Abstract:
An energy storage cell (20) including: an anode (40) formed of a molten alkali metal; an air cathode (60); and an electrolyte medium (50) located between the anode and cathode.
Abstract:
Methods for forming three-layer thin-film battery (TFB) structures by sequential electrophoretic deposition (EPD) on a single conductive substrate. The TFBs may be two-dimensional or three-dimensional. The sequential EPD includes EPD of a first battery electrode followed by EPD of a porous separator on the first electrode and by EPD of a second battery electrode on the porous separator. In some embodiments of a Li or Li-ion TFB, the separator includes a Li ion conducting solid. In some embodiments of a Li or Li-ion TFB, the separator includes an inorganic porous solid rendered ionically conductive by impregnation with a liquid or polymer. In some embodiments, the TFBs are coated and sealed with an EPDd PEEK layer.

Abstract:
A method, including placing a substrate of a battery in a bath consisting of a metal M chosen from a metal group consisting of Fe, Ni, Co, Cu, W, V, and Mn, an oxidant selected from an oxidant group consisting of oxygen and sulfur, and a polymer. The method also includes applying an electrical current so as to form on the substrate a metal M compound cathode having a nanoscale grain structure.
