Using crumpled graphene balls to make better batteries


January 18, 2018

Lithium metal-based batteries have the potential to turn the battery industry upside down, with possible uses in everything from personal devices to cars. But as lithium gets charged and discharged in a battery, it starts to grow dendrites and filaments, causing a number of problems. The solution lies in a scaffold made from crumpled graphene balls that can stack with ease to form a porous scaffold, due to their paper ball-like shape. Full Story
