Abstract: Provided is a Ni—Fe battery comprising an iron electrode which is preconditioned prior to any charge-discharge cycle. The preconditioned iron electrode used in the Ni—Fe battery is prepared by first fabricating an electrode comprising an iron active material, and then treating the surface of the electrode with an oxidant to thereby create an oxidized surface.

Abstract: Provided is a process for preparing an electrode comprising an iron active material. The process comprises first fabricating an electrode comprising an iron active material, and then treating the electrode with a gaseous oxidant to thereby create an oxidized surface. The resulting iron electrode is preconditioned prior to any charge-discharge cycle to have the assessable surface of the iron active material in the same oxidation state as in discharged iron negative electrodes active material.
