摘要： 本工作采用正交实验方法研究了石墨、活性炭、炭黑、硫酸钡与木素在铅炭负极中的含量变化对电池性能的影响，其中石墨和活性炭总含量保持1.5%，改变石墨活性炭的比例，炭黑含量取0~0.5%，硫酸钡含量取0.6%~1.2%，木素含量取0.15%~0.35%。通过容量测试、低温性能测试与循环性能测试对电池进行性能评估。实验结果表明，炭黑与木素对电池低温性能影响比较大，不含炭黑与木素含量为0.35%分别有最佳的低温性能。炭黑、石墨与活性炭的比例对电池循环性能影响比较大，添加炭黑对循环寿命不利，活性炭与石墨按1：1添加时部分荷电态循环性能最好。

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
