摘要
负极汇流排腐蚀及脱落 (NGBC :NegativeGroupBarCorrosion)是造成VRLA电池失效的一个重要原因。本文阐述了负极汇流排腐蚀及脱落的电化学机理 ,通过对机理的研究证明 :提高焊接区域的质量 [包括使用铸焊 (COS)
A corrosive attack lug/top bar area was an important reason that caused the failure of the negative plates of valve regulated lead/acid batteries.The phenomenon and electrochemical mechanism of NGBC of VRLA batteries were discribed.As aremedy,a good top bar/plate group technique for welding(includes COS),reduced remarkably the risk of any corrosion in this part of battery.
