LG Builds Working Flexible Cable Battery
MrSeb writes with news on work toward flexible batteries good enough for Real World use (you have to power those flexible electrionics somehow). From the article: "LG Chem ... has devised a cable-type lithium-ion battery that's just a few millimeters in diameter, and is flexible enough to be tied in knots, worn as a bracelet, or woven into textiles. The underlying chemistry of the cable-type battery is the same as the lithium-ion battery in your smartphone or laptop — there's an anode, a lithium cobalt oxide (LCO) cathode, an electrolyte — but instead of being laminated together in layers, they're twisted into a hollow, flexible, spring-like helix. flexible batteries have been created before — but they've all just standard, flat, laminated batteries made from sub-optimum materials, such as polymers. As such, as they have very low energy density, and they're only bendy in the same way that a thin sheet of plastic is bendy. LG Chem's cable-type batteries have the same voltage and energy density as your smartphone battery — but they're thin and highly flexible to boot. LG Chem has already powered an iPod Shuffle for 10 hours using a knotted 25cm length of cable-type battery."
Original paper (Extreme Tech claims it is paywalled, but it looks like it's not). The hollow core seems to be the key: "Moreover, a nonhollow anode proved to have serious problems with penetration of the electrolyte into the essential cell components such as the separator and active materials ... However, we were able to overcome these drawbacks by devising a unique architecture comprising a skeleton frame surrounding an empty space, that is, a hollow-spiral anode with a multi-helix structure This design enables easy wetting of the battery components with the electrolyte and the hollow space allows the device to compensate for any external mechanical distortion while maintaining its structural integrity. In addition, this helical architecture possibly enables the battery to be more flexible, owing to its similarity to a spring-like structure."
Before Apple 'invents' it!
I'm not a lawyer, but I play one on the Internet. Blog
That will wear out quicker than the display cable on an 80's digital diary...
It's a cool technology, but the iPod shuffle can run for a billion years plugged into a potato. Can we get some actual performance data please?

LG Builds Working Flexible Cable Battery
Got to power those flexible vibrators somehow.
I don't care if it's a couple meters long, I just want a fat-ass cable made of four of these in series (possibly several parallel) with an alligator clamp on each end for jump-starting cars.
(Yeah, I know you can trivially rig up a box with IMR26700 or IFR26650 cells, or even good Li-polymer cells, to do this. But I don't want it to look like a box, I want it to look like a paraplegic jumper cable.)
worn as a bracelet, or woven into textiles
Just what we need, clothing that overheats and combusts.
Perhaps finally something that makes women interested in science.
Don't fight for your country, if your country does not fight for you.
you have to power this [sic] flexible electrionics [sic] somehow
Good grief. Also, linking to the article inside a quote from the article? Very meta.
systemd is Roko's Basilisk.
Flexible lithium power source combined with flexible OLED display means you could have a woven, wearable, textile display. Could be handy as a safety garment for construction workers, and probably fodder for an ugly sweater contest.
Judging by my headphone wire failure rate, I'd say this idea sucks balls.
Will change things. Big time.

Finally FSM batteries. We are saved. But what will the voltage be?
I forgot to plug in my jacket last night.
...given that lithium batteries are notoriously unstable? I'd sure as hell not wear that.
CLI paste? paste.pr0.tips!
Given that the US nanny-state has outlawed pajammas that can catch fire when placed in the flame of an acetaline torch for 20 minutes, I wonder how they will respond when faced with clothing that can outgass, catch fire, and explode under the right circumstances?
"Worn as a bracelet." Oooooooh. Live Strong would really mean it if I could attach electrode brass knuckles and taze someone with my epic battery bracelet.
I mean, my battery coat has a warming function, but I mostly don't need that because the coat gets plenty warm when I use batteries heavily. And if I do get cold sitting on a bench, or that cute girl next to me does, the warming function is a nice touch. I imagine if you're living in a cooler climate it can be a lifesaver. Mostly I use the jacket for my infinite and frantic mobile gaming habit. Got the glasses too, but mostly I prefer to use my imagination and the little screen for details - I imagine that will change when the graphic world overlays get better...
Oh, the clothes... The jacket's loaded with kinetic energy generators. But when I feel sporty I put on my heavy kinetic pants. That way I *will* exercise on the way to work. And produce a ton of useful energy as a practical side result. Battery low? Start working, boy!
I kinda have the "wimp" version of the kinetic pants, though. Some of my friends have theirs locked to a 5+ setting - but those are the friends I almost never see wearing kinetics... And looking too damn proud of themselves when they do.
But what I'm really looking forward to looks ready to hit prime-time in about 3-4 more years - fully user-safe versions of the synthetic lung... Unlike the shit the Special Forces are using today, this will actually be safe. It pumps oxygen into your blood at a ridiculous rate, and will eventually come with an optional add on - Hæ+ full blood transfusion. Haemoglobin Plus enhanced blood cells grown with your own stem cells and having the new and better oxygen carrier protein, that also as a benefit *doesn't* turn toxic if the protein leaves the cell like normal Haemoglobin does... I can already imagine the eventual ads... "It just might save your brain".
There's already all these blood variants that are really useful for hypothermic heart surgery and the like, and they're saving tons of lives.
I really do need a new lung to hold off the heart&lung transplantation, though, and it looks like I'll get it before most potential users.
That's the tech which sold me on getting used to wearing battery clothing: I do not want my synthetic lung to run out of power. Ever.
I'm a dreamer, the world is my playpen. But hey, I'm a serious person, I can't dream all the time.
What even are you talking about, and where can I read the rest of this book?
