Processes taking place in the paste of lead-acid battery plates
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

What causes a lead-acid battery to short?
Internal shorts represent a more serious issue for lead-acid batteries, often leading to rapid self-discharge and severe performance loss. They occur when there is an unintended electrical connection within the battery, typically between the positive and negative plates.
How does a lead-acid battery shed?
The shedding process occurs naturally as lead-acid batteries age. The lead dioxide material in the positive plates slowly disintegrates and flakes off. This material falls to the bottom of the battery case and begins to accumulate.
What causes lead-acid battery failure?
Nevertheless, positive grid corrosion is probably still the most frequent, general cause of lead–acid battery failure, especially in prominent applications, such as for instance in automotive (SLI) batteries and in stand-by batteries. Pictures, as shown in Fig. 1 taken during post-mortem inspection, are familiar to every battery technician.
How does corrosion affect a lead-acid battery?
Corrosion is one of the most frequent problems that affect lead-acid batteries, particularly around the terminals and connections. Left untreated, corrosion can lead to poor conductivity, increased resistance, and ultimately, battery failure.
Why does a lead-acid battery have a low service life?
On the other hand, at very high acid concentrations, service life also decreases, in particular due to higher rates of self-discharge, due to gas evolution, and increased danger of sulfation of the active material. 1. Introduction The lead–acid battery is an old system, and its aging processes have been thoroughly investigated.
What are the major aging processes of a battery?
The anodic corrosion, positive active mass degradation and loss of adherence to the grid, irreversible formation of lead sulfate in the active mass, short circuits and loss of water are the major aging processes. The overcharge of the battery lead to accelerated corrosion and also to accelerated loss of water.
