Abstract The chemistry system with graphite felt electrode and a single electrolyte, lead(II) in methanesulfonic acid was described in this paper. The effects of treatment methods on kinetics and cyclic voltammetry behavior of PbO2/Pb(II) couple were investigated. The results show that the equilibrium electrode potential PbO2/Pb(II) couple is 1.25 V and the PbO2/Pb(II) couple on graphite felt electrode has a good kinetics behavior. The cyclic voltammetry behavior of PbO2/Pb(II) couple on graphite felt electrode was investigated, and the oxidization and reduction peak potentials are 1.54V and 1.238V, respectively. The graphite felt treated with methanesulfonic acid, heat and both showed good electrocatalytic activity for PbO2/Pb(II) couple, and the treatment method with methanesulfonic acid is best.
