摘要 |
An object of the invention is to provide a separator for a nonaqueous secondary battery, which has good adhesion to electrodes and is also capable of ensuring sufficient ion permeability even after attachment to an electrode. The separator for a nonaqueous secondary battery of the invention includes a porous substrate and an adhesive porous layer formed on at least one side of the porous substrate and containing a polyvinylidene-fluoride-based resin. The separator for a nonaqueous secondary battery is characterized in that the adhesive porous layer has a crystallinity of 20 to 35%.
