Document Type and Number:

Japanese Patent JP7337089

Kind Code:

B2

Abstract:

The present disclosure relates to a separator for an electrochemical device, including a porous substrate and an inorganic coating layer formed on at least one surface of the porous substrate. The inorganic coating layer includes a binder resin and inorganic particles, and the binder resin includes a polyvinylidene fluoride-based resin and shows a low electrolyte solution absorption ratio. The separator has excellent adhesion with an electrode and shows low resistance characteristics.
