The present invention relates to an electrode active material slurry, which includes (a) an electrode active material, (b) a conductive agent, (c) a binder, (d) a solvent, and (e) a cellulose-based compound having a weight-average molecular weight (Mw) of 2,000,000 to 3,000,000, a degree of substitution of 1.0 to 1.2, and a viscosity (Brookfield viscometer, speed of 12 rpm) of 4,000 cps to 10,000 cps, and an electrode and a lithium secondary battery which include the same. Phase stability of the electrode active material slurry may be improved and battery characteristics may be improved by using the cellulose-based compound having molecular weight and degree of substitution within a specific range.

Electrode active material slurry and lithium secondary battery including the same

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.

Anode slurry for secondary battery for improving dispersibility and reducing resistance, and anode comprising same

The present invention relates to a negative electrode including an active material layer which includes carbon-based particles having an oxygen content of 700 mg/kg to 1,700 mg/kg, and a secondary battery including the same.
