Thermodynamic and Kinetic Analysis of Electrolyte Properties

The properties of electrolytes affect both the mass transport and electrode reactions. The electrochemical stability of reactants is determined by the redox stability of the electrolyte. Accurate interpretation of electrode reaction scheme is essential for understanding reaction kinetics. Thermodynamic and kinetic properties lead to important characteristics in battery development, such as high-energy density and high-power density. This review presents three studies on analysis and analytical methods aimed at improving these properties: the relationship between the redox resistance of electrolyte and its concentration and pH, the measuring method for the local pH in the vicinity of the electrode, and the proposal of analytical method for the steady-state current-potential curve for oxygen reduction reaction.
