Abstract: The present application provides an adapting sheet, a battery cell, a battery, and an electric apparatus. The adapting sheet includes a pole connection portion, a tab connection portion, and a bending portion. In a first direction, two sides of the pole connection portion are respectively connected to the tab connection portion through the bending portion. In a second direction, a height difference is formed between the pole connection portion and the tab connection portion, and the first direction is non-parallel to the second direction. The adapting sheet in the present disclosure is applied in the battery cell, so that the tab may be disposed at both sides of the pole in a width direction of the cell.
