Japanese Scientists Work on a Flexible Battery

Japanese people continue to impress me. I don't know if they invented this 'flexible battery thing', but, I'll repeat myself, their researches impress me.


A new type of battery invented in Japan, in the University of Waseda.
This is a flexible rechargeable battery, based on polymers. The
development of this type of battery was conditioned by the permanently
developing industry of portable devices, which become smaller and
smaller each year.
