Electrode dryness inspection device, electrode dryness inspection method, and method for manufacturing electrodes and secondary batteries

Abstract

According to one embodiment of the present invention, A transfer unit that transfers electrodes to the electrode drying zone, An illumination unit including a collimator lens and an optical fiber that irradiates a light source through the collimator lens, fixed at an upper part separated from the electrode and tilted at an angle of 10 to 20 degrees with respect to a direction perpendicular to the direction of electrode movement; a measurement unit including a spectrometer and a light source connected to the illumination unit, and a spectrometer hub connected to the spectrometer; An electrode dryness inspection device including a control unit including a display device connected to a spectrometer hub, This provides an electrode drying inspection method that predicts electrode drying from the measured reflectance, A method for manufacturing electrodes for secondary batteries to which an electrode drying inspection method is applied, A method for manufacturing a secondary battery including this is provided.
