Advances in 3D printed batteries over the past few months point to the real possibility of a future of cheaper, more energy dense batteries that can be customized for application and shape.

 .

The idea of 3D printing batteries is not entirely new, in fact the first one was made by a team led by Jennifer A. Lewis at Harvard University in 2013. They created a customized printer and special anode and cathode inks to produce a lithium-ion battery, but it wasn’t able to power much. It was only about the size of a grain of sand.

Skip forward 7 years and two companies – Blackstone Resources of Switzerland and KeraCel in the US, have both made significant leaps toward the technology and procedures needed to create full 3D printed batteries. KeraCel received a key patent for ‘for its innovative monolithic solid state battery incorporating a sealed anode structure’ and […]
