The new electrode materials are critically important for the development of lithium-ion batteries (LIBs). Herein, we report the synthesis of Germanium sulfide -graphene composite (GeS-G) by facile sonication which exhibits the excellent cycling performance for lithium-ion batteries. Under the condition of charge-discharge rate of 50 mA·g −1 and voltage window of 0.005–3 V, the specific capacity of GeS-G is 170 mAh·g −1 after 100 cycles, which is significantly higher than that of pure GeS. The results of the present work imply that the nanostructure of GeS-G is the potential electrode materials for application in high-performance lithium-ion batteries and enrich the gene bank of lithium-ion battery materials.
