Electric Car Battery Research: Graphene Foam For Faster Recharging?

Graphene is described as a “wonder material” within the scientific community, winning the 2010 Nobel Prize in Physics.

It’s incredibly light, incredibly strong and very simple. Made up from sheets of carbon only a single atom thick, it’s the material’s potential use in batteries that has us excited.

Graphene foam, says arstechnica, is the latest technology to be suggested for battery technology.

To create it, graphene is “grown” on the surface of a metal foam, a three-dimensional mesh of metal filaments. When the metal is processed away, you’re left with graphene foam. The resulting material is both flexible–just like regular graphene–light, and strong.

It also has great electrical conductivity characteristics, as well as a large surface area for charge carriers to exhange electrons–both desirable features for a battery electrode.
