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.
During the past several years extremely corrosion-resistant positive grid materials have been developed for lead acid batteries. These alloys consist of a low calcium content, moderate tin content, and additions of silver. Despite the high corrosion resistance these materials present problems in battery manufacturing.
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.
In order to avoid the described problem, valve-regulated lead–acid batteries are often maintained at an excessively high float voltage, again with correspondingly adverse effects on grid corrosion, as already mentioned.
The lead–acid battery is an old system, and its aging processes have been thoroughly investigated. Reviews regarding aging mechanisms, and expected service life, are found in the monographs by Bode and Berndt , and elsewhere , . The present paper is an up-date, summarizing the present understanding.
