4 Frequently Asked Questions about “The role of antimony in lead-acid batteries”
How does antimony work in a battery?
However, the unavoidable corrosion of the positive grid liberates antimony out of the grid which acts in two different ways in the battery: on the one hand, antimony stabilizes the active material of the positive electrode.
What is lead antimony used for?
Due to the soft nature of pure lead, lead antimony alloys are used in the preparation of lead battery grids . Small amounts of elements like arsenic and selenium are usually added to the lead antimony alloys to improve the grain refinement, fluidity and age hardening of the grids.
What are the grids of lead-acid batteries made of?
Introduction The grids of lead-acid batteries are usually made of lead-antimony alloys containing 5 - 11 wt.% antimony. The necessary mechanical strength and castability are easily achieved with this content of antimony.
What is the effect of selenium on lead alloys?
A report is given on lead alloys which contain between 1 and 4% antimony and which are characterized by the addition of selenium. Using the selenium additive a very fine grain structure is achieved which improves castability and grid-quality to a great extent.
