Spray-On Lithium Ion Battery

Rice University grad students have designed a battery that can be sprayed onto a surface.

The paint contains layers, each representing a necessary component of a conventional battery -- current collectors made in part from purified single-wall carbon nanotubes, a cathode, an anode, and a polymer separator -- as described in a report published today in Nature authored by Rice graduate student Neelam Singh and her team. Spraying the painted battery is a multilayer process, but when you're done, you have a covered surface that stores energy and discharges it when needed -- that is, a battery.

This technology would be perfect for Philip K. Dick's battery-powered comic books from his 1965 novel The Zap Gun, which refers to a battery within the back cover of a magazine.

I can't resist pointing out that this would be a perfect way to store the power from Larry Niven's sprayable solar power cells - black power - from his 1995 story The Woman in Del Rey Crater.
