Exploiting efficient and rechargeable lithium-ion batteries (LIBs) is of great significance, which stimulates us to procure suitable electrode materials. Herein, a novel anode material is fabricated via encasing CoxZn1-xS/Co9S8 nanoparticles into N-doped reduced graphene oxide (rGO) skeleton. Owing to the open and accessible structure constructed by the conductive rGO as well as the optimized Co:Zn ratio, the as-prepared electrodes achieve good lithium storage capacity (742.2 mAh g(-1) at 1 A g(-1) and 222.4 mAh g(-1) at 10 A g(-1)) and an excellent retention rate of 105.9% on 1000th cycle at 1 A g(-1), making them promising anode candidate for highly reversible lithium storage in long-term cycles.
