摘　　要：通过对铅膏中添加4BS“晶种”添加剂和过硼酸钠,分别在55和83℃、98%RH、3 h的条件下固化后形成的生极板进行SEM分析、XRD分析、目视板栅腐蚀情况,并对装配样品蓄电池进行性能测试。结果表明:在83℃的固化条件利于铅膏中四碱式硫酸铅(4 BS)的形成;正极膏中加入0.25%过硼酸钠和1%的4BS“晶种”添加剂,有利于提升蓄电池容量、低温起动、循环耐久Ⅱ性能。By adding 4BS and sodium perborate to paste,and the plates cured at 55℃or 83℃,98%RH with 3 h were texted by SEM,XRD,grid corrosion and the performance of the sample batteris.It is found that:(1)the curing condition at 83℃is favorable for the formation of 4 BS in active materials;(2)the addition of 0.25%sodium perborate and 1%4 BS additives to the positive paste is beneficial to the improvement of battery capacity,CCA and cycle endurance Ⅱ performance.
