The lead-acid battery is a kind of widely used commercial rechargeable battery which had been developed for a century. As a typical lead-acid battery electrode material, PbO 2 can produce pseudocapacitance in the H 2 SO 4 electrolyte by the redox reaction of the PbSO 4 /PbO 2 electrode.
Lead acid battery manufacturers apply this paste to a frame or grid structure that mechanically supports it. The electrolyte is then free to enter all the tiny holes in the sponge, thereby increasing the effective capacity of the battery. The negative and positive lead battery plates conduct the energy during charging and discharging.
The composition of the alloy was the same as the positive grid produced by gravity casting. The counter electrode, with an approx. five times greater area compared to the working electrode, was made of pure lead (99.98% Pb, Avantor). Preparation of positive electrodes for the capacity test consisted of three main stages.
The active mass was obtained from lead powder made in a Barton pot. XRD analysis of lead dust showed that the used material consisted of 71.4% α - PbO, 4.6% β - PbO, and 24.0% Pb, in relative percent. This composition confirmed that the physicochemical parameters were appropriate for use in the lead-acid battery industry.
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.
The growth of lead sulfate crystals on the surface of the electrode is supported by the high discharge rates of the battery [34, 35].

A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions take place at the electrodes:
Lead–acid batteries with electrodes modified by the addition of Ca also provide for higher currents or Cold Cranking Amps. These batteries require little or no maintenance. The disadvantage is poor high-temperature performance. The addition of antimony (chemical symbol Sb) improves the mechanical strength of electrodes, which is important for EV (electrical …
