  • Publication number: 20230207967
    Abstract: A composite separator for an electrochemical device. The composite separator has an electrode adhesive layer, and two types of solvents are used when coating the electrode adhesive layer. The ratio of polarity of the solvents is used to induce a beta crystal phase of the second binder resin, and thus a uniform porous structure is formed to provide an improved lithium-ion conduction path. In this manner, even when the electrode adhesive layer is formed on the composite separator, the composite separator does not cause an increase in resistance.
