英文摘要：

Submicron - sized LiNi1/3Co1/3Mn1/3O2 cathode materials were synthesized using a simple self- propagating solid- state metathesis method with the help of ball milling and the following calcination. The effects of calcination atmosphere and time on the structure and electrochemical characteristics of prepared LiNi1/3Co1/3Mn1/3O2 samples were systemically studied. The research results showed that calcination at 900℃ in air atmosphere for 20h could obtain the LiNi1/3Co1/3Mn1/3O2 material with optimal electrochemical characteristics.
