Effect of Para-Dimethyl Aminobenzaldehyde additive on Electrochemical performance of Lead–Acid Battery

Abstract

Effects of para-dimethyl aminobenzaldehyde (p-DMAB) additive on electrochemical performance of lead-acid battery have been studied by electrochemical impedance spectroscopy (EIS), linear sweep voltammetry (LSV), cyclic voltammetry (CV) and scanning electron microscopy (SEM). Results show that p-DMAB improves the reduction and oxidation process of electrode materials, increases the hydrogen overpotential, facilitates the diffusion of substances into and out of the electrode. The p-DMAB additive is stable under the operating conditions of lead-acid batteries. The results showed that p-DMAB is promising for use as a suitable additive for lead- acid batteries.
