TECHNOLOGY FOCUS - POLYMERS - Preferred Components: Matrix (A) may also contain a plasticizer and/or a solvent or swelling agent. (A) may consist of or contain crosslinkable, liquid or soft addition polymers or condensation resins, especially aminoplastics, phenolic resins, epoxy resins, polyesters, polycarbonates and methyl methacrylate reaction resins, or natural or synthetic polymers or mixtures thereof, especially polysaccharides, proteins, resins, waxes, optionally halogenated rubbers, thermoplastics and thermo-elastomers. Polymers in (A) may be at least partly dissolved or swollen in a solvent or swelling agent and the matrix may also contain a hygroscopic salt.Preferred Composition: Layers based on this paste are flexible layers. Laminates as in (b) and (c) above have further layers acting as lower and upper conducting electrodes on the layers with positive and negative electrode materials respectively. A thin layer of plastic may also be present between these further layers and one or both of the layers with electrode materials; this plastic layer contains conductive metals or their alloys suitable for transporting electrons from the electrode material to the corresponding conducting electrode.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: Liquid (B) comprises substances which are suitable as positive or negative electrode materials, electrolytes or ionic or electronic conductors between two such adjacent substances or materials in an electrochemical component. (B) is a water-containing or anhydrous, essentially inorganic liquid containing undissolved solid electrolytes and/or a mixed conductor and/or electrolyte material, preferably consisting of or containing magnesium chloride, vanadium oxyhalide, aqueous or anhydrous sulfuric acid, potassium hydroxide solution or LiAlCl4/SO2. (B) may also contain a hydrophilic organic additive, preferably an alcohol. Solid (C) is silicon dioxide, silicon nitride, aluminum oxide, aluminum nitride, magnesium oxide or a mixture of these. The cathode material in laminates (b) and (c) above is a salt, preferably a lithium salt dissolved in a proton-releasing solvent, preferably water, and the anode material is an aprotic material. EXAMPLE - A mixture of 1 g PVDF-HFP copolymer, 1.5 g dibutyl phthalate and 10 g acetone was mixed with 7 g zinc powder to form an anode material. A similar polymer mixture was combined with 5 g silica to form an electrolyte material, or with 7 g manganese dioxide to form a cathode material. The two electrodes and the electrolyte were formed into tapes, then the acetone was evaporated and the plasticizer was leached out with hexane. The tapes were filled with a solution of potassium hydroxide in aqueous alcohol (1:1) and pressed between two stainless steel electrodes to form a primary battery.
