▎ 摘  要

Mesoporous lithium titanate/reduced graphene oxide anode material was synthesized by a simple hydrothermal method. The morphology and structure of the obtained materials were characterized. The electrochemical properties of the obtained materials were tested. The results show that the lithium titanate/reduced graphene oxide anode material posseses high specific surface area and the lithium titanate nanosheets are not easy to agglomerate; the initial discharge specific capacity is increased to 182. 2 mA . h/g at 0. 1C rate; and the cycling performance is greatly improved, with a cupacity of 160. 6 mA . h/g after 500 cycles at 5C rate.
