Bendable Battery Unveiled

It’s a battery that looks like a piece of paper and can be bent or twisted, trimmed with scissors or moulded into any shape needed. While the battery is now only a prototype, the researchers at Rensselaer Polytechnic Institute who developed it have high hopes for it in electronics and other fields that need smaller, lighter power sources. Unlike other batteries, Prof Linhardt explained, it is an integrated device, not a combination of pieces. The battery uses paper infused with an electrolyte and carbon nanotubes that are embedded in the paper. The carbon nanotubes form the electrodes, the paper is the separator and the electrolyte allows the current to flow
