In order to control water losses and gassing in a lead-acid battery prone to antimony poisoning it is essential to break the antimony vicious cycle. This can be efectively done by blocking the hydrogen evolution reaction with inhibitors that would deactivate the areas of the electrode contaminated for instance with antimony.
In this paper, the governing equations of lead-acid battery including conservation of charge in solid and liquid phases and conservation of species are solved simultaneously during discharge, rest and charge processes using an efficient reduced order model based on proper orthogonal decomposition (POD).
Watering is the most common battery maintenance action required from the user. Automatic and semi automatic watering systems are among the most popular lead acid battery accessories. Lack of proper watering leads to quick degradation of the battery (corrosion, sulfation....).
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 electrochemical transport equations of lead-acid battery form a set of highly coupled non-linear partial differential equations (PDEs) containing non-linear source terms. Moreover, the system of equations is highly stiff and requires iterative methods to find the solution.
In this role the lead acid battery provides short bursts of high current and should ideally be discharged to a maximum of 20% depth of discharge and operate at ~20°C, to ensure a good cycle life, about 1500 cycles orthree to five years of operation .
