Abstract

The present application provides a battery cell, a battery, an electrical apparatus, and an energy storage cabinet, and belongs to the field of battery technologies. The battery cell includes a shell, a plurality of pole groups and a plurality of electrode terminals. The shell has a wall portion. A plurality of pole groups are accommodated in the shell and arranged along a first direction. The pole groups comprise a main body group and two tab groups. The two tab groups are spaced apart along the first direction on one side of the main body group in a second direction, and the two tab groups have opposite polarities. A plurality of electrode terminals are installed on the wall portion and are spaced apart along the first direction. Along the first direction, two tab groups close to each other in two adjacent pole groups have the same polarity and are electrically connected to one electrode terminal in common, and two tab groups farthest apart from each other in the plurality of pole groups are electrically connected to two electrode terminals respectively. This can save electrode terminals provided on the shell, and is beneficial for optimizing the production rhythm of the battery cells, thereby improving the production efficiency of the battery cells and reducing the manufacturing cost of the battery cells.
