Walls and tiles could soon power all your electronics with this innovation.

Researchers at the Rice University in Texas, USA, have created a lithium-ion battery paint that can be applied to any surface. The battery-based paint was experimented on bathroom tiles, which were able to power a set of LED lights for six hours, and provided a steady 2.4 volts.

The lead author of the project, Neelam Singh, commented that her team had spent hours formulating, mixing and testing the paints. The working concept means that traditional packaging for batteries can have a “more flexible approach that allows all kinds of new design and integration possibilities for storage devices.”
