Abstract: This application provides a displacement detection method for anode composite strip. The anode composite strip includes an anode plate and a separator attached to a surface of the anode plate, where the anode plate includes positioning holes. The displacement detection method includes: step S1000: obtaining an image of a portion of the anode composite strip including the positioning holes; and step S2000: calculating a displacement characteristic quantity based on the image, where the displacement characteristic quantity includes any one or any combination of a width direction displacement, a strip movement direction displacement, and a displacement angle.
