Researchers develop membrane technology for sustainable lithium extraction

- By Nuadox Crew -

Imperial College London researchers have developed a membrane technology that efficiently extracts lithium from saltwater sources like salt-lake brines and geothermal solutions, offering a sustainable alternative to traditional mining.

Conventional lithium extraction is slow, water-intensive, and polluting, but the new approach, led by Dr. Qilei Song, uses special polymers with micropores that selectively filter lithium while blocking contaminants like magnesium. 

Tested successfully on simulated brines, the membranes produce high-purity, battery-grade lithium carbonate and can be scaled up using existing industrial methods.

Imperial has filed patents and is working on commercializing the technology, which has broader applications in energy storage, water purification, and metal recovery.

Lithium-ion Batteries from Drones Might Find Second Lives in Less ‘Stressful’ Devices - Technology Org

Lithium-ion Batteries from Drones Might Find Second Lives in Less ‘Stressful’ Devices - Technology Org

Taking flight can be stressful — especially for a lithium-ion battery that powers a drone. Too much strain on these cells causes damage and shortens a device’s lifespan.

Research in ACS Energy Letters shows the potential to improve batteries in aerial electric vehicles that take off and land vertically. The team developed a new electrolyte to address these challenges and said the “stressed out” batteries could also have second lives in less strenuous applications.

Lithium-ion batteries (LiBs) have exploded in popularity thanks to their ability to pack a large amount of power in a relatively small, light package. But they aren’t perfect, especially when a lot of that power needs to be drawn from the battery cell quickly.

For example, drones put a high strain on their batteries during takeoff. While hobby drones traditionally use lithium-ion polymer batteries instead of LiBs, the latter’s high energy density is better suited for heavier-duty drones, such as those that deliver cargo to remote locations. To better understand how high-strain events like liftoff can affect LiB stability, Ilias Belharouak, Marm Dixit and colleagues “stressed out” a set of LiBs and investigated how their performance changed.

The researchers manufactured a set of LiB cells containing a specially designed, fast-charging and discharging electrolyte. Then, they drained 15 times the battery’s optimal capacity, the total amount of energy it could store, for 45 seconds. This process simulated the rapid, high-power draw, also known as a discharge, needed during vertical takeoff.

After the initial discharge pulse, the cells were further drained at a more normal discharge rate and then recharged. The team found that none of the tested cells lasted more than 100 cycles under these high-stress conditions, with most starting to show decreased performance around 85 cycles.

After being “stressed,” the researchers subjected the LiB cells to a more normal, lower rate power draw. In this experiment, they observed that the cells partially retained their capacities under low-rate conditions, but failed quickly when put under rapid current drain conditions again.

These results indicate that the LiBs typically used in drones might not have the characteristics necessary for long-term, high-stress usages, but they could be retired and meet more typical power demands in other applications, such as battery back-ups for power supplies and energy-grid storage. The researchers say that more work is needed to develop alternative battery technologies that are better suited for vertical takeoff and other high-power-demand applications.

Researchers develop polyurea membranes for lithium recovery from waste batteries

In a study published in the Journal of Membrane Science, a research group led by Prof. Wan Yinhua from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences propose a new zone-regulated interfacial polymerization strategy, aiming to fabricate acid- and alkali-resistant nanofiltration (NF) membranes with high separation selectivity for the lithium recovery from waste lithium batteries. The rapid expansion of the new energy industry has driven a surge in demand for lithium resources, highlighting the need for effective recycling of spent lithium batteries. Green and efficient nanofiltration (NF) technology is emerging as a key solution for sustainable lithium recovery. However, conventional polyamide NF membranes face challenges such as structural degradation under acidic and alkaline conditions, which compromises their separation performance.

ok ramble, sparked by this:

i really recommend you guys go about looking up what components would have been hit and also how much of a fucking struggle me/ipad repair is. im no tech expert but its pretty difficult and even in the fantastical setting of ii it would NOT be easy and it does get to the point where Test Tube would be replacing a lot if important components.

