description The present application relates to an electrode sheet, a battery cell and a battery. The electrode sheet includes a current collector and a protective layer. The current collector includes a coated region provided with an active material layer and an uncoated region without being provided with the active material layer. The protective layer is provided on at least a part of a surface of the uncoated region, and has a porosity of 0% to 95%. For the electrode sheet according to the present application, by providing the current collector with the protective layer, the contact resistance may be increased when the electrode sheet is short-circuited, and the discharge power and the thermal runaway probability of the battery cell may be reduced when the battery cell is internally short-circuited, thereby improving the safety performance of the battery cell.
