METHOD OF PREPARING ELECTRODE FOR SECONDARY BATTERY, AND SECONDARY BATTERY INCLUDING THE ELECTRODE

A method of manufacturing an electrode for a secondary battery includes preparing an electrode current collector in which a plurality of through-holes are formed; applying a first slurry including an electrode active material, a binder, and a conductive material to at least one surface of the electrode current collector; and applying a second slurry including an electrode active material, a binder, and a conductive material on 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.
