Definitions
- Plated steel plate for battery container battery container using the plated steel plate for battery container, and battery using the battery container
- the present invention relates to a plated steel sheet for a battery container, a battery container using the plated steel sheet for a battery container, and a battery using the battery container.
- Patent Document 1 International Publication No. WO00Z05437 pamphlet
- Patent Document 2 JP 2002-180296 A
- Patent Document 3 Japanese Patent Application Laid-Open No. 2004-076118
- the present invention relates to a plated steel sheet for a battery container, which can provide a battery having excellent discharge characteristics without forming a conductive layer mainly composed of graphite or the like on the inner surface of the battery container, and an electrode using the same.
- An object of the present invention is to provide a pond container and a battery using the same.
- the plated steel sheet for a battery container of the present invention that solves the above-mentioned problems is characterized in that dispersed nickel and iron, in which fine carbonaceous material is dispersed in a layer, are sequentially placed on a steel sheet on the side of the steel sheet that is the inner surface of the battery container.
- a nickel-iron diffusion layer formed by diffusion, a nickel-tin diffusion layer formed by dispersing nickel and tin in which fine carbonaceous material is dispersed in the layer, and a layer formed of silver or silver-containing material are formed.
- carbon black and the Z or black ship are dispersed in an amount of 0.1 to 5% by weight in the nickel tin diffusion layer and the dispersed nickel layer (claim 6).
- the battery container of the present invention is a battery container (Claim 7) obtained by forming the steel sheet for battery container according to any one of the above (Claims 1 to 6) into a bottomed cylindrical shape. ) And
- the battery of the present invention is a battery (claim 8) using the battery container of (claim 7).
- the steel sheet used as the substrate may be a general-purpose low-carbon aluminum-killed steel (carbon content: 0.01 to 0.15% by weight) or a non-ageable ultra-low-carbon aluminum-killed steel (carbon content: 0.01% by weight) to which niobium or titanium is added. %).
- These steels are hot-rolled to remove the scale from the surface by pickling, then cold-rolled, electrolytically cleaned, annealed and temper-rolled, and used as a substrate. After cold rolling and electrolytic cleaning, the substrate may be plated without annealing and then annealed.
- a metal layer is formed on both sides of the steel sheet as the substrate obtained in this manner to obtain a plated steel sheet for a battery container of the present invention.
- the metal layer formed by plating and then performing diffusion heat treatment on the plating steel sheet for battery containers is a nickel plating layer, various nickel alloy plating layers, or a heat treatment after forming these plating layers on the steel sheet. And others.
- the outer surface of the battery container may be provided with a normal nickel plating layer, various nickel alloy plating layers, or a layer formed by forming these plating layers on a steel plate and then performing heat treatment.
