These paper batteries made from plants want to replace AA and AAA cells (www.techspot.com)

This is nuts. Conspicuously absent is price, though. Gonna start at five bucks a cell or something?

What I found the problem won't be the price, but the energy density. These batteries last ~~10 times less than~~ tenth of a current one.

[–] metallic_substance@lemmy.world 5 points 2 days ago (1 children)

Ten times less? Do you mean a tenth?

[–] infeeeee@lemmy.zip 2 points 2 days ago

Yes, I found that in a research paper about Zn-Mn batteries

[–] SpaceNoodle@lemmy.world 1 points 2 days ago (1 children)

They claimed the density was comparable, though.

[–] infeeeee@lemmy.zip 1 points 2 days ago

Where do they claim that? I only see they claim that the lifespan is comparable, and the price per kWh will be lower. It's a rechargeable battery so lifespan means recharge cycles.
