Electrochemical Properties of Organic Disulfide/Thiolate Redox Couples

The redox behavior, kinetic reversibility, chemical reversibility and stability, and the specific adsorption or chemisorption at electrode surfaces of a diverse group of organodisulfide cathode materials have been studied by potential‐sweep and potential‐step methods. The number of electrons involved in the redox reaction and the diffusion coefficients of the organodisulfide species in electrolyte solutions were determined with a rotating disk electrode in conjunction with chronocoulometry/chronoamperometry. Observations indicated that the overall, stoichiometric reaction of these redox couples is
