Abstract: An iron electrode and a method of manufacturing an iron electrode for use in an iron-based rechargeable battery are disclosed. In one embodiment, the iron electrode includes carbonyl iron powder and one of a metal sulfide additive or metal oxide additive selected from the group of metals consisting of bismuth, lead, mercury, indium, gallium, and tin for suppressing hydrogen evolution at the iron electrode during charging of the iron-based rechargeable battery. An iron-air rechargeable battery including an iron electrode comprising carbonyl iron is also disclosed, as is an iron-air battery wherein at least one of the iron electrode and the electrolyte includes an organosulfur additive.

Abstract: An organic flow battery having a positive electrode electrolyte containing organic compounds with extended conjugation and/or cyclic side chains is provided. The flow battery includes a positive electrode and a positive electrode electrolyte including first solvent and a first redox couple. The positive electrode electrolyte flows over and contacting the positive electrode. The first redox couple includes a first organic compound and a reduction product of the first organic compound. The flow battery also includes a negative electrode and a negative electrode electrolyte including a second solvent and a second redox couple. The negative electrode electrolyte flows g over and contacts the positive electrode. Typically, an ion exchange membrane is interposed between the positive electrode and the negative electrode Characteristically, the first organic compound resists crossover through the ion exchange membrane.

Abstract: A rechargeable battery includes an iron electrode comprising carbonyl iron composition dispersed over a fibrous electrically conductive substrate. The carbonyl iron composition includes carbonyl iron and at least one additive. A counter-electrode is spaced from the iron electrode. An electrolyte is in contact with the iron electrode and the counter-electrode such that during discharge. Iron in the iron electrode is oxidized with reduction occurring at the counter-electrode such that an electric potential develops. During charging, iron oxides and hydroxides in the iron electrode are reduced with oxidation occurring at the counter-electrode (i.e., a nickel electrode or an air electrode).

Abstract: A quinone derivative with a high redox potential that does not undergo Michael addition or proto-desulfonation. This molecule addresses the key issues faced with the positive side material of an aqueous all-organic flow battery. This new molecule is 2,5-dihydroxy-4,6-dimethylbenzene-1,3-disulfonic acid (or the disulfonate salt thereof). This quinone derivative offers good solubility, electrochemical reversibility, and robustness to charge/discharge cycling. Quinones with reduced crossover are also provided.
