Abstract: A method for detecting a qualified rate of a battery electrode sheet includes collecting a first weight corresponding to a to-be-detected electrode sheet, drying the to-be-detected electrode sheet in a drying apparatus for a preset duration and collecting a second weight corresponding to the dried to-be-detected electrode sheet, and determining a detection result of the to-be-detected electrode sheet based on a ratio of a drying difference to the second weight. The drying difference is a difference between the first weight and the second weight.
