Effect of Carbon Coating on Electrochemical Performance of Treated Natural Graphite as Lithium‐Ion Battery Anode Material

Masaki Yoshio; Hongyu Wang; Kenji Fukuda; Yoichiro Hara; Yoshio Adachi

Carbon-coated natural graphite has been prepared by thermal vapor decomposition treatment of natural graphite at 1,000 C. Natural graphite coated with carbon showed much better electrochemical performance as an anode material in both propylene carbonate-based and ethylene carbonate-based electrolytes than bare natural graphite. The effect of carbon coating on the electrochemical performance was investigated by solid-state {sup 7}Li-NMR in conjunction with standard electrochemical techniques.
