The lithium-titanate battery is a rechargeable battery that is much faster to charge than other lithium-ion batteries. It differs from other lithium-ion batteries because it uses lithium-titanate nanocrystals on the anode surface rather than carbon. This is advantageous because it increases the surface area of the anode from 3 square meters to about 100 square meters, which allows the electrons to enter and exit the anode quickly. This increase in surface area is what allows the lithium-titanate batteries to be recharged quickly and provide high currents when necessary. A disadvantage to the lithium-titanate battery is a much lower capacity and lower voltage than the lithium-ion battery. The lithium-titanate battery is currently being used in battery electric vehicles and computer batteries.
