大功率锂离子电池的制备及电化学性能

Preparation and electrochemical performance of high power lithium ion battery

采用精密的刮刀涂布法制成锂离子电池,并用防爆盖帽作为电池盖帽。利用电化学性能测试对电池进行测试。倍率测试表明电池的倍率可以达到5 C,循环测试其寿命达到400次以上,针刺表明其安全性能良好。电池的容量达到1 300 m Ah以上。

Lithium ion battery was made by precise bladed coating with explosion-proof cap. The safety and charge/discharge performance of LiMn2O4 were analyzed by electrochemical performance measurement. Rate test shows that the cell can reach 5 C, and cycle life of battery can reach morn than 400 times. Cutting through battery with needle shows good safety performance. The capacity of battery is above 1 300 mAh.
