摘　　要：研究了供电动自行车使用的 12V -6Ah、12V -12Ah、12V -17Ah和 12V -38Ah等多种规格的阀控式铅酸蓄电池的放电性能。采用 6V -6Ah电池测定了含不同添加剂的正极活性物质利用率及电池的容量保持能力。实验结果表明 ,某些碳素材料和硫酸钠等添加剂可以提高电极的活性物质利用率。其中容量为 12Ah以上的电池以 5h率电流放电时 ,其初始质量比能量达到 36 6～ 38 0Wh/kg。Several types of valve-regulated lead acid batteries(12V-6Ah、12V-12Ah、12V-17Ah and 12V-38Ah)for electric bikes were investigated.The utilization coefficient of the positive active material and the wet storage performance of the batteries containing various electrode additives were measured by using of 6V-6Ah batteries.The results showed that some conductive carbon materials and sodium sulphate could improve the utilization coefficient of the active material of positive electrode.For the 12V,12～38Ah batteries,the initial weight specific energy was 36.6～38.0Wh/kg measured at 5h discharge rate.
