how to make paste for plates in lead acid battery

how to make paste for plates in lead acid battery

The holes of the grid are filled with a mixture of red lead and 33% dilute sulphuric acid. (Different manufacturers have modified the mixture). The paste is pressed into the holes in the plates which are slightly tapered on both sides to assist in retention of the paste. This porous paste allows the acid to react with the lead inside the plate,

Processes taking place in the paste of lead-acid battery

Jan 10, 2005· 1. Introduction. During the production of lead-acid batteries, when pasted and cured plates are soaked in H 2 SO 4 solution before formation, sulfuric acid reacts with the cured paste whereby the paste is sulfated. The reaction between H 2 SO 4 and the paste proceeds in a reaction layer between the zones of cured paste and sulfated paste. With the time of soaking, the reaction layer

LEAD ACID BATTERY FORMATION TECHNIQUES

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.

Processes taking place in the paste of lead-acid battery

The soaking procedure is a step in the technological process of production of lead-acid battery plates. Cured plates are left to stay in the formation solution on open circuit (i.e. soaked) for 1–4 h and after that the formation process starts. During soaking, the cured paste undergoes partial sulfation.
