Here's how it works : Figure A: Lead-acid batteries work by releasing energy through an interaction that occurs between the positive and negative lead plates and the lead sulfates in the electrolyte. Figure B: Sulfation buildup occurs as lead sulfates form on the battery plates during the normal charge/discharge cycles.
A typical lead acid battery cell has two plate types, one of lead and one of lead dioxide, both in contact with the sulfuric acid electrolyte as either a liquid, absorbed in a mat (AGM), or a gel.
Strip can be stored as coils and be used for any grid design, which can mean a lower inventory stock for battery manufacturers. The mechanical and chemical properties as dictated by the lead alloy grain structure can be manipulated by control of rolling pressures and degree of deformation.
Therefore, the recycling of waste lead batteries is very important for recycling lead resources and protecting the environment. The main composition in spent lead-acid batteries are lead alloy grids, lead pastes, waste acid and plastics.
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.
