Spray-On Battery Could Slip Power Into Tighter Spaces

Researchers at Rice University have developed a paint that works as a battery, and it could change the way batteries are produced and reduce energy storage restrictions. The paint-on battery is similar in material balance to traditional lithium-ion batteries. It has five layers -- a positive and a negative current collector, a cathode, an anode and an ion-conducting separator in the middle. But unlike typical lithium batteries, a perfected paint-on version wouldn't carry the same restrictions in design that traditional batteries do.
