POLYOLEFIN RESIN POROUS FILM, AND NON-AQUEOUS ELECTROLYTE CELL SEPARATOR USING SAME |
摘要 |
This polyolefin resin porous film can be easily produced, and when used as a non-aqueous electrolyte cell separator, can suppress clogging and can evince a high cell output. The polyolefin resin porous film is a porous film having a polyolefin resin as the primary component and is characterized by the average flow diameter pressure (P AP ) being 1500-2500 kPa, the bubble point pressure (P BP ) being 300-1500 kPa, and the ratio (Pa/P AP ) of the air permeability (Pa) and the bubble point pressure (P BP ) being no greater than 0.35 sec/(100 ml·kPa). |
