Claims preview

1 . An anode mixture for a secondary battery, comprising an anode active material and a binder composition, wherein the binder composition is a one component binder comprising: hydrophobically modified alkali soluble emulsion (HASE); and a copolymer comprising a first repeating unit derived from an acrylamide (AAM)-based first monomer, a second repeating unit derived from an acrylic acid (AA)-based second monomer, and a third repeating unit derived from an acrylic nitrile (AN)-based third monomer, and the hydrophobically modified alkali soluble emulsion (HASE) and the copolymer are included in a weight ratio of 1:1.5 to 1:5, and the first repeating unit is included in an amount of 35 to 90 wt %, the second repeating unit is included in an amount of 0.1 to 30 wt %, and the third repeating unit is included in an amount of 5 to 40 wt % based on a total amount (100 wt %) of the copolymer, and wherein the binder composition is included in an amount of 3 to 10 wt % based on a total solid content (100 wt %) in the anode mixture. 2 . The anode mixture for a secondary battery of claim 1 , wherein the hydrophobically modified alkali soluble emulsion (HASE) comprises an acrylic polymer containing a hydrophobic functional group and an acid functional group. 3 . The anode mixture for a secondary battery of claim 2 , wherein the acrylic polymer containing the hydrophobic functional group and the acid functional group comprises a repeating unit represented by Chemical Formula 1 and a repeating unit represented by Chemical Formula 2: in the Chemical Formula 1, n is an integer of 1 to 10.
