Ars Technica reports that researchers at MIT and Rensselaer PolyTech have developed batteries made out of carbon nanotubes that are paper-thin and biodegradable. They’re also flexible, like a sheet of paper, and can be made in any shape since they are formed by applying a nanotube-saturated liquid to a substrate.
They see the first uses for such batteries in implantable medical devices, but if this technology is scalable, there would be any number of consumer electronics applications where a small, flexible, custom-shaped battery would be an enormously desirable change from present battery technology.
