting. Time to make the app

#PROTO #codeblr #programming #Softeware #Kotlin #Kotlin is.... so bad....

The Future of Lithium Batteries: Trends and Innovations in 2025

As we move further into 2025, the future of lithium batteries looks more promising than ever. With the rise of electric vehicles (EVs), renewable energy solutions, and portable electronics, lithium-ion batteries have become a fundamental technology that powers much of our modern world. However, as the demand for energy storage solutions increases, so too does the pressure to improve the efficiency, sustainability, and safety of these batteries.

In this blog, we will explore some of the most exciting trends and innovations shaping the future of lithium batteries, from advancements in solid-state technology to efforts aimed at making battery production more sustainable.

1. Solid-State Batteries: A Revolutionary Shift

One of the most exciting developments in battery technology is the progress being made in solid-state batteries (SSBs). These batteries promise to outperform traditional lithium-ion batteries in almost every category, offering higher energy densities, greater safety, and longer lifespans.

Traditional lithium-ion batteries use a liquid electrolyte to transfer ions between the cathode and anode, which is both a limitation and a potential safety risk. In contrast, solid-state batteries use a solid electrolyte, which reduces the risk of leakage, thermal runaway, and fires. Solid-state batteries are also expected to offer a higher energy density, which means they can store more energy in a smaller, lighter package — a game changer for industries like electric vehicles (EVs) and consumer electronics.

While solid-state batteries are still in the research and development phase, they are expected to become commercially viable within the next few years. Major companies like Toyota, BMW, and QuantumScape are already making strides in this area, with promising results from prototype batteries.

2. Lithium-Sulfur and Lithium-Air Batteries: Pushing the Boundaries of Energy Density

While lithium-ion technology has been the dominant player for over a decade, alternative chemistries like lithium-sulfur (Li-S) and lithium-air (Li-Air) batteries are gaining significant attention due to their potential for even higher energy densities.

Lithium-Sulfur Batteries: These batteries use sulfur as the cathode material, which is both abundant and cheap. They also have a theoretical energy density several times higher than conventional lithium-ion batteries, making them ideal for electric vehicles and long-duration energy storage. However, challenges with cycle life and efficiency remain, but breakthroughs in materials science could bring lithium-sulfur batteries to market in the near future.

Lithium-Air Batteries: These batteries use oxygen from the air as the cathode material, which could theoretically provide an even greater energy density than lithium-sulfur. Lithium-air batteries could potentially offer the same energy capacity as gasoline, which would revolutionize electric vehicles. However, challenges with stability, efficiency, and practical implementation still need to be overcome before they can become viable for widespread use.

3. Battery Recycling and Sustainability

As demand for lithium-ion batteries continues to grow, so too does the need for sustainable practices. Mining for lithium, cobalt, and other key materials for battery production has raised significant environmental concerns, especially in regions where these resources are mined under poor labor conditions and with little regard for environmental impacts.

To combat these issues, there is a growing focus on improving battery recycling technologies. Companies are now developing more efficient ways to extract valuable materials like lithium, cobalt, and nickel from used batteries, which will help reduce the demand for new mining operations.

One promising development is the rise of closed-loop recycling systems, where used batteries are collected, broken down, and the materials reused in new batteries. This not only reduces waste but also minimizes the carbon footprint associated with raw material extraction. In 2025, we expect to see more investment in scalable recycling technologies, especially as governments worldwide push for greater sustainability in the energy storage sector.

4. Battery Manufacturing Innovations

The future of lithium batteries is not just about the chemistry inside the cells — it’s also about how these batteries are manufactured. Innovations in production techniques are helping to lower the cost of lithium batteries and improve their performance.

Automated Production Lines: Companies are increasingly using advanced robotics and AI-driven manufacturing processes to improve the efficiency and scalability of battery production. This allows for higher consistency and reduced production costs, which will ultimately make electric vehicles and other battery-powered products more affordable for consumers.

Solid-State Manufacturing: With solid-state batteries on the horizon, new manufacturing processes will be required to handle the unique materials and fabrication techniques involved. Researchers are developing new methods to create these batteries at scale, ensuring that they can eventually be produced at a competitive price point.

3D Printing: Another breakthrough that could impact battery manufacturing is the use of 3D printing technology. Researchers are exploring ways to 3D-print battery components, potentially allowing for more precise designs and more efficient manufacturing methods. This could lead to faster production times and lower costs for both lithium-ion and solid-state batteries.

5. Faster Charging Times and Longer Battery Life

In 2025, one of the most anticipated improvements in lithium batteries is the ability to charge faster without sacrificing battery life. Researchers are working on developing new anode and cathode materials that can support faster electron movement, thereby enabling faster charging times. Additionally, improvements in battery management systems are helping to balance the charge and discharge cycles more effectively, extending the overall lifespan of batteries.

