Greetings yet again folks! Before today's news i should ask this: what would you think when wearable tech is mentioned? AR/VR glasses? A smart watch? a pair of fancy glasses? nfc based products or was it something else for you?

what if i tell you there is a battery that is so stretchable and bendable that can be tailored between linings of your clothes now what would you think?

Meet the age of stretchable batteries people!

in that case i should mention when people of today was so busy with nonsense politics and rightist or leftist ideas there were quite a race between the biggest tech schools and companies for manufacturing this tech such as apple, samsung, stanford, Yokohama National University, zotach (japan based wearable tech company), sydney's UNCW, Australian research comity and more.. you get the idea..

so what is this tech in its core?

basically building more softer and more long term reliable materials to replace our common daily use batteries

in term of materials it nearly uses our common li-on batteries but these are mainly works like electrodes and often use polymers, hydrogels, and other flexible materials for electrodes and electrolytes. we can see in recent inovations include the use of stretchable conductors like gold nanowires or carbon nanotubes.

BUT what these mambo, jambo, wombo, combo means for public eye?

much longer active use time, higher adaptability, flexible form factor yet lower energy and power density.

for now this tech has been used in certain medical implant cases, wearable techs, tv's, and watches for now but there is some attempts to imply this in to textile industry recently..

and japan is seems like ahead of the race for now with Zotac’s VR GO 4.0 backpack

this is a backpack pc and its power source is tailored between in entire foam/ fiber pad. this "pc" is specifically made for VR/AR and streaming which includes

11th Gen Intel Core Mobile i7-11800H processor, an NVIDIA RTX A4500 graphics card with 20GB of GDDR6 memory and 7,168 CUDA cores, 16GB (32GB maximum) of DDR4 RAM, an M.2 slot for storage, a 2.5′ SATA 3 hard drive/SSD bay for storage, three USB 3.1 Type-A ports, a single USB 3.1 type-C port, DisplayPort, and a 12V DC outlet, all powered by dual 86.4 watt-hour hot-swappable batteries.

like i said this tech is still under developement stage and people still trying to make this tech better than other compettitives...

time will show us what will it gonna be turn out at the end..

lastly.. see you guys tomorrow...

Xanthan gum, derived from plants like cabbage and known for its carbohydrate content, serves as a natural protective barrier in cosmetics. In a recent development, this remarkable substance has been harnessed to create a protective shield for battery electrodes, rather than for the skin. Professor Changshin Jo from the Graduate Institute of Ferrous & Eco Materials Technology and the Department of Chemical Engineering and Jooyoung Jang, a PhD candidate, from the Department of Chemical Engineering at Pohang University of Science and Technology (POSTECH), have crafted a protective film by blending polymers. This film enhances the durability of battery electrodes, and their research findings have been featured in the international journal Energy Storage Materials. With renewable energy sources like solar power being inherently intermittent, the importance of energy storage systems (ESS) is steadily growing. ESS technology enables the capture and efficient use of electricity when needed, making it a crucial element in harnessing renewable energy. While lithium-ion (Li-ion) batteries have traditionally been employed for ESS applications, their high cost and concerns about lithium depletion have prompted ongoing research into alternative solutions.

Converting a battery backup to Lithium because I hate myself

I've got a whole bunch of battery backups in my home, one on each computer, and a big one in my server rack in the basement. I've also got a few out "in the wild" at some of my family's places. They're great, where I live in the northeast US, the power grid is stable enough that most outages are only minutes long, and these backups (technically called a UPS - Uninterrupted Power Supply) do a great job keeping computers running through them.

My issue is the batteries. They all run on lead acid batteries, aka the same kind that's in your car, and they dont last long in this kind of environment, I'm lucky if I get 3 years out of one. On top of that, their battery life detection is terrible, It's about a 50/50 shot whether I get a warning about a dead battery pack before the next power outage takes it down without warning. Keeping track of that with just one or two is annoying, let alone 10 of them!

Lithium UPS's exist, and theoretically last many years longer, but they are many times more expensive than a normal backup. I'd like to not spend new-car money replacing a dozen UPS units, so I did some math instead.

I have a husk of a ups (no battery), and I tested it out: the open circuit voltage on the battery cable is 27.6 volts, which just happens to be almost the exact voltage needed to float charge a series of 8 Lithium-iron-phosphate (LiFePo4) batteries!

Why is that exciting? Usually when you think of lithium batteries, you think of lithium-ion (also can be called lithium-polymer) batteries. These are the batteries in your laptop and phone... And also Tesla cars. They hold more energy than a LiFePo4 battery, but are very sensitive to temperature, over and under-voltage, over-charging, and over-current conditions. Abuse them too hard, and they swell up and pop! That's why Teslas seem to catch fire more often than other cars: most other companies gave up range for a battery chemistry that isn't a ticking time bomb, like LiFePo4.

These LiFePo4 batteries can take a beating compared to Li-ion ones. Most importantly, they can be "float" charged, that is, left on the charger 24/7, without worrying about overcharging it and blowing caustic smoke everywhere. This is critical, because I'm attempting a direct drop-in swap for the old lead battery in this UPS, because float charging a lead battery is basically a requirement, and doing that to a Li-ion battery is asking for a fire!

Using a Li-ion pack would require a custom charging circuit, as the UPS's 27.6V is not correct for any configuration of Li-ion, and would either under charge the pack, losing me 50% of my capacity, or overcharge it, and make it explode. It would also have to stop the batteries from being float charged, again to keep the battery from exploding, while fooling the UPS into thinking a battery is still attached so it doesn't beep at me all the time, and my head is spinning just thinking about how that would work. Much easier to give up capacity for a simpler, and more robust battery.

