Title:
フィルムの製造方法、電池用セパレータフィルム、非水電解液二次電池用セパレータ及び非水電解液二次電池
Document Type and Number:
Japanese Patent JP6632501
Kind Code:
B2
Abstract:
The present invention easily implements desired drying ability by suppressing damage to a film. A manufacturing method of a film, when driving a manufacturing process including a drying process, performs setting of a drying condition in the drying process by dividing into at least two sections of a first section and a second section which is a section later than the first section. The drying condition is changed so that the corresponding drying condition becomes stronger with a time in at least a part of the first section, and the drying condition is nearly and constantly maintained in the second section.
