Organic non-aqueous cation-based redox flow batteries

Title: Organic non-aqueous cation-based redox flow batteries

Abstract

The present invention provides a non-aqueous redox flow battery comprising a negative electrode immersed in a non-aqueous liquid negative electrolyte, a positive electrode immersed in a non-aqueous liquid positive electrolyte, and a cation-permeable separator (e.g., a porous membrane, film, sheet, or panel) between the negative electrolyte from the positive electrolyte. During charging and discharging, the electrolytes are circulated over their respective electrodes. The electrolytes each comprise an electrolyte salt (e.g., a lithium or sodium salt), a transition-metal free redox reactant, and optionally an electrochemically stable organic solvent. The redox reactant of the positive electrolyte is a dialkoxybenzene compound, and the redox reactant of the negative electrolyte is a viologen compound or a dipyridyl ketone.
