| titleOfInvention | Separator for non-water-based secondary battery and non-water-based secondary battery |
| abstract | PROBLEM TO BE SOLVED: To provide a separator for a non-aqueous secondary battery in which curl deformation which impairs handleability at the time of battery production is suppressed. SOLUTION: A heat resistant resin layer containing at least one heat resistant resin selected from the group consisting of total aromatic polyamide, polyimide and polyamide imide is provided on one side of a porous base material, and the length of the mechanical direction MD is 1. .2 m, when the length of the TD in the width direction orthogonal to the MD is 60 mm, it has a shape that curls to the TD with the surface on the side opposite to the side provided with the heat-resistant resin layer of the porous substrate inside. It is a separator for a non-aqueous secondary battery in which the curl amount W (mm) in the above satisfies 0 <W ≦ 8 (W = 60 mm − W1) (W1: Separator piece in an environment of 25 ° C. and a relative humidity of 30%, a roller. When the coated surface of the porous substrate was brought into contact with two rollers arranged in parallel at an interval of 1 m and placed by applying a tension of 9.8 N / m, the separator piece was viewed in a plan view from the normal direction. TD projection width of the separator piece at the midpoint between the two rollers). [Selection diagram] None |
