Beschreibung
Zusammenfassung:	A negative electrode slurry includes a negative electrode active material including a first active material including silicon atoms in an amount of greater than or equal to about 20 wt % and less than or equal to about 100 wt % of the first active material, a binder, and a solvent to disperse the negative electrode active material and the binder in the negative electrode slurry, wherein the binder includes a particulate dispersed body and a water-soluble copolymer including a copolymer including an acrylic acid-based monomer unit, a sodium styrene sulfonate monomer unit, and an acrylonitrile-based monomer unit, a weight average molecular weight of the copolymer is about 300,000 to about 2,000,000, and an amount of the water-soluble copolymer is greater than or equal to about 0.5 wt % and less than or equal to about 2 wt % based of 100 wt % of the negative electrode active material and the binder.
