Characterization of the Electrochemical Behavior of MnSO₄ with and without TiOSO₄ in H₂SO₄ Solution

An electrochemical characteristic evaluation of the Ti-Mn electrolyte system in sulfuric acid aqueous solution was conducted different concentrations with and without mixing TiOSO 4 MnSO for a redox flow battery application. The reaction mechanism Mn studied using cyclic voltammetry anodic voltage hold techniques. overall behavior can be described by oxidation 2+ to MnO 2 where 3+ is an intermediate species. As concentration increases, less formed on working electrode more solution; however, due instability solution, undergoes hydrolysis precipitate as MnOOH solution. addition 1 M suggested lower H + which increases amount lowers found electrochemically active if it deposited electrode.
