ELECTRODE QUALITY EVALUATION METHOD AND ELECTRODE MANUFACTURING METHOD

Provided is a method of evaluating electrode quality, which includes: providing a plurality of electrodes which include a current collector and an active material layer formed on the current collector and have not been roll-pressed; measuring a color coordinate value of the active material layer of each of the plurality of electrodes using an optical instrument and calculating an average value; and evaluating the electrodes as good products when a difference between the color coordinate value measured from the individual electrodes and the average value is no more than a predetermined value and as defective when the difference exceeds the predetermined value.
