Solid-state redox reactions, oxide cathodes

The rate of movement depends on every parameter acting on the electrochemical reaction taking place in the solid film. Both anodic and cathodic overpotentials have a strong influence on the redox kinetics [60,61 J. At constant overpotential, any increase in the electrolyte concentration (which is one of the chemical factors in the solid-state reaction) promotes an increase in the rate of movement [62]. The current density has a similar influence increasing current densities decrease the time required to cross over a constant angle [55] due to the increase in the concentration of oxidation centers in the polymer (the other chemical factor in the process).
