锂电池小电流放电的可靠性分析

Analysis on low-rate discharge reliability for lithium batteries

根据水雷电源的特点,对锂电池小电流放电特性及其贮存寿命进行了试验.并利用数理统计的图估法对试验数据进行处理,得出了锂电池小电流放电特性的失效规律.同时应用极大似然法估计出锂电池的可靠度.对在水雷电源中合理地使用锂电池提供了依据.

The low-rate discharge characteristics and the storage performance of Li/SO2 and Li/SOCl2 batteries have been tested according to the mission requirement in submarine mine application. By using graphical-statistical analysis on the testing data, the failure regularity of low drain discharge of the lithium batteries is obtained and the reliability of the batteries is estimated with maximum likelihood. These works provide important basis for reasonable usage of the lithium batteries in submarine mine application.
