Abstract
The present invention provides an anode slurry for a secondary battery and an anode comprising the same, in which the dispersibility of an anode active material is improved by increasing the adsorption amount of CMC with respect to the anode active material by adjusting the degree of substitution or physical properties such as molecular weight, and a CMC blend amount is reduced so as to increase the slurry solid content and reduce the resistance of a battery.
