Porous membrane, separator for secondary battery, and secondary battery |
| abstract |
An object of the present invention is to provide a secondary battery separator capable of sufficiently exhibiting the characteristics of the porous layer due to the excellent adhesion between the porous substrate and the porous layer at low cost, And has excellent battery characteristics. Porous membrane comprising a porous layer laminated on at least one surface of a polyolefin-made porous substrate, the porous layer containing a heat-resistant resin having a melting point of 200° C. or higher or no melting point, and the porous layer having a porosity of 50% or more and 80% or less, and the strength is 0.4 N/10mm or more, and the strength of the porous layer is lower than that of the porous base material made of polyolefin and the porous layer in the 180-degree peel test in the longitudinal direction. adhesion strength. |
