Pseudocapacitance Induced by Redox Couples

Pseudocapacitance can also be induced by a redox reaction in which both the reductant and oxidant are dissolved in the electrolyte. For a reversible redox reaction, the Nernst equation like Equations (3.1) and Equations (3.2) to (3.6) are all applicable. In this case. Equation (3.6) can be alternatively rewritten as
