Lead–acid batteries have been used as a practical power source for over 100 years because of their high performance, low cost, and safety. Great progress has been made since the appearance of the first lead–acid battery. More and more applications of lead–acid batteries will eventuate as the performance is improved further .
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.

The phenomenon called “sulfation” (or “sulfatation”) has plagued battery engineers for many years, and is still a major cause of failure of lead–acid batteries. The term “sulfation” described the condition of a battery plate, in which highly crystalline lead sulfate has formed in an practically irreversible manner.
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.
The lead-acid battery system is designed to perform optimally at ambient temperature (25°C) in terms of capacity and cyclability. However, varying climate zones enforce harsher conditions on automotive lead-acid batteries. Hence, they aged faster and showed lower performance when operated at extremity of the optimum ambient conditions.
Such batteries may achieve routinely 1500 cycles, to a depth-of-discharge of 80 % at C /5. With valve-regulated lead–acid batteries, one obtains up to 800 cycles. Standard SLI batteries, on the other hand, will generally not even reach 100 cycles of this type. 4. Irreversible formation of lead sulfate in the active mass (crystallization, sulfation)