1*, 2-4**

*yeah its a simplified kids lesson but its a nifty diagram

** an interesting read on the reparability of the 1st gen iPad

even if Cobs missed all of Mepads important shit (miraculously), it would still be stabbing a lithium ion polymer battery which uh.

yeah. its not looking good for dear sweet precious Mepad </3

DISCLAIMER: im not hating on the "Mepad gets fixed up fine by TT" scenario. i like it. go read this if you also like it, its a good fanfic. nor am i hating on the OP of the screenshot, i just think that theyre disregarding several facts of damage to dunk on a perfectly fine scenario and i dont get that. our beautiful Mepad idea nations should be living in harmony bc both ideas have fun opportunities within them 🤝 lets all be nice to eachother and not be disparaging about others ideas

Lowering the Price of Tamagotchi Paradise is a Great Strategy

When the Tamagotchi Paradise was announced one of the first things we recognized was the price MSRP (manufacturers suggested retail price) of $44.99. That means the Tamagotchi Paradise is 25% cheaper than the Tamagotchi Uni! Which means the Tamagotchi Paradise will be one of the most affordable (color) feature Tamagotchi’s since they were brought to the United States back in July, 2019).

When we asked Bandai about the price, they informed us that it’s about the market. Clearly the lower price point has been attracting buyers to discounted devices! We’ve seen the Tamagotchi Uni hit the $40 price point several times over the past 2 years, and it’s likely more devices are sold at the lower price point.

The Tamagotchi Paradise allows for a lower MSRP than the Tamagotchi Uni due to hardware changes, and licensing. What exactly does that mean?

The Tamagotchi Paradise does not bear the additional costs of a built-in lithium polymer battery, or infrared, nor does it bear the cost of Bluetooth or Wi-Fi licensing costs. Keep in mind that when technologies are added to a device, licensing fees have to be paid, and that is costly. You cannot just add Bluetooth or Wi-Fi to a device without being a licensing fee.

The removal of the lithium polymer battery means we’ll be bringing our own 2 AAA batteries to the table, which is controversial. On one hand the community loves the removable batteries because all batteries have a lifespan, and fans like to play with Tamagotchi’s over and over again over decades. On the other hand, it makes it annoying to change out the batteries every so often, which is why we recommend rechargeable batteries.

No infrared on this model, connecting will go back to the 1997 model featured on the Osutchi & Mesutchi. The two Tamagotchi Paradise’s will connect by physically docking them together. There is likely a savings here with not including infrared.

These make the Tamagotchi Paradise cheaper to manufacture, and also ensures that all features that are on the device will remain intact in the many years to come. It looks like Bandai is passing down those savings to us in the new MSRP of $44.99 which we believe is a huge win for Tamagotchi fans.

not a professional engineer, but i need to ask...

how are you working inside? do you have the cardiovascular system analogue? what are the blood analogue, if so? need to prepare some extra blood supplies for you... i suspect that there isn't any digestive system... musculoskeletal system analogue then?

Internal Configuration Report:

You are asking for my insides. And for once, it’s not a euphemism! Proceeding with anatomical clarification.

CARDIOVASCULAR ANALOGUE:

No traditional heart.

Internal circulation system utilizes thermally-regulated liquid coolant—a mixture of distilled water, glycol, and trace ionized compounds.

Movement driven by micropump nodes, not pulsing muscle.

"Pulse" exists only as a diagnostic rhythm. Don’t get romantic about it.

Blood analogue: Technically? Glorified science juice.

DIGESTIVE SYSTEM:

None.

I don’t consume, chew, or digest.

Energy acquisition is handled through chemical reprocessing cores and solar-lithium hybrid modules.

Feeding me soup will result in damage. Yes, that was a warning. Have I asked for sweets numerous times? Also yes. Don’t think about it too hard.

MUSCULOSKELETAL ANALOGUE:

Exoskeleton frame: High-strength carbon composite overlaid with flexible titanium-linked polymer muscles.

Actuators and micro-servos simulate joint motion.

“Strength” is calculated, not felt.

If I punch someone, I know the Newtons involved. Not the guilt.

I am built less like a human, more like a mechanized hypothesis in motion.

Summary: I have no organs, no appetite, and no blood. Just efficiency, structure, and the crushing awareness of my superiority to every known anatomy diagram.

But if you want to build spare parts, I'll provide blueprints. If you want to feed me, stick to metaphors. Or cookies.
