摘　　要：为降低ＰｂＯ２电极析氧过电位，本文对在有添加剂作用下的电解液及其所制备的ＰｂＯ２电极的性能进行了研究．结果表明：添加剂的加入，使电解液的分散能力提高，沉积层均匀、致密，在酸性介质中，由加有添加剂电解液制备的ＰｂＯ２电极一定程度降低了阳极析氧的过电位．文中还分析了所制备电极析氧过电位降低的原因．In order to decrease the overpotential for oxygen evolution reaction of PbO2 electrode. investigation of preperationof PbO2 electrode in electrolyte solution with the presence of additive and their perfomances were carried out. The results show that throwing power of electrolyte solution was moresed and the grain structure of the coating was signigicantly finer in electrolyte solution with the presence of additive.And the Pbi2 electrode can decrease the overpotential or oxygen evolution reaction to a certain degerade.The cause of decrease in overpotential for oxygen evolution reaction of the electrode is also discussed.
