Abstract

According to an embodiment of the present disclosure, provided is a device for inspecting the dryness of an electrode, comprising: a transport unit that transports the electrode to an electrode drying zone, an irradiation unit including a collimating lens which is fixed in a state of being tilted by 10 to 20 degrees with respect to the direction perpendicular to the transport direction of the electrode at an upper part separated from the electrode, and an optical fiber that irradiates a light source through the collimating lens, a measurement unit including a spectrometer and a light source respectively connected to the irradiation unit, and a spectrometer hub connected to the spectrometer, and a control unit including a display device connected to the spectrometer hub, a method for inspecting the electrode dryness that predicts electrode dryness from the measured reflectance through the device for inspecting the dryness of an electrode, a method for manufacturing an electrode for a secondary battery to which the electrode dryness inspecting method is applied, and a method for manufacturing a secondary battery including the same.
