Crumpled Graphene Builds Better Batteries

Jan-25-18 Crumpled balls of graphene could lead to better batteries by eliminating the need to distribute lithium into another material.

The batteries were developed by a team from Northwestern University, and build on previous research by Jiaxing Huang using crumpled graphene. In typical batteries, lithium is distributed into another material in the anode, which weakens the battery’s performance but also prevents dangerous dendrite growth. As an alternative, the new battery design features crumpled graphene balls that are stacked to form a porous scaffold, which prevents dendrite growth while also withstanding the volume fluctuations of the battery’s cycles.
