Lithium titanate as anode material for lithium-ion cells: a review

Lithium titanate (Li4Ti5O12) has emerged as a promising anode material for lithium-ion (Li-ion) batteries. The use of lithium titanate can improve the rate capability, cyclability, and safety features of Li-ion cells. This literature review deals with the features of Li4Ti5O12, different methods for the synthesis of Li4Ti5O12, theoretical studies on Li4Ti5O12, recent advances in this area, and application in Li-ion batteries. A few commercial Li-ion cells which use lithium titanate anode are also highlighted.
