摘要： PROBLEM TO BE SOLVED: To reduce internal resistance of a battery, attain size reduction, increase capacity, and improve a rapid charge/discharge characteristic and charge/discharge cycle durability by forming a positive electrode body and/or a negative electrode body of a foaming metallic plate which does not form an allay with lithium or a metallic fiber sintered plate, and filling an electrode layer inside a metallic current collecting body. SOLUTION: A positive electrode body and/or a negative electrode body are integrally formed in a condition where a current collecting body three-dimensionally expands in a mixture by filling the mixture containing an active material and a polymer electrolyte in the current collecting body composed of a foaming metallic plate which does not form an alloy with lithium or a metallic fiber sintered plate. Therefore, an average distance between the active material and the current collecting body is small, and internal resistance of an electrode body is small. Therefore, a battery having large capacity is obtained, and can endure even large electric current discharge. In the electrode body, the active material is fixed by a polymer electrolyte also having a function as a binder together with the foaming metallic plate, and even if charge/ discharge is repeated, an increase in internal resistance of the electrode body can be restrained.

摘要： PROBLEM TO BE SOLVED: To realize an electronic product which is excellent in mechanical properties and resistance to thermal decomposition by a method wherein the electronic product is possessed of a thin film formed of triazine ring-containing fluorine polymer which is obtained by trimerizing the cyano group of a cyano group-containing fluorine polymer which contains a polymerization unit represented by a specific formula. SOLUTION: An electronic product is possessed of a thin film formed of triazine ring-containing fluorine polymer which is obtained by trimerizing the cyano group of a cyano group-containing fluorine polymer which contains a polymerization unit represented by a specific formula, CF2 -CF(A ) (wherein A denotes -OR CN, -CN, or -R CN; R is a polyfluoroalkylene group which may contain ether linkage and is possessed of carbons which are 1 to 15 in number). The thin film is made to serve as the buffer coating film of a semiconductor device, whereby the semiconductor device is improved in performance such as a reduction in signal transmission delay time by the excellent electrical properties of the thin film and enhanced in reliability by the excellent physical properties of the thin film in a high-temperature region.
