34698917 story Researchers Spray-Paint Batteries Onto Almost Any Surface 92 Posted by Soulskill on Friday June 29, 2012 @01:39PM from the graffiti-just-got-way-more-fun dept. Warmlight writes "Rice University researchers have created a type of lithium-ion battery that can be spray-painted onto most surfaces. 'Their batteries, outlined in Scientific Reports (abstract), are made up of five separate layers, each with its own recipe — together measuring just 0.5mm thick. To demonstrate the technique, the team painted batteries onto steel, glass, ceramic tile and even a beer stein.' What do you think this will do for future form-factors? Maybe a form-fitting PipBoy-style device that doesn't weigh 30lbs?"
