Abstract

The present disclosure provides a battery cell (20), a battery (100), an electrical apparatus, and an energy storage cabinet, which belongs to the technical field of batteries. The battery cell (20) comprises a shell (21), a first electrode terminal (22), a first current collecting member (23) and a plurality of electrode assemblies (24). The shell (21) has a wall portion (211). The first electrode terminal (22) is mounted on the wall portion (211). The plurality of electrode assemblies (24) are accommodated inside the shell (21), and the plurality of electrode assemblies (24) are stacked along a first direction. The electrode assembly (24) comprises a main body portion (241) and a first tab (242). Along a second direction, the first tab (242) is provided at an end of the main body portion (241), and the first tabs (242) of the plurality of electrode assemblies (24) are located at the same end of the main body portion (241). The second direction intersects with the first direction. The first current collecting member (23) electrically connects the first electrode terminal (22) and each of the first tabs (242). Therefore, there is no need to provide a plurality of first current collecting members (23) inside the shell (21) to connect with the first tabs (242) of the plurality of electrode assemblies (24), and there is no need to increase the thickness or volume of a single electrode assembly (24), which can effectively reduce the manufacturing difficulty of the electrode assembly (24) and reduce the manufacturing difficulty of the large-capacity battery cell (20).
