Beschreibung
Zusammenfassung:	A negative electrode for a rechargeable lithium battery and a rechargeable lithium battery including the same are provided. The negative electrode includes a SiC composite negative electrode active material and a binder, wherein the binder includes a first binder that is an acrylic copolymer. The acrylic copolymer includes a first acrylic acid monomer, a second acrylonitrile monomer, and a third (meth)acrylate monomer, the first acrylic acid monomer includes acrylic acid substituted with a lithium ion, and the third (meth)acrylate monomer is a (meth)acrylate monomer including an ethylene glycol group and has a weight average molecular weight (Mw) of less than about 900 g/mol.
