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.
