Laminated porous film, battery separator and battery using the same |
abstract |
The present invention provides a laminated porous film having excellent air permeability characteristics and mechanical strength, and capable of exhibiting breakdown characteristics superior to those of conventional polypropylene porous films. A laminated porous film in which at least a first layer and a second porous layer are laminated, wherein each of the first layer and the second layer includes a polypropylene-based resin, and the first layer includes the first layer and the second layer. It is a layer formed of a composition comprising a mixed resin obtained by mixing a polypropylene resin and a thermoplastic resin having a crystal melting peak temperature of 170 ° C. or higher, and the second layer has a mixing amount of the thermoplastic resin as described above. It is a layer that is smaller or less mixed than the first layer, and has β activity and / or β crystal generation ability. [Selection figure] None |
