Abstract

The present application provides a battery cell, a battery, and an electrical apparatus, which belongs to the field of battery technologies. The battery cell includes a case assembly, an end cover, and an electrode assembly. The case assembly is provided with an accommodating cavity having an opening formed therein. The case assembly has a first electrode lead-out portion and a second electrode lead-out portion. In a first direction, the first electrode lead-out portion and the second electrode lead-out portion are both located at one end of the case assembly away from the opening. The end cover covers the opening. The electrode assembly is accommodated in the accommodating cavity, and the electrode assembly includes a main body part, a first tab, and a second tab. The first tab and the second tab have opposite polarities. The first tab and the second tab are both arranged at one end of the main body part away from the end cover in the first direction. The first tab and the second tab are electrically connected to the first electrode lead-out portion and the second electrode lead-out portion, respectively. The end cover is provided with a pressure relief portion, and the pressure relief portion is configured to be capable of relieving an internal pressure of the battery cell. Therefore, it is conducive to reducing the difficulty of arranging the pressure relief portion on the battery cell.
