摘要： 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.
