Researchers at Rice University have developed a lithium-ion battery that can be painted on virtually any surface.
The rechargeable battery created in the lab of Rice materials scientist Pulickel Ajayan consists of spray-painted layers, each representing the components in a traditional battery. The research appears June 28 in Nature's online, open-access journal Scientific Reports.
"This means traditional packaging for batteries has given way to a much more flexible approach that allows all kinds of new design and integration possibilities for storage devices," said Ajayan, Rice's Benjamin M. and Mary Greenwood Anderson Professor in Mechanical Engineering and Materials Science and of chemistry. "There has been lot of interest in recent times in creating power sources with an improved form factor, and this is a big step forward in that direction."
