description The present invention provides a one-sided electrode for a secondary battery comprising a current collector, an electrode mixture layer applied to one surface of the current collector, and an electrode distortion-preventing layer formed on the other surface of the current collector to which no electrode mixture is applied. The one-sided electrode according to the present invention exhibits significantly reduced warping or curling after a rolling process and has the advantages of facilitating subsequent processes and enabling enhanced productivity.
