摘要
本文制备了四组不同正极配比的18650电池,并通过分析电池的电性能:不同温度循环、倍率、高低温和安全性能数据。从放电倍率数据能看出,B组和D组电池的放电倍率特性优异;高低温数据中A、B、C三组均表现出高度一致的高低温性能;在常温1C/3C循环条件下,A、B、D三组表现不错,循环次数可以延续到1000次;安全性能结果四组电池均通过测试要求。
Four different 18650 battery of cathode was made.The performance of electrical properties,different temperature cycles,rate,H/L was investigated.From the results,the performance of groups B、C in rate is the best.Group A、B、C in H/L is better than group D.In normal temperature 1C/3C cycles performance,group A、B、D shows good performance and has 1000 cycles.Four different groups all passed in safety performance.
