摘要
极柱是铅酸蓄电池的重要组成部件,起着连接内部单体的作用.气孔缺陷会导致极柱有效承载面积减小,耐腐蚀性、大电流承载能力降低,严重时会导致电池失效.笔者从生产实际出发,分析了极柱气孔产生的原因,在确认气孔检测方法的前提下,从影响气体排出时间与效率的合金凝固时间、脱模剂类型、模具结构三个方面进行了验证对比,提出了改善铅酸蓄电池极柱气孔的方法.
Abstract
In the production process of lead-acid battery,the pole terminal is an important component,which plays the role of connecting the cells.The blow-hole will reduce the effective bearing area of the pole,reduce the corrosion resistance and large current bearing capacity,and even lead to battery failure in serious cases.Based on the actual production,the author analyzed and demonstrated the factors that cause the blowhole in the pole terminal.On the premise of confirming the blow-hole detection method,the alloy solidification time,release agent type and mold structure which affect the gas discharge time and efficiency were verified and compared.And,the methods to improve the blow-hole defect in the pole of lead-acid battery were put forward.
