Device for Testing Dryness of Electrode, and Method for Testing Dryness of Electrode

Abstract

A device for testing the dryness of an electrode may include an electrode substrate in which an electrode slurry is applied onto a collector, a standard sample, a light emitting unit that includes a light source and a bifurcated optical fiber connected to the light source. The light emitting unit may selectively irradiate light to any one of the electrode substrate or the standard sample through a first optical fiber of the bifurcated optical fiber. The device may also include a light receiving unit with a spectrometer that may selectively receive light reflected from any one of the electrode substrate or the standard sample. The light receiving unit may and analyze the reflected light. The device may also include a control unit that may correct at least one of the light source or the spectrometer based on the analyzed reflected light of the spectrometer.
