  • Publication number: 20240128617
    Abstract: A power storage cell includes an electrode assembly, a cell case, and an external terminal. The cell case has a case main body and a lid. The lid has a lid main body connected to an opening of the case main body and charged positively or negatively in the electrode assembly, and a short-circuit member connected to the lid main body, the short-circuit member being able to short-circuit the lid main body and the external terminal. The external terminal includes a terminal plate. The short-circuit member includes an elastic portion made of a conductive resin. The elastic portion is separated from the terminal plate when an internal pressure of the cell case is less than a predetermined pressure, and is elastically deformed to come into contact with the terminal plate when the internal pressure of the cell case is equal to or more than the predetermined pressure.
