Abstract: A flow battery includes a positive electrode, a positive electrode electrolyte, a negative electrode, a negative electrode electrolyte, and a polymer electrolyte membrane interposed between the positive electrode and the negative electrode. The positive electrode electrolyte includes water and a first redox couple. The first redox couple includes a first organic compound which includes a first moiety in conjugation with a second moiety. The first organic compound is reduced during discharge while during charging the reduction product of the first organic compound is oxidized to the first organic compound. The negative electrode electrolyte includes water and a second redox couple. The second couple includes a second organic compound including a first moiety in conjugation with a second moiety. The reduction product of the second organic compound is oxidized to the second organic compound during discharge.

Abstract: An electrochemical device includes an electrolyte, a cathode contacting the electrolyte, and an oxygen evolution reaction (OER) electrode operating as an anode contacting the electrolyte. The OER electrode includes an iron-containing substrate and a layer that includes a metal-containing layer disposed over the iron-containing substrate. The metal-containing layer includes a metal and iron, the metal being selected from the group consisting of nickel, cobalt, manganese, and combinations thereof.
