Abstract

Abstract: In order to improve the operational stability and life of the new substation engineering fixed valve-controlled lead-acid battery, the battery performance was analyzed by using the high current acceleration cycle test, disassembly test and flame retardant test. The results show that at 50 ℃ after 18 high-current charge and discharge cycles (time-consuming 10 d), the capacity holding rate is 80.22%, reducing from the initial 701.93 A·h to 563.12 A·h, and the battery internal structure is still maintained. It is shown that the high temperature and high current circulation charge and discharge test can quickly destroy the internal structure and thus reduce the capacity. The research results can be used as a new test method and exploration for rapid evaluation and analysis of the performance and life of lead-acid batteries, and provide a basis for battery quality assessment.

Key words: battery, high current acceleration, disassembly, flame retardant
