The embodiments of the present application relate to an electrode sheet and a battery cell including the same. The electrode sheet according to an embodiment comprises an electrode sheet body and a plurality of tabs connected to the electrode sheet body. The width of each of the plurality of tabs is different from one another; or the length of each of the plurality of tabs is different from one another. The electrode sheet and the battery cell provided in the embodiments of the present application ensure that each of the tabs in the electrode sheet can electrically conduct well with the tab lead. Thus, the battery cell provided in the present application has the advantage of good electrical conductivity.
