摘　　要：通过优化正负电极材料（ＡＧ、ＬｉＣｏＯ２）的制备工艺，改进电解质溶液的组分和配比，制成了ＡＡ型锂离子蓄电池。在－３７℃～６０℃温度范围里，电池具有良好的放电性能，在室温条件下电池平均初始放电容量大于６００ｍＡｈ，在－３７℃时电池能放出４５％的初始容量，６０℃时可以放出１００％初始容量。电池在１００％ＤＯＤ条件下以０．５Ｃ速率放电，循环充放寿命超过６００次，电池交流阻抗的测量显示了电解质溶液对电池性能的影响。AAsize lithiumion rechargeable battery has been fabricated by optimizing preparation method of positive and negative electrode materials and improving composition and formula of electrolyte solution.The battery has a good performance in the temperature range from -37℃ to 60℃.Its average discharge capacity at first cycle is more than 600mAh.At -37℃ its discharge capacity is 45% of initial capacity,at 60℃,100% of initial capacity.Battery life is more than 600 cycle at 100% DOD,0.5C rate.The measurement of A.C.impedance indicates the influence of electrolyte solution on battery performance.
