A diaphragm detection method includes acquiring a target image of an electrode plate to be detected. The electrode plate to be detected includes an anode electrode plate and diaphragms respectively stacked on two sides of the anode electrode plate. The method further includes performing image processing on the target image to determine a target image region in the target image, and performing diaphragm misalignment detection on the electrode plate to be detected based on the target image region.

Diaphragm detection method, device and apparatus

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.

Method and device for correcting positions of tabs of electrode assembly

The present application discloses a method and device for controlling misalignment of electrode plates, electrode plates, an electrochemical cell, and a battery. The method includes: acquiring cut hole position information of an anode electrode plate, and calculating a first width deviation value corresponding to the anode electrode plate according to the cut hole position information and a calibration width of the anode electrode plate; acquiring tab position information of a cathode electrode plate, and calculating a second width deviation value corresponding to the cathode electrode plate according to the tab position information and a calibration width of the cathode electrode plate; and when the anode electrode plate and the cathode electrode plate are stacked, adjusting a feed position of the cathode electrode plate according to the first width deviation value, and compensating for a cut width of the cathode electrode plate according to the second width deviation value.
