Spray-On Lithium-Ion Batteries Can Turn Any Surface Into a Battery

Spray-On Lithium-Ion Batteries Can Turn Any Surface Into a Battery

Researchers at Rice University have developed a truly game-changing battery technology -- paintable or spray-on lithium-ion batteries . This new technology allows any surface to become a battery, which could lead to major advancements not just in energy storage, but in solar power generation, too. The Rice team formulated, mixed and tested various paints to make up the five layered components of a lithium-ion battery: two current collectors, a cathode, an anode and a polymer separator in the middle. Once the right formulations were found, the team sprayed them onto different surfaces including ceramic tiles, glass, stainless steel, flexible polymers and even a beer stein to test how they would bond to the surfaces. Then the real fun began when they put the painted-on battery to work. © Neelam Singh/Rice University According to Rice University , "In the first experiment, ni...
