Provided are a method and device for correcting positions of tabs of an electrode assembly. The electrode assembly includes anode electrode plates and cathode electrode plates stacked alternately in a first direction. The method includes: determining whether there are a plurality of consecutive tabs misaligned with each other in a first electrode plate assembly; and adjusting, if there are a plurality of consecutive tabs misaligned with each other, a cutting position of the first electrode plate assembly to adjust a width of first electrode plates obtained after cutting, such that tabs of a plurality of first electrode plates obtained after cutting the first electrode plate assembly are aligned with each other, the first electrode plates being anode electrode plates or cathode electrode plates.

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.
