摘　　要：研究了以Li1.04Mn1.96O4为正极,中间相碳微球(MCMB)为负极的AA型锂离子电池。在室温条件下,电池的1C放电容量达500mAh,比能量达到95Wh/kg和210Wh/L,循环400次时,其容量仍为初始容量的85%,并具有较好的倍率特性。55℃荷电贮存7天后仍具有较好的充放电性能。电池在170℃荷电放置的条件下,不起火爆炸。AA size Liion batteries using Li1.04Mn1.96O4 as cathode electrode and MCMB as anode electrode were investigated.At room temperature,the battery's charge capacity was 500?mAh at 1?C and the specific energy was 95?Wh/kg and 210?Wh/L.After 400 cycles,its discharge capacity was 85% of the initial capacity.Stored seven days at 55?℃,it still had excellent charge/discharge performance.Stored at 170?℃,the battery would no catch fire or explode.
