目前对正极添加剂使用方面相当慎重，成熟的发孔剂有SiO2、K2SO4海泡石粉（精制白蟹）等，一般用量0.02％-0.1％。导电剂有石墨、碳纤维等，用量在0.1%-0.3%范围。*新采用镀锡的微珠玻璃，既发孔又导电，效果显著。这些添加剂，特别是负极膨胀剂，其中有机膨胀剂在铅青中会对铅膏相组成产生影响。活性物质的脱落是可以抑制的，采用强化剂与完善固化工艺可以实现。但必须注意负极膨胀剂硫酸钡**不容许混人正极，因为PbO2的结构在硫酸钡存在下会迅速被破坏。
Use aspect equal circumspect to the cathode additive currently,the mature hair bore has SiO2, and the K2 SO4 sea bubble stonepowder(is refined white crab)...etc., general the dosage is0.02%-0.1%.Conduct electricity to there are graphite, and carbonfiber...etc., the dosage is in 0.1%-0.3% scopes.Lately adopttin-plating tiny bead glass, since the hair bore conductselectricity again, the effect shows Zhao.These additive, especiallyanode inflation, among them, the organic inflation is green in thelead in will mutually constitute creation influence to the leadcream.The sheding off of activity material can repress, theadoption enhances and perfect solid chemical engineering skill tocarry out.But have to notice an anode inflation the sulfuric acidbarium absolutely allow of no Xu Hun Ren's cathode, because thestructure of the PbO2 exists in the sulfuric acid barium under will be broken
