COMPOSITION OF DISPERSANT USED IN PREPARATION OF ELECTRODE ACTIVE MATERIAL SLURRY, WHICH CONTAINS POLYMER MAIN CHAIN WITH SURFACE ADSORPTION AND SIDE CHAIN WITH NON-IONIC SURFACTANT PROPERTY AND USE THEREOF

摘要

PURPOSE: Provided are an anode active material slurry which has improved dispersibility and viscosity stabilization, and a lithium secondary battery with increased battery capacity. CONSTITUTION: The anode active material slurry for lithium secondary battery comprises (a) a carbon-based anode active material able to intercalate and de-intercalate lithium ions; (b) a conductive material; (c) a binder containing styrene-butadiene based polymer resin; (d) a thickener containing cellulose- or acrylate-based resin; (e) a dispersant containing polymer main chain with surface adsorption and side chain with non-ionic surfactant property; and (f) water. The dispersant is employed in an amount of 0.01 to 10 wt% based on the total weight of the anode active material slurry.
