1. A method for analyzing an electrode layer for a battery storage device in an electrode layer production facility, the method comprising:
acquiring an image comprising two pixels of the electrode layer using a hyperspectral camera, wherein a first pixel represents a first location of the electrode layer and a second pixel represents a second location of the electrode layer, wherein the first location and the second location are disposed adjacent to each other;
determining a first value for a material property of the electrode layer at the first location based on the first pixel;
determining a second value for the material property of the electrode layer at the second location based on the second pixel;
comparing the first value and the second value and determining a comparison value; and
determining characteristic properties of the electrode layer based on the comparison value.
