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 producing method of an electrode, an electrode produced thereby, and a battery comprising the same. The producing method of an electrode comprises the steps of: applying an electrode active material on a current collector; and removing the electrode active material by radiating laser in order that an end of the electrode active material on which the electrode active material is applied has a straight line. The present invention has effects of increasing capacity and battery stability by minimizing area difference of active materials applied on a negative electrode and a positive electrode.
