In article number 1702056 Roy G. Gordon, Michael J. Aziz and co‐workers, introduce an aqueous flow battery based on low‐cost, nonflammable, noncorrosive, and earth‐abundant elements. During charging, electrons are stored in a concentrated aqueous solution of 2,5‐dihydroxy‐1,4‐benzoquinone, which rapidly receives electrons from inexpensive carbon electrodes without the assistance of any metal electrocatalyst. Electrons are withdrawn from a second aqueous solution of a food additive, potassium ferrocyanide.
