Abstract
Disclosed are a method of manufacturing an electrode for secondary batteries that includes surface-treating a current collector so as to have a morphology wherein a surface roughness Rof 0.001 μm to 10 μm is formed over the entire surface thereof to enhance adhesion between an electrode active material and the current collector and an electrode for secondary batteries that is manufactured using the method.
