EXAMPLE - An electrolyte liquid (in mg) (140) consisting of an ethylene carbonate/diethyl carbonate mixed solution containing 1 mol/l of a lithium hexafluorophosphate (LiPF6) electrolyte salt and a vinylidene-fluoride-hexafluoropropylene copolymer (X) (60) in an argon atmosphere, was placed in a dry box equipped with a gas purification apparatus. Then, 1.2 g of tetrahydrofuran was added to obtain a tetrahydrofuran solution of a gel electrolyte. Subsequently, the gel electrolyte (200) was mixed with a compound of formula (101) (31) and an ion electroconductive adjuvant, and then stirred for 3 minutes, until tetrahydrofuran (1 g) was added and the whole solution became uniform, to obtain a black slurry.    The obtained slurry (200) was dropped to an aluminum foil surface equipped with a lead wire, and expanded until uniform thickness was obtained, left for 120 minutes at room temperature and then tetrahydrofuran was vaporized, to obtain an organic compound layer containing compound (101) on the aluminum foil.    To an electrolyte liquid (1400) consisting of an ethylene carbonate/diethyl carbonate mixed solution containing 1 mol/l of LiPF6 electrolyte salt and a copolymer (X) (600), tetrahydrofuran (11.3 g) was added and stirred at room temperature. After the dissolution of the copolymer (X), the solution was applied on a glass plate of thickness 1 mm and left for 1 hour. The tetrahydrofuran was dried naturally to obtain a gel electrolyte film having a thickness of 150 mum on the glass plate. The obtained gel electrolyte film was cut into 2 x 2 cm and then deposited on the obtained aluminum foil which had the organic compound layer. Subsequently, a lithium layer or a copper-foil equipped with a lead wire was overlaid. The obtained laminated component was sealed by inserting the component into a polytetrafluoroethylene sheet having a thickness of 5 mm, and then a pressure was applied, to produce a battery. The battery had a spin concentration of anode layer of 2.3 x 10(20) spin/g, and excellent charging and discharging property.
