Document Type and Number:
Japanese Patent JP6205375
Kind Code:
B2
Abstract:
The invention relates to a biaxially oriented, single or multilayer porous film comprising at least one porous layer, said layer containing at least one propylene polymer, wherein (i) the porosity of the porous film is 30% to 80%, and (ii) the permeability of the porous film is <1000 s (Gurley value). The invention is characterized in that (iii) the porous film is provided with a partially inorganic, preferably ceramic lamination, and (iv) in that the laminated porous film has a Gurley value of <1200 s. The invention further relates to a method for producing such a film, and to the use thereof in high-energy or high-performance systems, in particular in lithium batteries, lithium ion batteries, lithium polymer batteries, and alkaline earth batteries.
