High-Temperature Curing of Lead-Acid Battery Positive Plates
This document summarizes research testing the curing of lead-acid battery positive plates at high temperatures. It finds that: 1) Curing positive plates at up to 65°C can reduce the curing time from 72 to 48 hours by enhancing processes like lead oxidation. 2) Above 65°C, the paste transforms from 3PbO-PbSO4-H2O to 4PbO-PbSO4, potentially reducing capacity. 3) The document

What causes sulphation in lead acid battery plates?
Also formation of the crystals on the plates interferes with electrolytic action which may become unequal on opposite sides of the plate resulting in buckling. Sulphation of the negative plate usually results from excessive local galvanic action. Undercharging of battery is the main cause of Sulphation in Lead Acid Battery plates.
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.
How do crystalline sulfates affect a battery?
These crystal sulfates attach themselves to the plates of the battery – specifically on the negative plate. They are small and harmless unless the battery is continually deprived of proper charging. When that happens, the lead sulfate becomes a stable crystalline deposit. This compromises the effectiveness of the battery in terms of capacity.
What causes stratification in a battery?
This is a conditions of high acid concentration at the bottom of the cell, and low concentration at the top. Stratification may be initiated by preferential discharge of the top portion of the battery, due to a lower ohmic resistance for current flow to upper part of the plates.
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.
Can crystallized ions be corrected by overcharging a battery?
If the crystallized ions in your battery are serviced early, they can be corrected by overcharging your battery. Overcharging, though, has its own costs. Hard Sulfation. This is when the crystallized ions are so great that the battery cannot be restored. This is when the battery is not charged properly for extended periods.
