There are a range of technologies available for energy storage, each having a number of tradeoffs in terms of capacity, weight and performance. Capacitors are quick to charge and lightweight, but do not have a large capacity. Batteries are capable of retaining more charge, but are heavy and take a long time to recharge. Graphene is currently known as the best conductive material. The electron mobility of graphene exceeds 15000 cm2/(V·s) at room temperature. Its resistivity is only about 10-6 Ω·cm, which is the smallest resistivity material in the world. Because of these excellent properties, graphene has the potential to produce high-performance batteries, supercapacitors and other fields.
