The electrode assembly comprises a positive pole piece and a negative pole piece. The positive pole piece and the negative pole piece are stacked to form a straight flat region. The housing is used for accommodating the electrode assembly, wherein the housing comprises a first wall part and two second wall parts. The two second wall parts are respectively located on two sides of the straight flat region. The pressure relief part is arranged on the first wall part, and the pressure relief part is formed with a score groove. First weak sections and second weak sections are formed at the bottom of the score groove, and the thickness of the second weak sections is less than the thickness of the first weak sections.",
