Failure Analysis of Cast Lead–Antimony Battery Grids
as-cast Pb–Sb battery grids received from a local battery grid manufacturer (Century Engineering Industries). These grids were locally manufactured by smelting of lead battery scrap into lead bullions and then transformed into Pb–Sb ingots by re-melting. Grids were then gravity casted into the mold of required shape and dimensions. Distortion,

The grid wires around the current collection tab carry the high currents generated by the whole grid during battery discharge. Performance optimised grids reduce the resistance in the grid area around the current collection tab. The reduction in resistance ensures the fast delivery of the high currents required during the cranking phase.
What Is Continuous Casting?
Introduced into steel manufacturing the 1950s as an alternative to ingot molds, the continuous casting machine has now become a standard in premium battery grid production. Using a series of rollers and water-cooled molds, the process lessens the chance of impurities and provides better thickness ratios. To get a better idea of the continuous ...
