A Method of Preparing an Electrode for Improving Capacity of Battery and the Electrode Manufactured by The Same

摘要

The present invention relates to a method of manufacturing a capacitor, comprising: applying an electrode active material on a current collector; And removing the electrode active material by irradiating a laser so that the end of the electrode active material layer coated with the electrode active material is in a straight line. The present invention also relates to an electrode and a battery including the electrode. The present invention has an advantage of minimizing the area difference between the anode and the anode active material, thereby increasing the capacity and improving the stability of the battery.
