摘要
从铅酸电池结构入手,结合电池的电化学反应,分析正极腐蚀增长导致端盖开裂的机理和原因。就预防因正极腐蚀增长引起的端盖开裂,提出裂纹临时黏合修复和整体更换的解决方案,以及在设计过程中通过加强极板机械强度和端盖材料强度、增设极板缓冲装置等措施。在后期维护过程中,通过加强电池组月度检查和年度充放电试验等措施,延缓或避免电池组端盖开裂的缺陷发生。
Based on the analysis of the structure of lead-acid battery and the electrochemical reaction of lead-acid battery,the mechanism and causes of the cracking of the end caps caused by the corrosion elongation of the cathode were analyzed,some preventive measures were put forward to prevent the cracking of the cover caused by the growth of the corrosion of the cathode,such as temporary repair by bonding or overall replacement.Besides,some ways were proposed to delay or avoid the occurrence of defects in the battery cover cracking,such as strengthening the mechanical strength of the plates and the cover materials,as well as adding plate cushioning devices were used during the design process.When maintenance,strengthening the battery pack monthly inspection and annual charging were always focused by the engineers.
