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 plate for a battery container, and a battery container using the plated steel plate for a battery container.
- the inventors of the present invention have proposed a surface-treated steel sheet having a nickel-tin intermetallic compound formed on the surface thereof, in which the surface of the battery container is easily made uneven by the processing of (see Patent Document 1).
- graphite is dispersed and precipitated in the nickel plating formed on the surface of the steel sheet, thereby forming irregularities on the surface and exposing graphite particles having excellent conductivity to the surface, thereby forming a gap between the negative electrode active material and the surface of the battery container.
- the present inventors have also proposed a surface-treated steel sheet with reduced contact resistance (see Patent Document 2).
- Patent Document 1 Japanese Patent Application Laid-Open No. 07-300695
- Patent Document 2 International Publication No. WO00Z05437 pamphlet
- 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. It is an object to provide a pond container and a battery using the same.
- the plated steel sheet for a battery container of the present invention which solves the above-mentioned problems is a plated steel sheet for a battery container using a steel sheet as a substrate.
- An iron-nickel alloy layer, a nickel layer, a nickel-tin alloy layer, and a layer made of silver or a silver-containing alloy are formed in this order on the steel sheet on the side serving as the inner surface of the battery container.
- a plated steel sheet for a battery container (Claim 2);
- An iron-nickel alloy layer, a nickel-tin alloy layer, and a layer made of silver or a silver-containing compound are formed on a steel sheet on the side serving as the inner surface of the battery container in the order from the bottom to the bottom. (Claim 3),
- An iron-nickel alloy layer, a nickel-phosphorus alloy layer, and a layer made of silver or a silver-containing compound are formed in order from the lower side on the steel sheet on the inner side of the battery container, wherein (Claim 5)
- An iron-nickel alloy layer, a nickel layer, a nickel-cobalt-phosphorus alloy layer, and a layer made of silver or a silver-containing alloy are formed in this order on the steel plate on the side that is the inner surface of the battery container.
- a plated steel sheet for a battery container (claim 6),
- An iron-nickel alloy layer, a nickel-cobalt phosphorus alloy layer, and a layer made of silver or a silver-containing compound are formed in this order on the steel sheet on the side serving as the inner surface of the battery container. It is a plated steel sheet for a battery container (claim 7).
- the layer composed of silver or silver-containing conjugate has an amount of 0.05-0.5 g / m 2 as silver. (Claim 8).
- the plated steel sheet for a battery container of the present invention is the plated steel sheet for a battery container according to any one of the above (claims 18 to 18), wherein iron-nickel alloy is sequentially applied to the steel sheet on the outer surface side of the battery container. A gold layer and a nickel layer are formed (claim 9).
- the battery container of the present invention is a battery container obtained by forming the steel sheet for battery container according to any one of claims 11 to 19 into a bottomed cylindrical shape. ).
- the battery of the present invention is a battery (claim 11) using the battery container according to the above (claim 10).
- a trace amount of silver or a silver-containing layer is formed on the outermost surface of the plated steel sheet for a battery container on the inner surface side of the battery container, so that the graphite powder is formed on the inner surface of the container. Even without using a paint containing as a main component, a discharge characteristic equal to or higher than that of a battery using a container coated with graphite in a conventional battery container can be obtained.
