摘　　要：在铅膏中添加4BS“晶种”和过硼酸钠,然后分别在55℃和83℃、相对温度98%条件下固化3 h,制成生极板。通过SEM、XRD分析,目视板栅腐蚀情况,测试装配样品蓄电池性能,得到的结果表明:83℃的固化条件有利于铅膏中四碱式硫酸铅的形成;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、低温起动能力和循环耐久Ⅱ性能。The raw plate was prepared by adding 4BS"crystal seed"and sodium perborate into the lead paste,and then curing for 3 h at 55℃and 83℃,respectively,at 98%relative temperature.The results show that the curing condition at 83℃is favorable to the formation of four-base lead sulfate in lead paste.The addition of 0.25%sodium perborate and 1%4BS"crystal seed"additive in the positive paste is conducive to improving the capacity of the battery,low temperature starting,cycling durabilityⅡperformance.
