Lithium titanate materials become the focus of research and development for cathode material of lithium-ionic battery because of its characteristics such as long cycle life,cheap and good safety.MLi2Ti6O14(M=2Na,Sr,Ba) cathode material have lower potential platform than Li4Ti5O12.Hence,as the cathode material of full battery,MLi2Ti6O14 has higher working voltage and energy density than those of Li4Ti5O12.Thereby MLi2Ti6O14 hopefully becomes popular cathode material of power lithium-ionic battery,and it has better application prospect than that of Li4Ti5O12.The structure of MLi2Ti6O14 was introduced,and the recent progress of synthesis and doping modification were reviewed.Emphasis was placed on the summary and discussion of preparation and doping method for MLi2Ti6O14,and the development prospect was also viewed.
