Power to the Paper: Researchers Turn Paper into Flexible Lithium-Ion Battery

Batteries are the bane of all portable electronics. Bigger, heavier batteries make devices less portable, while smaller batteries lead to low performance or short battery life – or both. But while Stanford’s new lithium-ion batteries don’t necessarily cut down on footprint, they certainly cut down on mass; the new ultra-thin, rechargeable battery has been fabricated on a single sheet of paper, making it super-light, flexible, and as portable as a piece of A4.

The story is too old to be commented.
