摘要
锂离子电池的应用领域很广阔,在锂离子电池的性能中的无记忆效应、高能量密度等都与其电容有着很大的关联,但是锂离子电池会因多次循环使用而出现老化现象,因此本文主要系统分析研究了锂离子电池循环老化而导致容量下降的机理以及影响,并研究了现行规范中对锂离子电池循环生命周期的测定方法。根据已有测试周期过长的情况,着重探讨了应用曲线拟合的循环寿命测试方法。结果经过试验证实,表明此测试方法大大缩短了测试周期。
Abstract
The application field of lithium ion battery is very broad, in the performance of lithium ion battery no memory effect, high energy density has a great correlation with its capacitance, but the lithium ion battery will be due to multiple recycling aging phenomenon, so the main system analysis of the lithium ion battery cycle aging and capacity decline mechanism and influence, and studied the current specification of lithium ion battery cycle life cycle determination method. According to the existing test period is too long, the cycle life test method of applying curve fitting is emphasized. The test method greatly shortened the test period.
