The batteries have the ability to be integrated into the surface of the objects, making it seem like seem like there is no battery at all.

A new development out of the Ulsan National Institute of Science and Technology (UNIST) has yielded a new technique that could make it possible to print batteries on any surface.

With recent interests in flexible electronics—such as bendable screen displays—researchers globally have been investing research efforts into developing printable functional materials for both electronic and energy applications. With this, many researchers predict the future of the li-ion battery as one with far less size and shape restrictions, having the ability to be printed in its entirety anywhere.

The research team from UNIST, led by ECS member Sang-Young Lee, is setting that prediction on the track to reality. Their new paper published in the journal Nano Letters details the printable li-ion battery that can exist on almost any surface.
