Abstract: Disclosed are a case, a battery cell, a battery, and an electrical apparatus. The case includes a case body and a pressure relief structure, the case body accommodates an electrode assembly, and the pressure relief structure included a plurality of first pressure relief grooves disposed at intervals on the case body along the circumferential direction of the case body. The case body ruptures along the first pressure relief grooves when the pressure or temperature inside the case body reaches a threshold to release the pressure inside the case body. During a pressure relief process, even if one of the first pressure relief grooves is shielded, the case body can still rupture along other first pressure relief grooves, so as to ensure the normal pressure relief of the case body, reduce the risk of fire and explosion of the battery cell, and improve the safety of the battery cell.
