Document Type and Number:
WIPO Patent Application WO/2019/130994
Kind Code:
A1
Abstract:
A separator for non-aqueous secondary batteries, comprising: a porous base material; a heat-resistant porous layer which is provided on one surface or both surfaces of the porous base material and has a porous coating film containing at least one compound selected from the group consisting of a wholly aromatic polyamide, polyamideimide and polyimide; and an adhesive layer which is provided on one surface or both surfaces of a laminate composed of the porous base material and the heat-resistant porous layer and contains adhesive resin particles adhered onto the laminate. A separator for non-aqueous secondary batteries, comprising: a porous base material; a heat-resistant porous layer which is provided on one surface or both surfaces of the porous base material and contains at least one component selected from a heat-resistant resin having at least one of an amide bond and an imide bond in the molecule thereof and inorganic particles; and an adhesive layer which is provided on one surface or both surfaces of a laminate composed of the porous base material and the heat-resistant porous layer and contains adhesive resin particles adhered onto the laminate, wherein the peel strength between the porous base material and the heat-resistant porous layer is 5 to 75 N/m.
