Low-antimony lead-alloy expanded grids: preliminary performance data

Low-antimony lead alloys have been successfully produced by a unique continuous casting process. The alloys contain 1 to 3 wt.% antimony, 0.01 to 0.20 wt.% arsenic and 0.2 to 0.3 wt.% tin. Battery grids fabricated from these alloys are found to have electrochemical properties that are superior to those of conventional gravity-cast, low-antimony, lead-alloy grids. Preliminary results are presented.