This trend is particularly important for electric vehicles, where charging time has long been a barrier to widespread adoption. Faster-charging batteries will make it more convenient for drivers to use EVs for long trips, reducing range anxiety and making EVs a more practical alternative to gasoline-powered vehicles.

6. Energy Storage for the Grid

Beyond electric vehicles and portable electronics, lithium-ion batteries are also playing an increasingly important role in the energy sector. With the rise of renewable energy sources like solar and wind, there is a growing need for large-scale energy storage systems to balance supply and demand. Lithium-ion batteries are well-suited to this task, as they can store excess energy generated during peak production times and release it when demand is high.

As energy grids continue to evolve, we are likely to see more investment in grid-scale energy storage projects, helping to ensure the stability and reliability of renewable energy sources.

7. AI and IoT Integration for Battery Management

In the future, the integration of artificial intelligence (AI) and the Internet of Things (IoT) with battery management systems (BMS) will further optimize battery performance. AI algorithms can predict battery behavior, such as charging patterns and degradation rates, allowing for more efficient energy use and longer battery life. In the case of electric vehicles, this could lead to smarter charging systems that automatically adjust charging speed based on battery health and external factors like temperature.

The IoT aspect could also allow batteries to communicate with other devices, ensuring optimal performance in real-time. For example, a connected electric vehicle could sync with a nearby charging station, enabling faster and more efficient charging by adjusting settings according to the battery's needs.

Conclusion

The future of lithium batteries in 2025 is filled with incredible innovations and opportunities. From the development of solid-state and alternative lithium-based chemistries to advancements in manufacturing, recycling, and sustainability, we are on the brink of a new era in battery technology. These advancements will not only help power the next generation of electric vehicles and consumer electronics but also play a crucial role in advancing renewable energy solutions and making our world more sustainable. As these technologies evolve, we can look forward to a future where batteries are safer, more efficient, and more environmentally friendly than ever before.

US Tech Stocks Stabilize After DeepSeek AI App Disrupts Market

US tech stocks held steady on Tuesday after experiencing a sharp decline on Monday, triggered by the unexpected rise of the Chinese-made artificial intelligence (AI) app, DeepSeek.

Shares of chip giant Nvidia, which had fallen sharply on Monday, rebounded by 8.8% as experts suggested the AI market selloff may have been an overreaction. Investors were quick to adjust their positions after DeepSeek claimed its AI model was developed at a fraction of the cost of its competitors' offerings.

The news sparked concerns over the future of America's AI dominance and raised questions about the scale of investments US companies are planning. US President Donald Trump described the situation as "a wake-up call" for the tech industry, while also suggesting that the development could ultimately be beneficial for the US economy. He remarked that if AI models could be produced more cheaply while delivering the same results, it would be a positive outcome for the country.

Trump downplayed concerns, emphasizing that the US would remain a key player in the AI field. The surge of optimism around AI investments has fueled much of the US stock market's growth over the past two years, prompting fears of a potential market bubble.

DeepSeek, launched just a week ago, quickly became the most downloaded free app in the US. Its rise comes amid ongoing tensions between the US and China over AI technology, with the US restricting the export of advanced AI chips to China.

Chinese AI developers, facing limited access to these chips, have shared research and explored alternative approaches that demand less computational power. This has led to the creation of AI models that are significantly cheaper to produce, challenging industry norms and threatening to disrupt the market.

Nvidia, the leading provider of advanced chips used in many AI applications, was hit hardest by the market selloff. Its share price dropped 17% on Monday, erasing nearly $600 billion from its market value.

Analysts, including Janet Mui of RBC Brewin Dolphin, explained that investors typically respond with caution to groundbreaking developments due to uncertainty. However, she noted that the cheaper AI models could benefit tech giants such as Apple and other firms, who have faced scrutiny over their high AI investments.

After the initial shock, US stock markets stabilized on Tuesday. The Dow Jones Industrial Average rose 0.3%, the S&P 500 gained nearly 1%, and the Nasdaq saw a 2% increase. In the UK, the FTSE 100 closed 0.35% higher. Meanwhile, AI-related stocks in Japan, including Advantest, SoftBank, and Tokyo Electron, saw sharp declines, contributing to a 1.4% drop in the Nikkei 225. Several Asian markets remained closed for the Lunar New Year holiday, with mainland China's markets set to reopen on February 5.

DeepSeek's Founder: Liang Wenfeng

DeepSeek was founded in 2023 by Liang Wenfeng in Hangzhou, China. The 40-year-old, an engineering graduate, also established the hedge fund that financed the development of the AI app. Liang recently attended a meeting with industry leaders and Chinese Premier Li Qiang. In a July 2024 interview, he expressed surprise at the sensitivity surrounding the pricing of his AI models, stating that the company had simply focused on cost-efficient development and pricing without anticipating such a reaction from the market.
