Watch: Paintable battery offers new opportunities

Researchers at Rice University have developed a paint-on lithium-ion battery that can be applied on almost any surface, using only a spray gun.

The rechargeable battery consists of spray-painted representing components in a traditional battery – two current collectors, a cathode, an anode and a polymer separator in the middle. The paint can be applied to most surfaces - researchers tested the battery on ceramic bathroom tiles, flexible polymers, glass, stainless steel and even a beer stein. Lead author Neelam Singh, a Rice graduate student, says the battery is easily charged with a solar cell and could be used with paintable solar cells in the future. Watch the video below:
