1.硫酸盐化是硫酸铅在极板活性物质的孔隙中形成，团聚长大并沉积在表面形成类似盐一样的白色颗粒状态。硫酸铅一旦达到盐化状态，其在充电时难以转化成活性物质,导致不可逆容量损失；

Sulfation is the formation or deposit of lead sulfate on the surface of plates like a salt. If the sulfation becomes excessive and forms large crystals on the plates, the battery will not operate efficiently and may not work at all.

2.蓄电池硫酸化的常见原因是长时间处于过放电状态、工作温度过高和充电不足。Common causes of battery sulfation are rest long time in a discharged condition, operating at excessive temperatures, and under a prolonged undercharge state.
