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.

Provided are a composite separator including a coating layer including inorganic particles and a binder formed on a porous substrate, which has improved coatability and improved thermal shrinkage, and a lithium secondary battery using the same.

Composite separator and electrochemical device including the same

The present invention relates to a binder for an anode for a secondary battery, an anode including the binder, and a secondary battery including the anode. More particularly, the present invention relates to a binder for an anode for a secondary battery that has excellent heat resistance and mechanical properties and an improved binding force because a copolymer is used for the binder, and an anode for a secondary battery. In addition, expansion and shrinkage of the anode may be efficiently suppressed, such that charge and discharge life characteristics and performance of the secondary battery may be improved.
