Researchers from Rice University have cooked up a rather interesting and promising battery technology capable of turning any surface into a lithium-ion battery. The technology consists of five spray-painted layers that make up all the components of a traditional battery, including two current collectors, a cathode, an anode, and a polymer separator in the middle. All that remains is a power source, and as the researchers demonstrated, spray-paintable batteries can be combined with solar cells.
A team of engineers from Rice University in Houston, Texas, constructed what amounts to a full blown battery where all the essential components are integrated into a single nanowire, Physorg.com reports. The research team says their accomplishment could help give researchers a better understanding of electrochemistry at the nanoscale level, and with a bit of tweaking, it could one day be used to power nanoelectronic devices.
