摘要：

Ball milling in combination with heat treatment was used to prepare S/C composite cathode materials (sulfur containing was 42 wt%). In this paper, the effects of different binders PTFE, gelatin and PEO for lithium-sulfur battery were studied respectively. Cyclic voltammetry (CV) and constant current charge-discharge characterized the electrochemical properties. The results showed that gelatin and PTFE as a binder presented positive evaluations for the electrochemical performance of sulfur positive electrode. In the experiment, the discharge capacity retains 741.2 mAh/g(based on sulfur weight) after 50 for PTFE at 0.2 C. Gelatin as a binder, the discharge capacity was 788 mAh/g after the 50 cycle for the cycles at the current of 0.2 C.
