The lead-acid battery electrolyte and active mass of the positive electrode were modified by addition of four ammonium-based ionic liquids. In the first part of the experiment, parameters such as corrosion potential and current, polarization resistance, electrolyte conductivity, and stability were studied.
This study involved the preparation of lead oxide paste for use in the production of lead-acid batteries. The paste was applied to the positive plates, and its performance effects were tested on the battery. Morphological and surface area analyses were conducted using SEM and BET, respectively, after the performance tests.
The growth of lead sulfate crystals on the surface of the electrode is supported by the high discharge rates of the battery [34, 35].
Moreover, the active material enhances the porosity and thus increases mass transport in the PAM. There are certainly several ways in which the discharge properties of lead dioxide electrodes may be modified such as improving the pathway to all areas of the active mass as the transition of PbO 2 into PbSO 4 continues.
One of them is the addition of a corrosion inhibitor. Substances such as H 3 PO 4, H 3 BO 3, and several surfactants were successfully applied in lead-acid battery (LAB) for this purpose [1, 15, 16]. Recently, it has been found that addition of ionic liquids also decreases the corrosion rate [17, 18, 19].
