摘　　要：本文以天然石墨做锂离子蓄电池阳极材料,通过CO_2气体修饰,改善SEI膜状态,使电极放电容量达200mAh/g左右,循环充放电次数超过90次(继续中)。Natural graphite as the material of Li+ anode was used. This graphite was modified to improve the status of SEI layer by CO2 atmosphere. The anode with capacity of discharge up to 200 mAh/g and charge-discharge cycle life over 90 times were obtained and continuing.
