Document Type and Number:
Japanese Patent JP2012153897
Kind Code:
A
Abstract:
To provide an organic/inorganic composite porous separator (film) and a method for producing the same, and to provide an electrochemical device comprising the organic/inorganic composite porous separator (film).
The porous polymer film comprises (a) a polyolefin-based film substrate; and (b) an active layer formed by coating at least one region selected from a group composed of the surface of the substrate and a part of pores present in the substrate with a mixture of inorganic particles and a predetermined binder polymer, wherein the inorganic particles in the active layer are interconnected among themselves by the binder polymer, and interstitial volumes among the inorganic particles form a pore structure.
