What are graphene supercapacitors?
What are graphene supercapacitors? Graphene is a thin layer of pure carbon, tightly packed and bonded together in a hexagonal honeycomb lattice. A Graphene supercapacitor is said to store almost as much energy as alithium-ion battery, charge and discharge in seconds and maintain all this over tens of thousands of charging cycles. How do ultracapacitors […]
