▎ 摘　　要

Well dispersed Co2GeO4 (CGO) nanoplates and CGO/reduced graphene oxide (RGO) nanocomposites are prepared via hydrothermal method and characterized as novel lithium anode materials for the first time. Electrochemical measurements demonstrate that the CGO/RGO nanocomposites exhibit a large reversible capacity of 1250 mAh g (1) for the first cycle and a capacity retention of 1085 mAh g (1) after 100 cycles. Remarkable rate performance was also recorded. The superior electrochemical performance of the CGO/RGO nanocomposites electrode compared to the pure CGO electrode can be attributed to the well dispersed RGO which enhances the electronic conductivity and accommodate the volume change during the conversion reactions.
