  • Publication number: 20240170678
    Abstract: Disclosed are an anode including a core part and a binder and a secondary battery including the same. Particularly, a coating layer including a polymer is provided between the core part and the binder and thus blocks electron transport paths from the core part to the binder. Thereby, decomposition of the binder is suppressed, and thus, the charge capacity and the initial Coulombic efficiency of the secondary battery are increased.
