Abstract
The present invention relates to an apparatus for evaluating drying quality of an electrode, and the apparatus includes: an oven configured to provide a space in which an electrode is dried; a measuring unit configured to be positioned at an outlet of the oven and measure a color coordinate value of an electrode active material layer with respect to the dried electrode; and an determination unit configured to determine whether the electrode is dry from the color coordinate value, wherein the determination unit sets a reference value, and determines that a dry state of the electrode is defective if the measured color coordinate value is less than the reference value, and a difference between the measured color coordinate value and the reference value is more than a preset value.
