Lithium-titanate battery

Lithium-titanate battery

The Lithium-titanate battery is a type of rechargeable battery, which has the advantage of being faster to charge than older Lithium-ion batteries. Some analysts speculate that Lithium-titanate batteries will power electric cars of the future.cite news |first=Lewis |last=Page |title=Japan kicks off electric car format war |url=http://www.theregister.co.uk/2008/07/21/electric_car_format_wars/ |publisher="The Register" |date=2008-07-21 |accessdate=2008-07-21 ]

A lithium-titanate battery is a modified lithium-ion battery that uses lithium-titanate nanocrystals on the surface of its anode instead of carbon. This gives the anode a surface area of about 100 square meters per gram, compared with 3 square meters per gram for carbon, allowing electrons to enter and leave the anode quickly. This makes fast recharging possible and provides high currents when needed. [ [http://www.newscientist.com/article.ns?id=dn7081 Graham-Rowe, Duncan. "Charge a battery in just six minutes".
