  • SEPARATOR FOR ELECTROCHEMICAL DEVICE AND METHOD FOR MANUFACTURING THE SAME
    Publication number: 20230327286
    Abstract: A separator for an electrochemical device, where the separator includes a semi-crystalline and/or amorphous polymer, such as polyvinyl acetate and polyethylene-co-vinyl acetate, as a binder polymer of an inorganic coating layer. The surfaces of the inorganic particles are at least partially coated with a coupling agent. Therefore, it is possible to prevent the inorganic particles from being detached from the inorganic coating layer. In addition, phase separation is accelerated under a humidified condition in manufacturing the separator so that the surface of the separator may be provided with an adhesive portion in which a large amount of binder polymer is distributed. As a result, the separator may have improved binding force to an electrode.
