Researchers develop paint-on batteries

The lithium-ion batteries can be applied to any surface as a series of spray-painted layers.
Graduate student Neelam Singh and her team at Rice University spent a great deal of time mixing and testing each individual layer that makes up one of the batteries; two current collectors, a cathode, an anode and a polymer separator. The team experimented with the batteries by spraying the layers on to several surfaces including ceramic tiles and hooked them up to a solar panel. The stored energy from the circuit was able to power a set of LEDs for six hours.

"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 materials scientist Pulickel Ajayan.
Researchers at Rice University have developed a lithium-ion battery that can be painted on virtually any surface.

So internal pacemakers? My brother says biggest problem with artifical hearts is powering them and teh surgery required to change batteries. This way, all you have to do is spray the battery in and when the battery needs to be changed spray the solvent in and then spray in a new battery.
