摘要
主要针对锂离子电池的寿命进行研究,期望用1～2年的加速寿命实验周期,建立电池衰减模型,完善实验机理及分析成果,用来模拟验证其至少15年的使用寿命.重点研究循环寿命对电池使用寿命的影响.通过定周期的对电池进行参考性能测试,得到容量值C、内阻R及功率能力,来评估其对电池使用寿命的影响,从而进一步评定电池寿命衰减的机制.
The life of lithium-ion batteries is researched. 1 to 2 years of accelerated life test cycle is hoped to set up battery attenuation model, and to gradually perfect the mechanism of experimental and analysis results, to simulate verify the service life of at least 15 years. The effect of cycle life to battery life is focused. Through fixed cycle to process reference performance test （ RPT）, battery capacity value, resistance and power capacity is got to evaluate its influence to the service life of the battery, and to assess attenuation mechanism of battery life.
