Researchers at the Samsung Advanced Institute of Technology have developed a ball made from graphene (a single layer of carbon atoms) that could advance battery technology in a couple of ways. Batteries made from the new material could charge five times faster than current lithium-ion cells. Perhaps more importantly, graphene ball batteries could offer 45% more capacity.
In theory, a battery based on the “graphene ball” material requires only 12 minutes to fully charge. Additionally, the battery can maintain a highly stable 60-degree Celsius temperature, with stable battery temperatures particularly key for electric vehicles. In its research, SAIT sought for an approach to apply graphene, a material with high strength and conductivity to batteries, and discovered a mechanism to mass synthesize graphene into a 3D form like popcorn using affordable silica (SiO2).
