Abstract:
A negative electrode slurry composition includes a negative active material, a binder, and a dispersant. The dispersant includes a polyacrylic acid (PAA) having a weight average molecular weight (Mw) greater than 10 and less than 10,000. A negative electrode and a lithium battery include the negative electrode slurry composition.
