Antimony gives necessary mechanical strength and castability to the grids. Antimony content has definitive role in deciding the cycle life and self-discharge properties of the lead acid batteries (Brennan et al., 1974; Berndt and Nijhawan, 1976).
In lead-acid batteries, the active materials are lead dioxide (PbO2) in the positive plates and metallic sponge lead (Pb) in the negative plates. The amount of active material in a battery is generally proportional to the capacity that a battery can deliver.
A lead acid battery is a type of battery made up of plates of lead in a case filled with an electrolyte (dilute sulphuric acid). When this battery discharges, some of the lead from the plates combines with the electrolyte to form lead sulfate (PbSO 4), which builds up on the surface of the plates as crystals (as electrons leave the battery as electricity).
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.
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.
The name “antimonial lead” refers to binary lead alloys with 1-6% antimony, with the higher antimony alloys (i.e. those with >1% antimony) commonly being called “hard lead” in industry. While antimony increases the hardness of lead, it does so by impairing its malleability.

Effect of antimony on premature capacity loss of lead/acid batteries ...
The studies show that there is little lead sulfate in locations with much antimony, and that antimony-containing corrosion layers discharge with difficulty. With flooded-type batteries, experiments demonstrate that using a Pb-Sb alloy for the positive leady oxide material is an effective way to improve the cycle-life performance of positive ...

Antimony in the Lead‐Acid Battery
It is well known that antimony, which is alloyed in the grids of the lead-acid battery to improve their castability, corrosion resistance, and strength, affects the properties of the battery in various ways. Of particular interest is its apparent beneficial effect on the cycle life of the positive plate. It has been suggested that antimony is ...

Lead–Acid Batteries
Lead–acid batteries are comprised of a lead-dioxide cathode, a sponge metallic lead anode, and a sulfuric acid solution electrolyte. The widespread applications of lead–acid batteries include, among others, the traction, starting, lighting, and ignition in vehicles, called SLI batteries and stationary batteries for uninterruptable power supplies and PV systems.
