Abstract
Considering that battery separators will require further thinner materials and lower costs in the future, a multi-layer polyolefin porous membrane for laminating a modified porous layer, which has an exceptionally high peel strength to a modified porous layer, and is suitable for high-speed processing during slit process and battery assembly process, and a battery separator, on which the modified porous layer is laminated, is provided. A multi-layer polyolefin porous membrane comprising at least two layers; protrusions made of polyolefin satisfying µm < W < 50 p.m (where W is a protrusion size) and 0.5 um < H (where H is a protrusion height) and being irregularly disposed on one side of the multi-layer polyolefin porous membrane at a density of not less than 3 protrusions/cm and not more than 200 2 protrusions/cm 2 ; a meltdown temperature being not lower than 165°C; an air permeation resistance being not greater than 300 sec/100 cc Air; and a membrane thickness being not greater than 2011m.
