Abstract
Provided are a binder composition for a secondary battery, a negative electrode including the same, and a secondary battery including the same. More particularly, the binder composition for a secondary battery having a three-dimensional structure, which is prepared by mixing a copolymer having specific repeating units and a polymer-type additive containing nitrogen (N) bonded to two or three carbons (C) in the repeating unit, has excellent mechanical properties and may effectively improve a binding force. The negative electrode and the secondary battery including the binder composition for a secondary battery effectively suppress expansion of a negative electrode to manufacture a secondary battery having excellent charge/discharge cycle characteristics and battery performance.
