英文摘要：

In order to meet the needs of high power electric devices such as electric vehicle, battery materials with high energy density and high power are becoming necessary. Lithium titanate is a kind of ideal material for lithium anode, for its higher safety and excellent cycle performance compared with other anode materials. But the poor electronic conductivity limits its application. The current research on Li4Ti5O12 was summarized, and its development direction was proposed.
