Abstract

Abstract: The influence of the content changes of graphite, activated carbon, carbon black, barium sulfate and lignin in the negative electrode of lead carbon on the battery performance was studied by orthogonal experimental method. The total content of graphite and activated carbon remained 1.5%, and the ratio of graphite and activated carbon was changed. The content of carbon black was 0~0.5%, barium sulfate was 0.6%~1.2%, and lignin was 0.15%~0.35%. The battery performance was evaluated by capacity test, low temperature performance test and cycle performance test. The experimental results show that the carbon black and lignin have more influence on the battery low temperature performance, do not contain carbon black and lignin content of 0.35% had the best performance in low temperature respectively. The content of carbon black and the ratio of the graphite and activated carbon have more influence on cell cycle performance, adding of carbon black was unfavorable to the cycle life, the best PSOC performance was obtained when the activated carbon and graphite were added at 1:1.

Key words: lead-carbon battery, orthogonal experimental, negative plate sulfation, low temperature performance, cycle performance
