Title:
LAMINATE FILM AND SEPARATOR FOR BATTERY AND BATTERY EACH USING THE SAME
Document Type and Number:
Japanese Patent JP2014180821
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a laminate porous film with little shrinkage at a high temperature and excellent in terms of heat resistance.SOLUTION: The provided laminate film includes: a porous substrate film 10 and a heat-resistant porous layer 20 including inorganic particles (A) 21 having particle diameters of 0.6-10 μm, inorganic particles (B) 22 having particle diameters of 0.1-0.5 μm, and a binder resin. The inorganic particles (A) 21 are integrated, in a mutually contiguous state, by the binder resin and are arrayed as a monolayer entity on the porous substrate film 10. The inorganic particles (B) 22 are filled into a space formed in-between the inorganic particles (A) 21 and the porous substrate film 10.
