Title: Aqueous pyridinium cation-based redox flow batteries

Abstract

The present invention provides an aqueous redox flow battery comprising a negative electrode immersed in an aqueous liquid negative electrolyte, a positive electrode immersed in an 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 redox reactant. The negative redox reactant comprises a pyridinium compound of Formula (I) as described in the specification.
