Abstract: A composition-of-matter comprising a plurality of particles is disclosed herein, the particles comprising a substance reversibly releasing an alkali metal while decreasing in volume and absorbing the alkali metal while increasing in volume. Some or all of the particles are encapsulated within a volume enclosed by a shell or matrix which conducts cations of the alkali metal, wherein a volume of the substance upon maximal absorption of the alkali metal does not exceed the volume enclosed by a shell or matrix. Further disclosed herein is a process for preparing a composition-of-matter by coating particles comprising the aforementioned substance with a conductor of cations of the alkali metal, when the substance is saturated with the alkali metal, as well as electrochemical half cells and batteries including the composition-of-matter.

Abstract: A double-layer capacitor (DLC) (10), including an electrolyte (20) having an electrochemically active species (28) dissolved therein. The electrochemically active species consists of a material that undergoes oxidation at one electrode and undergoes reduction at another electrode during charge and discharge processes of the DLC. The DLC also includes first and second electrodes (12, 14), consisting of a porous material (18, 26) in contact with the electrolyte. There is a porous separator (16) in the electrolyte separating the first electrode from the second electrode.

Abstract: A composition-of-matter comprising a plurality of particles is disclosed herein, the particles comprising a compound (e.g., an element or a mixture of elements) which forms an alloy with an alkali metal and/or an alloy of an alkali metal with said compound. The alloy is characterized by reversibly releasing the alkali metal and absorbing the alkali metal. Some or all of the particles are encapsulated within a volume enclosed by a shell or matrix which conducts cations of the alkali metal, wherein a volume of the alloy upon maximal absorption of the alkali metal does not exceed the volume enclosed by a shell or matrix. Further disclosed herein is a process of preparing a composition-of-matter, which is effected by coating particles comprising an alloy saturated with the alkali metal with a conductor of cations of the alkali metal, as well as electrochemical half cells and batteries including the composition-of-matter.

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.
