A team of researchers at Rice University have created a lithium-ion battery that can be spray-painted on to any surface. The first surface they tested the 5-layer power-storing combo on was a set of bathroom tiles. Since then, flexible, glass, and steel surfaces — as well as a beer stein emblazoned with the Rice insignia — have been tested and used successfully to store small amounts of electricity. Graduate student and lead author of the team’s report Neelam Singh imagines buildings sheathed with battery-sprayed ceramic tiles that are then covered by solar cells, integrating energy gathering and storage functions on a structure’s exterior skin.
