Supercapacitors provide the burst of immediate energy that makes it possible for the electrical grid to make instant adaptations. They currently lack staying power and need to be deployed with energy storage . What would happen if someone invented a hybrid device that combined the energy of a supercapacitor with energy storage? Now imagine this new device being made of graphene, rather than lithium, and that it can be used with personal electronic devices like self charging cellphones, or in electric vehicles or in a solar cell. You’ve just read a description of SunVault’s new graphene hybrid storage device.
