This ITRI report has reviewed use of tin in lead-acid batteries, concluding that current estimated use may grow at around 2.5% to 2025, after which there is a high risk of substitution by lithium-ion and other technologies.
This paper aims to present an innovative method for the fire refining of lead, which enables the retention of tin contained in lead from recycled lead–acid batteries. The proposed method uses aluminium scrap to remove impurities from the lead, virtually leaving all of the tin in it.
Refining of Alloys with Low Tin Content The first series of tests was conducted for lead containing tin in amounts similar to the alloys used in battery manufacture. The tin content varied from 1.26% to 1.53%. However, the antimony and arsenic contents differed significantly, varying from 1.02–5.83% and 0.0004–0.188%, respectively.
An alternative way of refining lead is, therefore, proposed, taking into account the removal of harmful impurities without reducing the tin content. This will allow for the optimal use of the tin contained in secondary lead for the production of lead alloys with tin and other additives.
The proposed method of refining secondary lead offers the possibility of using the tin already contained in the lead alloy, significantly reducing its consumption for the production of lead alloys for the battery industry. Instead of pure aluminium, aluminium scrap can be used successfully, provided its composition is controlled.
Tests of the proposed alternative method of refining the lead–tin alloy were conducted in industrial conditions at the lead refining department of a lead–acid battery recycling company.

Lead-acid batteries use Lead and an acid electrolyte as major components hence the name. These batteries can be classified or distinguished by the electrolyte and their construction. The workings of these batteries are similar but their constructions are what differ. The broad categories are: 1. Flooded Lead-Acid Battery. In these battery types, the electrodes …
The use of lead calcium or pure lead grids in valve-regulated lead/acid (VRLA) batteries has been generally satisfactory, but one drawback of these materials is the unpredictable build-up of a passivation layer on the surface of the positive grid. In deep-cycling applications, this passivation layer can result in a rapid loss of discharge ...

Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions ...

Lead-acid batteries rely primarily on lead and sulfuric acid to function and are one of the oldest batteries in existence. At its heart, the battery contains two types of plates: a lead dioxide (PbO2) plate, which serves as the positive plate, and a pure lead (Pb) plate, which acts as the negative plate. With the plates being submerged in an electrolyte solution made from a diluted form of ...
