Researchers at Rice University in Texas have created a paintable battery that can be used anywhere. Also impressive -- the battery is rechargeable and can hold a 2.4 volt charge for six hours.
To create this sprayable battery, the team disassembled the chemicals of a lithium-ion battery and converted them into five paints. These paints were then sprayed in a particular order, like a conventional battery cell, onto ceramic tiles. Then the nine tiles were lined up parallel and placed with one tile topped with a solar cell that converted power from a white laboratory light. This produced a steady 2.4 volts for six hours.
The battery was sprayed on…
