Wired: ‘Super batteries’ to be 3D-printed from graphene ink
“We’re trying to achieve a conductive ink that blends the fantastic properties of graphene with the ease of use of 3D printing to be manipulated into a structure that’s beneficial for batteries and supercapacitors,” explains Craig Banks, a professor of electrochemical and nanotechnology and leader of the three and a half-year project.
