▎ 摘  要

In this paper, CuCo2Se4/reduced graphene oxide (rGO) composites were prepared by a solvothermal method for the first time. CuCo2Se4/rGO is applied as anode material for lithium-ion batteries (LIBs) with excellent per-formance. CuCo2Se4/rGO provides a reversible capacity of 845.49 mAh g-1 (0.1 A g-1) after 200 cycles, which is significantly better than CuCo2Se4 (36.90 mAh g-1). The rate performance of CuCo2Se4/rGO (318.4 mAh g-1 at 2 A g-1) is much better than the pure CuCo2Se4 (15.1 mAh g-1 at 2 A g-1). The results show that CuCo2Se4 /rGO has a promising future in LIBs.
