Abstract
A battery cell, a battery, and an electrical device are provided. The battery cell comprises: a case with an opening; an electrode assembly accommodated within the case; and an end cover closing the opening, wherein the end cover is in sealed connection with the case through a first connection area and a second connection area, the strength of the first connection area is less than the strength of the second connection area, and the first connection area is configured to be actuated to release an internal pressure of the battery cell when the internal pressure exceeds a threshold. The battery cell, battery, and electrical device provided in the present application are capable of reducing the manufacturing cost of battery cells while ensuring the safety of batteries, and further reducing the assembly processes of the battery cells.
