▎ 摘  要

Nowadays, Lithium-ion batteries (LIBs) are prevalently applied in numerous areas, leading to increasing demand of innovative electrodes with high specific capacities. An advanced CuGeO3/reduced graphene oxide (rGO) structure is designed and fabricated as the anode material taking the advantage of considerable capacity offered by CuGeO3 and stable framework constructed by rGO. The as-prepared CuGeO3 with 30 wt% GO addition exhibits the best electrochemical performance. Specifically, a reversible charge capacity of 909 mAh.g(-1) with high coulombic efficiency of 91.49% at the current density of 100 mAh.g(-1) after 200 cycles is demonstrated, and the rate capacity retains 747.6 mAh.g(-1) with 91.59% capacity retention. These results indicate that the CuGeO3/rGO composite holds great potential in next-generation LIBs.
