摘　　要：选取3种不同的炭黑作为负极添加剂,制备2 V/4 Ah的AGM单体电池,探讨了羧基官能团及其粒径对负极性能的影响。研究发现,羧基有利于提高负极活性物质利用率与低温大电流放电性能,而炭黑粒径分布则会影响负极板的充电接受能力与HRPSoC寿命。In this paper,we choose three kinds of carbon black as the negative electrode additives to prepare2V/4Ah AGM batteries.The effects of carboxyl as surface functional group and particle size of carbon black on the negative performance are discussed.The results show that the carboxyl group can improve the utilization of negative active materials and the low-temperature and high rate discharge performance under cold conditions.Meanwhile,the smaller particle size can affect the charging capacity and HRPSoC life of the negative plates.
