    摘要: An electrochemical battery cell (10) including a zinc electrode (20), and may be fabricated with an electrolyte (50) system including an electrolyte active species and a modifier. The electrolyte active species is typically a metal hydroxide such as KOH or NaOH, while the modifier may be a porphine such as a metal porphine, and/or a polymeric material. The polymeric material may be, for example, a polyvinyl resin such as polyvinyl alcohol or polyvinyl acetate. The resulting electrolyte typically includes between 3 and 10 weight percent of the polyvinyl resin, 5 and 50 weight percent of the metal hydroxide, and between 1 PPM and 1 wt % of the modifier. Employing such an electrolyte in a cell including a zinc electrode results in an energy storage device having improved power density and substantially longer cycle life.

    摘要: An electrochemical cell is provided with first (10) and second (11) electrodes and a solid polymer electrolyte (15) disposed therebetween. The electrodes include a current collecting layer, a layer of electrode active material, and a layer of an electrically conductive, polymeric protection material disposed therebetween. The protective layer protects, for example, the current collecting layer from the deleterious effects of the acid or alkaline electrolyte active species found in most electrochemical cells. The protective layer is formed of an intermetallic compound dispersed through a layer of appropriately chosen polymeric material.

    摘要: Electrodes for electrochemical capacitor are modified with a metal macrocyclic complex made up of phthalocyanine or porphyrin ligands bound to a transition metal to achieve improved conductivity, reversibility, and charge storage capacity. The electrode is formed from a metal base and coated with an oxide, nitride or carbide of a transition metal or with a conductive polymer. This coating is modified with the metal macrocyclic complex. Suitable metal macrocyclic complexes are iron phthalocyanine (FePc), iron meso-tetra(N-methyl-4-phenyl)porphyrin (FeTPP) or cobalt protoporphyrin (CoPP).
