Abstract
The present invention relates to a resin coated metal laminate comprising at least a sealant layer, a barrier layer, and a substrate layer in this order, wherein the barrier layer includes stainless steel having a thickness of 50 μm or less, the substrate layer includes a polyamide as a main component, a thickness of the substrate layer is thinner than a thickness of the barrier layer, and a maximum value of tensile strength in a tensile test of the substrate layer is 25 N/mm or more, as well as a battery package and a battery using the resin coated metal laminate.
Claims10
A resin coated metal laminate comprising at least a sealant layer, a barrier layer, and a substrate layer in this order, wherein
- the barrier layer includes stainless steel having a thickness of 50 μm or less,
- the substrate layer includes a polyamide as a main component,
- a thickness of the substrate layer is thinner than a thickness of the barrier layer, and
- a maximum value of tensile strength in a tensile test of the substrate layer is 25 N/mm or more.
A resin coated metal laminate comprising at least a sealant layer, a barrier layer, and a substrate layer in this order, wherein
- the barrier layer includes stainless steel, and
- exposure of a layer adjacent to the substrate layer associated with destruction of the substrate layer is not seen as a result of a rubbing test below:
- rubbing test:
- a test piece is prepared by folding the resin coated metal laminate into two so that a surface on a side opposite to a side of the substrate layer on which the sealant layer is provided becomes convex, an outermost surface of the twofold site of the test piece is contacted with a smooth side of a stainless-steel bar having a diameter of 1.5 cm, to arrange the test piece, and the test piece is rubbed by reciprocating the test piece 99 times a distance of one-way 10.0 cm in a longitudinal direction of the stainless-steel bar, while applying a load of 200 g to the test piece.
