MULTILAYER ELECTRODE FOR A SECONDARY BATTERY, AND SECONDARY BATTERY INCLUDING THE ELECTRODE

An electrode for secondary battery comprising:an electrode current collector in which a plurality of through-holes are formed;a first electrode mixture layer including an electrode active material, a binder, a conductive material, and 0.5 to 2 % by weight of a thickener based on the total weight of the mixture, on at least one surface of the electrode current collector; anda second electrode mixture layer including an electrode active material, a binder, and a conductive material on the first electrode mixture layer, wherein the second slurry further comprises a thickener in a weight less than a weight of a thickener included in the first slurry. In manufacturing an electrode including an electrode current collector with a plurality of through-holes, processability may be secured by preventing leakage of a slurry, and thus, a uniform electrode mixture layer may be formed.
