As already mentioned in the introduction the two phenomena which contribute to the aging of lead-acid battery in the SLI battery application are degradation and anodic corrosion. The modeling approach of these two effects has been discussed in the further part of this section. Anodic corrosion is an irreversible aging mechanism.
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.
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.
Europe took a different tack. The Eurobat Guide for the Specification of Valve Regulated Lead-Acid Stationary Cells and Batteries defines design life as follows: “The design life is the estimated life determined under laboratory conditions, and is quoted at 20°C using the manufacturer’s recommended float voltage conditions.” 6
The degradation of the active material in the lead-acid batteries consists of two main phenomena: 1) loss off contact between the grid and the active material and 2) sulfation. These two effects result in a capacity loss and an increase of the internal resistance, which is most notably under cycling operation.
In order to obtain the best service life, over-charge of batteries should be avoided, and charging should be carried out by appropriately limiting end-of-charge voltage. At the operating potential of the positive electrode, corrosion is accompanied by oxygen evolution.
