Abstract
The present invention relates to an electrode manufacturing method, an electrode manufactured thereby, and a battery comprising the same, the electrode manufacturing method comprising the steps of: applying an electrode active material onto a collector; and radiating a laser such that the end of an electrode active material layer, which has been obtained by applying the electrode active material, becomes straight, thereby removing the electrode active material. The present invention is advantageous in that the difference in area between active materials applied to the positive and negative electrodes, respectively, is minimized, thereby increasing the capacity and improving the stability of the battery.
