Abstract: This application provides a detection method for electrode plate, a detection apparatus for electrode plate, a stacking system, a detection device, and a computer-readable storage medium, where the electrode plate includes a coated portion and an uncoated portion located on at least one side of the coated portion in a longitudinal direction. The detection method includes: step S1000: obtaining dimensional parameters D1 . . . DN at different detection positions P1 . . . PN of the uncoated portion in a transverse direction perpendicular to the longitudinal direction; and step S2000: comparing the dimensional parameters D1 . . . DN with a dimensional detection standard S to determine whether the uncoated portion is folded, where N is a positive integer, and N is greater than or equal to 2.

Abstract: Embodiments of the present application provide an apparatus and a method for manufacturing an electrode assembly. The apparatus includes a driving portion, used for driving pole pieces to fall them from the driving portion; and a first support portion, arranged below the driving portion, and used for receiving the falling pole pieces, so that the pole pieces are stacked on the first support portion. The distance between an initial position of the upper surface of the first support portion and the driving portion being in a range of W to 2W. The initial position is the position of the upper surface of the first support portion when receiving the first pole piece of the electrode assembly, and W is the length of each pole piece. The apparatus can effectively stack the pole pieces to obtain an electrode assembly, and has high stacking efficiency.
