Abstract: A battery cell, a battery, an electricity consuming device and a preparation method are provided. The battery cell includes an electrode assembly and an adapter. The electrode assembly includes at least two electrode bodies arranged side by side along a first direction and tabs extending from the electrode bodies. The tab includes an extension portion and a bent portion, the extension portion extends from the electrode body along a second direction, the bent portion is connected with an end of the extension portion away from the electrode body and extends along a first direction, an adapter is connected with the tabs, the current of the electrode body is conducted by the adapter to the outside, a bending arrangement of the tabs enhances their structural strength, avoiding the problem of degradation in internal electrical connection performance of the battery due to damage to the tabs by an external force.
