When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate. After discharge, the concentration of sulfuric acid in the electrolyte is decreased, and results in the increase of the internal resistance of the battery.
Given the fact that for lead acid batteries, the electrodes are dipped inside the electrolyte, a change in the temperature of the electrolyte will easily be noticed on the negative plate since the anode is made up of metallic lead which is a good conductor of thermal energy.
3.3 Battery Self-discharge The lead acid battery will have self-discharge reaction under open circuit condition, in which the lead is reacted with sulfuric acid to form lead sulfate and evolve hydrogen. The reaction is accelerated at higher temperature. The result of self-discharge is the lowering of voltage and capacity loss.
In this paper, the impact of high constant charging current rates on the charge/discharge efficiency in lead acid batteries was investigated upon, extending the range of the current regimes tested from the range [0.5A, 5A] to the range [1A, 8A].
1. Construction of sealed lead acid batteries Positive plate: Pasting the lead paste onto the grid, and transforming the paste with curing and formation processes to lead dioxide active material. The grid is made of Pb-Ca alloy, and the lead paste is a mixture of lead oxide and sulfuric acid.
