摘要：铝炭超缓电池由于具有高功率、长寿命等优点而被广泛关注，并被研完应用于混合动力汽车。本文通过循环伏安、SEM测试对铅炭负极板进行了研究，同时制备铅炭超级电池进行循环寿命测试。结果显示，炭材料加入到常规动力蓄电池负极活性物质中，可以增强负极板的电容特性。由于炭材料颗粒细小，可以细化硫酸铅颗粒，抑制负极硫酸盐化，显著延长电池在 HRPSoC条件下的循环寿命；同时，炭材料还可起“储酸器”的作用，提高电池的放电电位，
降低充电过电位；但炭材料的加入会加快负极的析氢速率。关键词：铝炭超级电池，HRPSoC，炭材料；硫酸盐化

Abstract: The Pb-C ultra-batteries received extensive concern for it has the advantages of high power, long life, etc, and it had been used in hybrid-electric vehicles. The Pb-C negative plates had been studied through CV and SEM in this paper, and the cycle life test of the Pb-C ultra-battery had been conducted. The results showed that the capacitance characteristics of the negative plates could be enhanced for the carbon materials were added to the conventional negative active materials.Because carbon materials were fine, the lead sulfate particles could be smaller, the sulphation of negative plate was inhibited, and the cycle life of the battery was significantly extended under the conditions of HRPSoC. The carbon materials also could play the role of "acid reservoir" to improve dischargo potential, reduce the charge potential. But the addition of the carbon materials will accelerate negative hydrogenevolution rate.
Key words: Pb-C ultra-battery; HRPSoC; carbon material; sulphation

面积炭材料的导电性和对铅基活性物质的分散性以及电容特性，抑制硫酸铅结晶的长大和失活。铅炭电池中炭材料的双电层电容所起的作用与“内并” 铅酸超级电池类似，因此，也被称之为“第二代铅酸超级电池”[1-3】（或“内混”超级电池）。因为铅炭电池克服了常规铅蓄电池在部分荷电状态、高倍率充放电条件下充放电功率低、易硫酸盐化、寿命短等问题，所以成为混合动力汽车的最佳辅助动
