MULTILAYER POROUS MEMBRANE AND METHOD FOR PRODUCING THE SAME |
摘要 |
The present invention provides a multilayer porous membrane having both high safety and practicality, especially as a separator for a non-aqueous electrolyte battery and comprising a porous layer containing an inorganic filler and a resin binder on at least one surface of a polyolefin resin porous membrane, wherein the porous layer simultaneously satisfies the following (A) to (C):
(A) the inorganic filler has an average particle diameter of 0.1 µm or more and 3.0 µm or less,
(B) a ratio of an amount of the resin binder to a total amount of the inorganic filler and the resin binder is 1% or more and 8% or less in terms of volume fraction, and
(C) a ratio of a layer thickness of the porous layer to a total layer thickness is 15% or more and 50% or less. |
