Document Type and Number:
Japanese Patent JP6772310
Kind Code:
B2
Abstract:
Provided is a separator (10). The separator (10) includes a substrate (11) and a coating layer (12) on at least a surface of the substrate (11), wherein the coating layer (12) includes first organic particles (13), second organic particles (14), and a first binder (15), the first organic particles (13) have a smaller mean particle diameter (D50) than that of the second organic particles (14), and at least one of the first organic particles (13) and the second organic particles (14) has a core-shell structure. When the separator (10) is used, adhesion of the separator (10) to an electrode (2, 3) may be enhanced, and thus battery safety may be enhanced.
