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.
The lead battery is manufactured by using lead alloy ingots and lead oxide It comprises two chemically dissimilar leads based plates immersed in sulphuric acid solution. The positive plate is made up of lead dioxide PbO2 and the negative plate with pure lead.
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.
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 .
For many years, the plates of lead/acid batteries have been produced from leady oxide, a mixture of finely divided lead (`free-lead') and lead monoxide.
A polymer is then added to the paste to bind the crystals together and to produce desired rheological properties in the paste. The paste having the polymer addition is then pasted onto a grid where the paste is dried to form a battery plate of the lead acid battery.
