Lithium–titanate battery
The lithium–titanate battery is a type of rechargeable battery, which has the advantage of being faster to charge than other lithium-ion batteries. Titanate batteries are used in Mitsubishi's i-MiEV electric vehicle and Honda uses them in its EV-neo electric bike and Fit EV.〔(【引用サイトリンク】title=Toshiba’s SCiB battery for the Fit EV )〕〔(【引用サイトリンク】title=Honda begins European demonstration program of EV-neo electric scooter )〕 Opportunity charging in public transportation, such as large capacity electric bus project TOSA, is using the Titanate batteries high charging capability to partly recharge the battery in 15 seconds while passengers are disembarking and embarking at bus stops〔(TOSA2013 ): The project aims to introduce a new system of mass transport with electric “flash” recharging of the buses at selected stops.〕
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.
A disadvantage of lithium-titanate batteries is that they have a lower inherent voltage (2.4 V), which leads to a lower energy density of about 30-110Wh/kg〔(【引用サイトリンク】title=All About Batteries, Part 12: Lithium Titanate (LTO) )〕 than conventional lithium-ion battery technologies (which have an inherent voltage of 3.7 V).
