In order to uniformly charge and discharge characteristics of a secondary battery, the positive electrode active material slurry and the negative electrode active material slurry should be uniformly coated on a current collector with a constant thickness. That is, there may be a difference in electron density depending on the distribution amount of the positive electrode active material or the negative electrode active material on the current collector, which is related to the performance of the secondary battery. Therefore, it is necessary to accurately manage the thickness of the positive electrode active material or the negative electrode active material when manufacturing the positive electrode and the negative electrode. Therefore, in order to accurately measure the thickness of the electrode active material, the electrode active material coated on one side of the current collector is removed to prepare an electrode cross-section sample, and then the electrode active material coated on the opposite side of the current collector is used with a thickness measuring device using a confocal displacement sensor.

It may be configured to contact the electrode active material of the facing portion 3. In addition, a pressure sensor is employed in the height adjusting unit 133 so that when the height adjusting unit 133 is withdrawn and the cutting blades 131a and 131b and the crushing blade 132 press the electrode facing portion 3, a certain pressure is applied. When the above pressure is sensed, the withdrawal of the height adjusting unit 133 is stopped so that the electrode foil 2 and the electrode measuring unit 4 are not damaged.

It is not easy to remove 100% of the electrode active material from the electrode foil 2 with only one electrode removal operation by the cutting blades 131a and 131b and the crushing blade 132 . Accordingly, after checking the remaining electrode active material by measuring the thickness of the electrode facing portion 3, an additional removal operation is performed if necessary.

For example, in order to measure the thickness of the remaining electrode active material, as shown in FIG. 11 , the body block 110 is rotated so that the electrode thickness meter 140 is positioned in a downward direction facing the electrode facing portion 3 . Here, the electrode thickness meter 140 may be, for example, an infrared film thickness meter that measures the film thickness by analyzing the reflected wavelength of infrared rays, or a non-contact film thickness meter such as a microwave method or a laser method.
