摘要:实验采用了3种不同粒径的红开作为铅酸蓄电池正极添加剂,正极材料中红丹的质量分数为 5%。通过粒径分布测试、理化分析、XRD测试、CV测试,以及试验电池的充电接受能力测试、初始容量测试和循环性能测试,研究了红丹添加剂对电泡性能的影响。结果表明,正极铅膏中添加较小粒径红丹的试验电池的化成效率、充电接受能力、初始容量和循环性能均最佳。XRD测试发现,添加最小粒径红丹的正极生板中3BS含量以及正极熟板中β-PbO2含量均最高,且高于未使用红丹添加剂的对照电池。CV测试发现,添加最小粒径红丹的电极可逆性最高。

Abstract: The effects of three kinds of red lead as positive additives with the content of 5 wt% on the performances of lead-acid batteries were studied by the test of particle size distribution, physical and chemical analysis, XRD, CV and charge acceptance, initial capacity and cycle performance of batteries in this paper. The results showed that the tested batteries added with the smallest size red lead in positive active material had the best performance in terms of formation efficiency, charge acceptance, initial capacity and cycle performance. XRD showed that both the content of 3BS in positive plate and the content of β-PbO, in positive green plates were the highest, and more than those of tested battery without red lead. CV showed that the reversibility of working electrode with the smallest size red lead was the best

料电池等产品,但是,铅酸蓄电池以其绝对的价格优势和安全性在竞争中屹立不倒。如何提高铅酸蓄电池性能,一般来说,通常有两个途径,一是改善产品配方,二是改进生产工艺。改善产品配方又分为三个方向,即正极添加剂、电解液添加剂和负极添加剂。电池容量通常是受正极制约的,因此使用正极添加剂是改善电池容量更有效的手段。红丹的主要成分为四氧化三铅,其具有的高氧化性
