摘要
Abstract
The self-discharge performance,the discharge ability after long-term storage and the dis-charge performance at low temperatures of the compos-ite batteries were tested and studied.The characteris-tics and performance of lithium batteries and composite batteries were compared.The annual self-discharge rate of composite batteries at room temperature is 0.18％,which hardly affects their 10-year service life.After 180 days of normal use,the internal resistance of composite batteries does not significantly increase;After being placed for 2 years,the battery voltage still meets the requirements for the use of intelligent gas meters,with almost no passivation phenomenon.Compared with lithium batteries,composite batteries have better performance in self discharge,passivation and low tem-perature resistance,which can better support the use of intelligent gas meters in a wider temperature range and longer life cycle.关键词
