Using electrodes in a fluid form, researchers at Linköping University have developed a battery that can take any shape. This soft and conformable battery can be integrated into future technology in a completely new way. Their study has been published in the journal Science Advances.

It's a weird world we are living in, I don't understand how this works, but it's cool. 👍

[–] subignition@piefed.social 28 points 1 week ago

Oh this is awesome. I can see so many cool applications for this in wearable electronics and custom form factor batteries. I hope their research into improving the voltage pays off.

Finally, I can add a layer to my tribal tattoos that can charge my phone.

You have fun charging your phone, I'm charging the capacitors I embedded into my knuckles.

Was that One Punch Man's secret all along?

I can't wait to charge my laptop with my Affliction t-shirt

Actual new battery tech? I didn't see the capacity listed/compared to a normal lith-ion of the same volume but it does say they have some issues with voltage. I'm not sure how annoying that actually is (not super good with electricity) but this looks rather promising. Might see smart watches and similar devices without any flat hard surfaces using these combined with flexable screen tech. Course like always this stuff is extremely reliant on the capacity being workable, if it's too much less than the equivalent in lith-ion it's just not going to get used.

An inconsistent voltage is a bit of a deal breaker if it's a significant swing. For example, AA batteries are supposed to be 1.5v. Typically you can measure them at 1.7v when they're brand new, and that's fine. The voltage will drop as it's used and devices tend to stop functioning when the battery reaches about 1.3v.

That's a fairly narrow range of voltage required to keep the device working correctly.

They say the voltage is less than a AA battery at 0.9v, but how much volume is needed to hit that? Can't you exceed that by, you know, just adding more volume?

Battery voltage increases in series.

[–] gothic_lemons@lemmy.world 16 points 1 week ago (1 children)

Ok so like we gotta wait for season 2 for it to officially become a series and get stronger? Then each new season more volts? Huh science isn't that hard actually

Which increases ESR and effectively reduces current, requiring larger cells/more cells in parallel.

A battery’s voltage doesn’t change with size. AAA batteries up to D batteries are all the same voltage.

Now we gotta be careful to not let either the magic smoke nor the energy juice leak from our machines

More than ten devices per person will be connected to the Internet simultaneously? Why do I think this is a future we should be fighting against? Cool battery still.
