Have been determined the self-discharge rate of LR44 type like Zn-MnO Battery and JQF6m type Zn-Air Battery, the results corresponding are 3.60μW and 1.27μW. The corresponding lost rate of storage are 20% and 4.5% per year. 微量量热学 电池 自放电速率 microcalorimetry Battery Self-discharge rate 1988-02-01 2021-04-01 2
