Influence of Different Carbon Materials on Lead Acid Battery

摘要: 为了有效抑制负极板的硫酸盐化，常在铅酸蓄电池的负极材料中加入添加剂，以延长铅酸蓄电池在高倍率部分荷电状态下的循环寿命. 本文通过在铅酸蓄电池负极铅膏中添加一定量的5种不同炭材料，经和膏、固化等步骤制成不同炭材料掺杂的负极板并组装成蓄电池，对蓄电池的充放电性能及高倍率部分荷电状态下的循环性能进行了测试. 并利用BET、SEM测试对这5种炭材料的结构和形貌进行了表征分析. 结果表明，不同种类的炭材料对铅酸蓄电池的作用效果不同. 高比表面积、结构疏松多孔且含有大量微孔的多级孔炭材料可以在几乎不影响电池容量的情况下，大大提高铅酸蓄电池在高倍率部分荷电状态下的循环寿命. 实验结论能够更好的指导铅酸蓄电池炭材料的开发和选用.

Abstract: In order to suppress the sulfation of negative plate effectively, some additives are usually introduced into negative electrode of lead acid batteries. Through pasting and curing, the negative pastes with five different carbon materials are assembled into the batteries. Charge-discharge properties and high rate partial state of charge state (HRPSoC) cycle times are tested respectively. The carbon materials are characterized by BET and SEM. The result show that different kinds of carbon materials have different impact on lead acid battery. The hierarchical porous carbon contains a great deal of micropore with loose and porous structure and high BET surface area, which added cells exhibit remarkable improvement in the cycle performance compared to that of the conventional cells without carbon.-
