Study on Kinetics Behavior of the Lead Negative Electrode in the Lead Acid Flow Battery

Abstract:

The chemistry system with negative graphite felt electrode and a single electrolyte, lead(II)in methanesulfonic acid, was described. The effects of treatment methods on kinetics and cyclic voltammetry behavior of Pb(II)/Pb couple were studied. The results show that the equilibrium electrode potential Pb(II)/Pb couple was -0.233V and the Pb(II)/Pb couple on graphite felt electrode had a good kinetics behavior. The cyclic voltammogram of graphite felt electrode showed that the oxidization and reduction peak potentials were -0.044V and -0.454V, respectively. The graphite felt treated with methanesulfonic acid had little oxidization and reduction peak potentials difference, and showed good electro-catalytic activity for Pb(II)/Pb couple.
