TECHNOLOGY FOCUS - ELECTRONICS - Preferred Components: The electrode assembly has a first end portion and a second end portion, where the reinforcing material is adhered to the electrode assembly, and is adhered to at least one of the first end portion of the electrode assembly from which the electrode tabs extend and the second end portion of the electrode assembly is disposed in an opposite end to which the first end portion is disposed. The reinforcing material is adhered to the electrode assembly to surround sides of it. The first electrode plate, the second electrode plate, and the separator are configured to have different sizes so that an edge of the electrode assembly has a stair step configuration, and the reinforcing material covers the step-shaped edge of the electrode assembly. The edge of the electrode assembly is at least one of the first end portions of the electrode assembly from which the electrode tabs extend and the second end portion of the electrode assembly is disposed in an opposite direction to which the first end portion is disposed. The case is a soft pouch type.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The ceramic material is 25-80% of the reinforcing material. The reinforcing material comprises: 100 parts by weight or greater than or equal to 80 parts by weight of the polymer gel and 40-400 parts by weight, preferably100 parts by weight of the ceramic material. The ceramic material comprises at least one component comprising of aluminum oxide, titanium dioxide, barium titanate, silicon dioxide, magnesium oxide and zinc oxide.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The polymer gel is adhesive. The polymer gel comprises acrylate-based polymer or polyvinylidene fluoride-based polymer. The separator comprises at least one material comprising of polyethylene, polystyrene, polypropylene, copolymer of polyethylene and polypropylene and polyvinylidene fluoride-co-hexafluoropropylene copolymer, where the separator is manufactured by coating at least one material comprising of polyethylene, polystyrene, polypropylene, and copolymer of polyethylene and polypropylene with polyvinylidene fluoride-co-hexafluoropropylene copolymer.
