<P>PROBLEM TO BE SOLVED: To provide a laminated material which excels in vibration resistance when used as a container or a sheath material for a secondary battery and therefore does not contaminate the electrolyte with lubricant, and to provide a secondary battery container using the same. <P>SOLUTION: A laminated material comprises: a film (A) comprising polyethylene terephthalate, polyethylene naphthalate or polylactic acid; a nylon 6 film (B); an aluminum foil (C); and a polypropylene film (D), which are laminated in that order. In the A/B/C/D laminated material, the B and D are non-oriented film, and a modified polyolefin layer is provided between the C and the D, and the D contains 0.1 to 20 wt. ppm of at least one kind selected from erucic acid amide, oleic acid amide, stearic acid amide, and ethylene bis-oleic acid amide. A method for manufacturing secondary battery container involves fitting a cover film (E) on a D side surface of the A/B/C/D laminated material to form a secondary battery container. <P>COPYRIGHT: (C)2012,JPO&INPIT |
