Negative voltage of lithium titanate battery

A battery is a modified lithium-ion battery that uses lithium-titanate nanocrystals, instead of , on the surface of its . 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. Also, the redox potential of Li+ intercalation into titanium oxides is more positive than that of Li+ intercalation into graphite. This leads to fast charging (hi.
