Abstract: The disclosure discloses a marking method and apparatus of a continuous composite strip. The method incudes: collecting a first sequence of images of the continuous composite strip; splicing multiple images of the first sequence of images according to a collection sequence, to obtain a to-be-detected image with at least one electrode sheet structure; and marking, in case where two electrode sheet edges are identified in the to-be-detected image, a position of the collection-sequentially second electrode sheet edge in the continuous composite strip as an electrode sheet division position of the continuous composite strip. The method determines the electrode sheet division position by identifying the electrode sheet edges in the continuous composite strip, obtains the specific position information of the electrode sheet, and accurately performs the sheet division marking of the continuous composite strip.
