ELECTRODE SHEET, BATTERY CELL, BATTERY, ELECTRIC DEVICE, AND PREPARATION METHOD FOR ELECTRODE SHEET

Provided in the embodiments of the present application are an electrode sheet, a battery cell, a battery, an electric device, and a preparation method for the electrode sheet, which can effectively ameliorate the problem of powder shedding during a cutting process of an electrode sheet to be cut, thereby reducing the risk of an internal short circuit occurring in a battery cell caused by overlapping between a positive electrode sheet and a negative electrode sheet, and thus improving the yield of the battery cell. The electrode sheet comprises: a first current collector, which comprises a first body and a tab region connected to an edge of the first body, the first body comprising a coated region and an edge region; and a first electrically conductive layer disposed on a surface of the coated region, wherein the thickness of the electrode sheet in the edge region is less than that of the electrode sheet in the coated region.
