英文摘要: The kinetic characteristics of the concentrated V(IV)/V(V) couple have been studied at a glassy carbon electrode in sulfuric acid using rotating-disc electrode and cyclic voltammetry. The kinetics of the V(IV)/V(V) redox couple reaction was found to be electrochemically quasi-reversible with the slower kinetics for the V(V) reduction than that for the V(IV) oxidation. And, dependence of diffusion coefficients and kinetic parameters of V(IV) species on the V(IV) and H2SO4 concentration was investigated. It is shown that the concentration of active species V(IV) should be over 1 mol(.)L(-1) for the redox flow battery application. Further, with increasing the V(IV) and H2SO4 concentration, the diffusion coefficients of V(IV) were gradually reduced whereas its kinetics was improved considerably, especially in the case of V(IV) and H2SO4 up to 2 and 4 mol(.)L(-1).
