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 translation: 可再充电电池包括分散在纤维状导电性基材上的羰基铁组合物的铁电极。 羰基铁组合物包括羰基铁和至少一种添加剂。 对电极与铁电极间隔开。 电解液与铁电极和对电极接触，使得在放电期间。 铁电极中的铁被氧化，在对电极处发生还原，使得电位发生。 在充电期间，铁电极中的铁氧化物和氢氧化物在反电极（即，镍电极或空气电极）处发生氧化而减少。
