SEPARATOR FOR ELECTRICAL STORAGE DEVICE AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a separator for an electrical storage device, which is obtained by laminating two or more fiber layers and characterized in that at least one of the fiber layers is a synthetic fiber layer that contains a synthetic fiber and a synthetic resin-based binder. Also disclosed is a method for producing the separator for an electrical storage device. Additionally disclosed are: a separator for an electrical storage device, which contains a thermoplastic synthetic fiber A, a heat-resistant synthetic fiber B, a natural fiber C and a synthetic resin-based binder; and a method for producing the separator for an electrical storage device.
