New Li-Ion Technology Charges 10x Faster, Holds 10x More

graphene

Inside Li-ion there are innumerable layers of graphene, a one-atom-thick sheet of carbon atoms. Lithium ions fill the spaces between these layers and when the bettery is being charged the atoms make their way to the edge of the sheet in order to get down to the next layer and make room for more ions. The speed of recharging is limited by how quickly these ions can get from layer to layer.
