Porous film, secondary battery separator and secondary battery |
| abstract |
(Project) An object of the present invention is to provide a separator for secondary batteries that sufficiently exhibits the characteristics of the porous layer due to excellent adhesion between the porous substrate and the porous layer and has excellent battery characteristics at low cost. (Solution) A porous layer comprising a heat-resistant resin having a melting point of 200° C. or higher or having no melting point is laminated on at least one side of the polyolefin porous substrate, and the porous layer has a porosity of 50% or more and 80% or less, and A porous film having a strength of 0.4 N/10 mm or more, wherein the strength of the porous layer is lower than the adhesion strength between the polyolefin porous substrate and the porous layer in a 180 degree peel test in the longitudinal direction. |
