【発明の詳細な説明】 〔発明の技術分野〕 本発明は電池蓋を改良したボタン電池用電池に関する。[Detailed description of the invention] [Technical field of invention] The present invention relates to a battery for button batteries with an improved battery cover.

たものが多く用いられている。Conventionally, as shown in the figure, a core layer 1 made of stainless steel or mild steel has an outer layer 2 made of, for example, pure nickel, and an inner layer 3 made of pure copper or a copper alloy, for example, bonded to the inner surface. In many cases, a battery lid is formed by forming a three-layer cladding material and pressing the cladding material.

池蓋の外側の素材として好適であるという理由によるも
のである。This is suitable as a material for the inside of the battery lid because - is easy to amalgamate and has good electrical contact with the cathode active material 4, and stainless copper has high strength and is suitable as a reinforcing material. This is because pure nickel has good corrosion resistance and low contact resistance with external terminals, making it suitable as a material for the outside of the battery lid.

性が必要とされている。Then, bend the battery cover tightly around the periphery by approximately 180 degrees, and
Since it is formed by bending 90 degrees into steps and is press-fitted to the cylindrical case via a seal, the material needs to have high strength and elasticity.

充分となって電解液の漏れ等が生じることがあった。However, in recent years, there has been an increasing demand for batteries to be smaller, thinner, and have a longer lifespan, and therefore, consideration is being given to reducing the thickness of the battery lid. However, if the thickness of the pure nickel in the outer layer is made thinner, the hardness of Nikgal is low, so it is easily damaged, and if the core material is modified, its strength decreases, and the crimping with the cylindrical case becomes insufficient, resulting in electrolyte leakage, etc. Sometimes it happened.

の提供を目的とする。An object of the present invention is to provide a battery that has excellent strength and scratch resistance and can be made thinner.

とからその方法を採るのが望ましい。In manufacturing the battery according to the present invention, a two-layer crab material is used as a metal base, in which a core material made of stainless steel such as 5U8304 and an inner material made of a copper plate, etc. are crimped together, and the annealed crab material is pressed. The above-mentioned shield is coated on the stainless steel side of the post-clad material by a so-called PVD method such as chemical vapor deposition (abbreviated as plasma CVD) in a glow discharge space, ion blasting, sputtering, or the like. It is desirable that the metal substrate is composed of a core material having elasticity as described above and an inner material having excellent conductivity. Therefore, the inner material is preferably copper or a copper alloy. The core material may be any material that has the strength and elasticity to function as a lid, but stainless steel (13Cr-F
e, 18Cr-8Nl-Fa, etc.) satisfy this condition and can be used practically. In addition, if particularly strong strength is required, precipitation hardened steel is preferably used. Precipitation hardening steels include Cr-Mo type (1-2.5 Cr-0,4-0.
8 Mo-Fa etc.) and Ni-Cr type (17-4PH1l
d, 17-7PH class, etc.) are practical. Furthermore, among the methods for forming the surface layer, it is particularly desirable to use the plasma CVD method because it can easily provide a coated surface with uniform and stable gloss.

The substrate to be treated was placed as a cathode in a mixed gas atmosphere of metal halide and hydrocarbon gas (acetylene, methane, ethane, propane, etc.) at 10 Torr and heated at 100°C.
Heating to a temperature range of ~600℃, and heating to 200℃~
A voltage of 8 KV is applied to form a DC glow discharge space 6, and a carbide film is formed on the surface of the substrate to be treated. This reaction is, for example, T fish C14+ CH,→Ti
It is like C+ 4 HCl. Similarly, to obtain borides, a mixed gas of metal halides, boron chlorides, poron fluorides, etc. is used, and to obtain silicides, mixed gases of metal halides, silanes, silicon chlorides, etc. are used. .
