Abstract: Iron electrode materials, iron electrodes, and methods for fabricating said iron electrode materials and iron electrodes via elevated temperature thermomechanical processing of porous particulate iron materials are described. For example, as part of iron electrode manufacture, a particulate iron material into an apparatus may be provided. In addition, pressure and/or heat may be applied to the particulate iron material in the apparatus for a time period to form an electrode having therein conductive connections between particles of the particulate iron material.

Abstract: Materials, designs, and methods of fabrication for iron-manganese oxide electrochemical cells are disclosed. In various embodiments, the negative electrode is comprised of pelletized, briquetted, or pressed iron-bearing components, including metallic iron or iron-based compounds (oxides, hydroxides, sulfides, or combinations thereof), collectively called “iron negative electrode.” In various embodiments, the positive electrode is comprised of pelletized, briquetted, or pressed manganese-bearing components, including manganese (IV) oxide (MnO2), manganese (III) oxide (Mn2O3), manganese (III) oxyhydroxide (MnOOH), manganese (II) oxide (MnO), manganese (II) hydroxide (Mn(OH)2), or combinations thereof, collectively called “manganese oxide positive electrode.” In various embodiments, electrolyte is comprised of aqueous alkali metal hydroxide including lithium hydroxide (LiOH), sodium hydroxide (NaOH), potassium hydroxide (KOH), cesium hydroxide (CsOH), or combinations thereof. In various embodiments, battery components are assembled in prismatic configuration or cylindrical configuration.