This UPS can deliver 900 watts of power on battery, that equates to roughly 30 amps of current from the 27.6V battery pack. Adding a safety factor, I bought a BMS (Battery Management System) rated to 50 amps. A BMS is essential, as it offers extra protection against short circuits, over and under-charging and temperature cutoff. Also cell balancing, which keeps all the cells at the same level of charge during use (if they go out of sync-that's bad, is all I'll say for now). The batteries are rated for 120 amps continuous draw, so I am well under the limit where the cells would self-immolate.

With all that said, here's the guts:

Looking close, you might see that I had to cut some plastic out to make it all fit. That's an error on my part-I didn't measure right. If I make more, I'll definately be using a smaller cell, so it will be a proper "drop in" mod. Lots of drilling, cutting, and filing to make this all fit!

It took several hours to link up the cells, terminate the balancing wires (the small red spindly ones), and and stuff them in the battery box. That's a LOT longer than I was hoping it would take, but the on-the fly mods took a lot of time. but eventually, it all fit in, and I was able to test it:

It works! I unplugged it from the wall, and it stayed on! For now, I am in full helicopter parent mode, since I don't want to deal with a lithium fire, even though my math checks out and the UPS should never get the the point that these cells are ever "abused". I only leave it on when I'm in the room, and when I leave, I unplug from the wall, and remove the red lead from the battery, so no charge enters or leaves while I'm not there to watch it.

In theory, the only issue with this retrofit will be a useless runtime meter. The "minutes of runtime" meter is measuring the voltage of the battery as it discharges to estimate how much longer it will last, and the voltage drop over time is different for lithium and lead, so the meter won't be measuring accurately. Once I'm confident it won't explode randomly, I will likely install it permanently somewhere in one of my compters.

Wish me luck!

please share with the class the most novel misadventure in good lab conduct you've had to live through. bureacratic or clerical issues included + bonus points if you're implicated

Once upon a time, there was a trio of research assistants. These research assistants worked with alkali metals in their daily life; they knew quite well, of course, that alkali metals react with water (rapidly and violently) and air (slowly, but the oxide created is explosive.)

These research assistants made some Li-metal batteries to test the durability of a certain polymer material under the electromagnetic and physical stress of being in a battery. They took the batteries that shorted back to the wet lab and opened them up to remove the polymer material and see if it had any notable differences to before it was tested. The disassembly went fine (though they had to use a manual file as using a mechanical one would have possibly created a heat enough to have ignited any lithium oxide that was there.) They removed the polymer material and stored it for safekeeping, but now they had a bunch of lithium metal outside of inert atmosphere.

The oldest research assistant wanted to know where the liquid to store the lithium metal was (as in organic solvents lithium generally won't oxidize.) The middle research assistant had fucking had enough after the filing escapades, and gestured vaguely to the back of the lab. The youngest research assistant figured that they'd go look for some mineral oil, since that's the most commonly used liquid to immerse alkali metals in for safekeeping.

However, when the oldest and youngest research assistants looked around the lab, they saw that the mineral oil was out of reach of both of them. (Neither of them was >165cm, you see, and it was on a high shelf.) However, that was fine. There were other organic solvents in the lab, at a much more reasonable height (in the flammables cabinet.) The oldest research assistant looked through the cabinet, but most of them were not in sealed containers- water might have gotten in. In addition, some of them were less than 99% what they were supposed to be, therefore some of that impurity could be water.

The oldest research assistant pulled out one of the few sealed bottles that was 99.9% pure (HPLC grade). They poured some of the liquid into a beaker- enough to cover all the pieces of lithium metal that remained. The liquid, by the way, was 99.9% pure dry methanol.

The two research assistants carefully placed the lithium metal in the beaker in the fume hood. They then proceeded to immediately slam the fume hood sash down.

You see, dear reader, alkali metals don't just react with water. Though that's what you'll see if you read about them online, they actually just really like to form hydroxides. So if something has an OH group attached to it, alkali metals will react. Oftentimes more rapidly than with water!

The lithium chunks were fizzing, hissing, and skidding around on the surface of the water inside the fume hood. Luckily for us, however- I was the youngest research assistant in this scenario- we were working with lithium, the most electronegative and lightest of the alkali metals. Due to this higher electronegativity, it reacts less rapidly with OH groups than the heavier alkali metals do. So there was no explosion, as fun as that might have been with the sash down. The moral of the story is to use your head about chemical interactions, and don't believe everything you read on university EHS websites.

Anyway, the oldest research assistant is working at one of the top universities in the country now. I wish them all the best.

Flexible solid electrolytes for all-solid-state lithium batteries

Garnet-type solid electrolytes are attracting great interest due to high ionic conductivity and excellent electrochemical stability against Li metal. However, the thick electrolyte layer and rigid nature as well as poor interfacial contact are huge obstacles for its application in all-solid-state lithium batteries. Currently, researchers in China provide a promising strategy toward realizing 20 μm-thick flexible Li6.4La3Zr1.4Ta0.6O12-based solid electrolyte for high-performance all-solid-state lithium batteries.

They published their work on July 4 in Energy Material Advances.

"The development of high-energy-density and safe all-solid-state lithium batteries employing solid electrolytes is imperative," said author Xiayin Yao, professor with the Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences (CAS). "The cell-level energy density of all-solid-state lithium batteries highly depends on the thickness of solid electrolytes and inorganic solid electrolyte thin film generally show thick and rigid nature."    

Yao explained that polymer-in-ceramic garnet-based electrolytes can substantially overcome the above-mentioned challenges of garnet-type ceramic electrolytes.
