うにして、機器類の小型化、軽足化に役立つ。2. Description of the Related Art In order to respond to the trend toward miniaturization and thinning of various electrical and electronic devices, thin batteries with a thickness of 1 s or less are preferably used. Typical thin batteries include MnO as the positive electrode.
2. Metal lithium or 1-i-A1 alloy is used as the negative electrode, and 1-iC,l) 04 is used as the electrolyte. ! There are flat, thin lithium batteries that use a non-aqueous electrolyte dissolved in a solvent. This flat thin lithium battery uses Fe as the bipolar current collector.
, AI, Nt, etc., and this current collector is also used as an exterior material, so it is not flexible. If a thin battery can be made flexibly, it can be bent and loaded into the internal space of electrical and electronic equipment according to its shape, which is advantageous for downsizing the equipment. For this reason, attempts are being made to develop flexible thin batteries. (Problems to be Solved by the Invention) An object of the present invention is to provide a flexible thin battery as one of such attempts. [Means for solving the problem] As shown in the drawings, the flexible thin battery of the present invention has the following features:
A heat-resistant and organic solvent-resistant plastic film 14 is placed on one side of the aluminum foil 13, and a heat-adhesive resin film 1 is placed on the other side.
2 are laminated together, and a metal thin film current collector 11 having leads 5 (6) is laminated on the latter, and two laminated materials 1 are placed facing each other, and between them, a positive electrode 3 and a separator impregnated with an electrolyte are formed. 2 and a negative electrode 4 are sandwiched and heat-sealed. A typical embodiment of the flexible thin battery of the present invention includes MnO2 as the positive electrode, Li as the negative electrode, and LiC as the electrolyte-impregnated separator! ! This is a thin lithium battery using a polypropylene nonwoven fabric impregnated with an electrolytic solution in which 04 is dissolved in propylene carbonate. The aluminum foil is used to prevent electrolyte leakage and provide moisture resistance to the battery, and in consideration of flexibility, the thickness is preferably about 7 to 20 μm. Heat-resistant and organic solvent-resistant plastic films are used to protect aluminum foil, and are typically made of plastics with a higher melting point than thermoadhesive resin films, such as polyester, nylon, polypropylene, and polycarbonate. The thickness is preferably about 8 to 40 microns. The thermoadhesive resin film is used to seal the battery by heat-sealing, and is required to be able to be thermally bonded to aluminum foil or a current collector, and to be stable with respect to non-aqueous electrolytes. As a material having such properties, it is preferable to use an ethylene-ethyl acrylate copolymer to which a carboxyl group, hydroxyl group, or acetoxy group is added by graft polymerization. In addition, ethylene-(meth)
Those that inherently have carboxyl groups in their molecules, such as acrylic acid copolymers and ionomers, saponified ethylene-vinyl acetate copolymers, polyethylene, polypropylene, ethylene-α-olefin copolymers, or ethylene-(meth) A methyl acrylate or ethyl ester copolymer graft-polymerized with maleic anhydride or the like to provide the above-mentioned functional groups can be used. The thickness of the film is preferably about 10 to 40 microns. To form a current collector with leads using a thin metal film, laminate a metal foil of nickel, stainless steel, or the like with a thickness of about 10 to 20 μm on a thermoadhesive resin film, provide a resist layer on top of it, and perform etching. After this, it is preferable to take a method of peeling off the resist layer. The aluminum foil and the heat-resistant, organic solvent-resistant plastic film can be easily bonded together using a urethane-based, polyester-based, or epoxy-based adhesive. The aluminum foil and the thermoadhesive resin film and the thermoadhesive resin film and the metal thin film can be laminated by thermal adhesion. [Function] The flexible thin battery of the present invention uses a flexible metal thin film as the current collector of both electrodes, and all other exterior materials are also flexible, so it can be bent into any shape. I can do it. The thermoadhesive resin film has excellent thermal adhesion to itself and to metals, so complete sealing can be achieved by heat sealing. [Example] A 12μ thick polyethylene terephthalate film was attached to one side of a 7μ thick A, ll foil using a urethane adhesive, and an ethylene-ethyl acrylate copolymer film was attached to the other side. Two films were prepared by thermally bonding a 30μ thick film and thermally bonding a 10μ thick Ni foil thereon. Next, we applied the thermosetting ink “Etching Resist X-77J”.
(Taiyo Ink Manufacture) was used to remove the N of one film.
A pattern of a current collector for the positive electrode is printed on one foil, and a pattern of a current collector for the negative electrode is printed on the Ni thin foil of the other film, along with the shape of the leads, and then heat cured to form an etching resist layer. Formed. The resist layer was removed by etching by immersion in a ferric chloride solution and cleaning with a caustic soda solution, thereby producing a laminated material in which a current collector having positive and negative electrode leads was formed. Using this laminated material, a flexible thin battery having the structure shown in the drawings was manufactured. A polypropylene nonwoven fabric was used as a separator, and Li CD was used as an electrolyte.
It was impregnated with a solution of O4 in propylene carbonate. MnO2 was used for the positive electrode, and li foil was used for the negative electrode. This flexible thin battery is extremely flexible,
The performance of the battery was also the same as the conventional one. Effects of the Invention The flexible thin battery of the present invention is extremely flexible and can be bent and loaded into the internal space of an electric/electronic carrier according to its shape. Of course, it can also be used by pasting it on the outside of the device. In this way, it helps to make equipment smaller and lighter.
