Electric storage battery grids
摘要:
An electric storage battery grid made from an antimonial lead alloy containing 0.002 percent to 0.5 percent of selenium with 0.25 percent to 0.5 percent arsenic and up to 4.0 percent antimony is disclosed. The alloy has improved casting properties for making the grid and the grids have a reduced tendency to release antimony in use.
