SEPARATOR PRODUCTION METHOD AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
| 摘要 |
A production method according to the present invention is a method comprising impregnating a laminated porous film, which is formed by laminating a heat-resistant layer containing polyvinyl alcohol (PVA) and an inorganic filler on one side or both sides of a substrate material porous film predominantly composed of polyolefin, with a solution containing a compound having the ability of cross-linking PVA, and then removing a solvent. The present invention can produce a separator having excellent heat shape retainability even when PVA is used for a binder resin for forming a heat-resistant layer. |
