    摘要: In an exchange NMR measurement of a fluoride ion of an electrical storage device multilayer separator that comprises porous layer A which contains a polyolefin resin and porous layer B which contains inorganic particles, r(AB) satisfies the relationship: r(AB) ≥ 45 , where r(AB) is the ion transmission rate (%) between porous layer A and porous layer B in a mixing time of 100 ms.
