Zusammenfassung:	This application provides a shell component, a battery cell, a battery, and an electrical device, and relates to the technical field of batteries. The shell component includes a non-fragile region and a fragile region formed in one piece. A groove portion is disposed on the shell component. The non-fragile region is formed around the groove portion. The fragile region is formed at a bottom of the groove portion. The fragile region is configured to be broken when the battery cell is relieved of an internal pressure. A hardness of the fragile region is H1, and a hardness of the non-fragile region is H2, satisfying: H1>H2. The hardness of the fragile region is greater than the hardness of the non-fragile region.
