Abstract
A carboxymethyl cellulose is provided with a polydispersity index of 10 or more and a weight average molecular weight of 2,000,000 or more in a negative electrode mix slurry. Accordingly, phase stability of the negative electrode mix slurry is improved, achieving improved adhesiveness and low resistance of a negative electrode manufactured therefrom.
