B.R.A. cells made using low-antimony lead alloys: Results of a six-year service trial experiment No. E/DN/C133 (TN-LON-4)

Two principal causes of failure of lead-acid cells, with grids made from antimonial lead are interlinked. Destructive positive grid corrosion takes place over a period of years and antimony, liberated by the corrosion reaction, contaminates the negative spongy lead, lowering its hydrogen overvoltage. The former process leads eventually to...
