THE MECHANISM OF THE DISCHARGE AND RECOVERY OF THE VANADIUM PENTOXIDE ELECTRODE,

Abstract

A study was made to determine if the mechanism of the discharge and recovery of the V2O5 electrode was analogous to that proposed by Coleman for the MnO2 electrode. The discharge and recovery of the V2O5 electrode, at moderate current densities and in solutions in the pH range from two to five, were found to resemble closely these processes in MnO2. The discharge consists of reduction of the V2O5 followed by the diffusion of the discharge product, presumably by the motion of protons and electrons, into the body of the solid. The recovery consists of the continued diffusion of the discharge product, without further reduction, which increases the activity of the vanadium pentoxide on the surface and hence increases the electrode potential.
