摘要
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 Electrons are withdrawn from a second aqueous solution of a food additive, potassium ferrocyanide.
