  • Patent number: 10862126
    Abstract: The present invention relates to a binder composition for a secondary battery, including: a copolymer having a functional group; and an alkali metal ion bound to the functional group of the copolymer or with which a constituent element of the functional group is substituted. The binder composition exhibits enhanced adhesive strength and also exhibits low resistance due to the alkali metal ion included in the copolymer, and thus may exhibit more stable electrochemical performance.
