The Reaction at the Iron Alkaline Electrode

Abstract

The discharged state of the iron (Edison) electrode in alkaline solution has been reported historically as a number of materials, usually as either or . Recent x‐ray crystallography data, obtained independently in the two laboratories represented by the authors, indicates the material to be or , depending on the conditions of discharge. X‐ray patterns were obtained by in situ techniques with electrodes cycled in sealed polyethylene bags, as well as with washed and dried active materials.
