The housing includes an accommodation cavity accommodating the electrode assembly. The positive electrode column and the negative electrode column are electrically connected to the electrode assembly, the positive electrode column and the negative electrode column respectively protrude from an outer end surface of the housing, the outer end surface is concave toward the accommodation cavity to form a concave part, and the concave part is disposed between the positive electrode column and the negative electrode column. A protecting member disposed at the concave part, the protecting member is electrically connected to the positive electrode column, and the protecting member is used for electrical connection with an external device or an external circuit. The concave part in the housing is formed concavely toward the accommodation cavity of the housing.",
