Graphene applications are sparking a materials revolution. Batteries made of graphene materials not only have a significantly higher capacity than lithium-ion batteries, but also greatly reduce their weight and volume, and greatly shorten the charging time. If used in TSLA electric vehicles, the cruising range is expected to be extended from more than 400 kilometers to more than 1,100 kilometers... This dream is becoming a reality. The weight is reduced by 80%, the volume is reduced by 67%, the charging only tak
