▎ 摘　　要

Li4Ti5O12/graphene nanosheets (LTO/GNSs) composites are prepared in situ via a sol-hydrothermal process. The LTO are found on the edges and surface of the GNSs, and GNSs give a conductive connection of LTO spheres to constitute a conductive network to improve the specific capacity and high-rate performance of LTO. With the increase of the amount of graphene nanosheets from 0 to 10 wt%, the electrical conductivity of composites increase from 1.78 x 10(-9) S cm(-1) to 2.04 S cm(-1). However, the specific capacity of LTO/GNSs-10 wt% electrode at lower rate (
