Study of metal-supported carbon matrix as a high-capacity anode for Li-ion battery

Study of metal-supported carbon matrix as a high-capacity anode for Li-ion battery Tin–graphite composite with 20 wt. % metal content as well as its structural and electrochemical characteristics are presented. Synthetic graphite—super flake type—was used as object for the modification experiment. Chemical reduction was applied for the loading process, which was carried out under inert argon atmosphere. Composite with specific morphology and improved electrochemical behavior was prepared. The obtained material shows higher discharge capacity as well as increased initial charge–discharge coulomb efficiency, compared with the unmodified one. The supporting metal morphology, the type of graphite, and the preparation process taken together generally affect the improvement of the electrochemical performance. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Ionics Springer Journals

Abstract

Tin–graphite composite with 20 wt. % metal content as well as its structural and electrochemical characteristics are presented. Synthetic graphite—super flake type—was used as object for the modification experiment. Chemical reduction was applied for the loading process, which was carried out under inert argon atmosphere. Composite with specific morphology and improved electrochemical behavior was prepared. The obtained material shows higher discharge capacity as well as increased initial charge–discharge coulomb efficiency, compared with the unmodified one. The supporting metal morphology, the type of graphite, and the preparation process taken together generally affect the improvement of the electrochemical performance.
