LAMINATED POROUS FILM AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
| 摘要 |
The present invention provides a laminated porous film and a non-aqueous electrolyte secondary battery. The laminated porous film is a laminated porous film in which a heat-resistant layer comprising a binder resin and a filler is laminated on one or both of the surfaces of a porous film substrate mainly comprising a polyolefin, wherein a part occupied by at least one out of the binder resin and the filler is formed in the porous film substrate so as to touch the heat-resistant layer, and the total thickness of the occupied part is not less than 1% and not more than 20% of the overall thickness of the porous film substrate. The non-aqueous electrolyte secondary battery comprises the laminated porous film according as a separator. |
