1. A plate making process for a lead acid battery comprising adding a polymer to a paste comprising basic lead sulfate crystals of desired crystal morphology to bind the crystals together and pasting the polymer-containing paste onto a grid where the paste is dried to form a battery plate of the lead acid battery. 2.
In the manufacture of lead-acid batteries, there are two key processes that cause changes to the chemical composition of the active materials, namely, curing (sometimes referred to as hydrosetting) and formation. Curing is the process that is vital to making plates of good quality that will ensure reliable battery performance .
The paste from the extrusion apparatus is extruded into the grid mesh, where the paste is dried to form a battery plate of the lead-acid battery. The extruding step can be performed as a sheathing process, a roll-forming process, a tape-casting process, or an injection molding process.
The initial formation charge of a lead-acid battery, whether in the form of plates or as an already assembled battery, is quite a complex bundle of chemical reactions. It is important to know in principle about the most important parameters controlling this process in order to achieve good reproducible results with reasonable efforts.
Making a lead paste with qualified lead powder, diluted sulfuric acid, and additives is the first step in the production of paste-coated plates. The second step involves spreading the lead paste on the grid with a smear machine or by hand. The third step involves solidifying and drying the filled plate to produce an unformed plate. 4.
The electrolyte in a lead-acid battery is a solution of sulfuric acid, while the electrodes are mostly constructed of lead and lead oxide. Positive plates of lead-acid batteries that are discharged primarily contain lead dioxide, while negative plates primarily contain lead.
Battery companies have had to modify their curing practice to assure satisfactory reduction in free-lead in the final plates. Free-lead in the formed plates can lead to …
