Abstract

The present application provides a battery cell, a battery, and an electric apparatus, and pertains to the field of battery technology. The battery cell includes a housing, a pressure relief mechanism, and a first shielding member. The housing has a wall portion, and along a thickness direction of the wall portion, the wall portion has a first surface facing away from an interior of the housing, the first surface is provided with a groove, and a groove bottom surface of the groove is provided with a pressure relief hole. The pressure relief mechanism is disposed in the pressure relief hole, and the pressure relief mechanism is configured to release an internal pressure of the battery cell. The first shielding member is connected to the first surface and covers the groove. With the first shielding member provided on the first surface, and the first shielding member covering the groove, the first shielding member can shield the groove, mitigating the entry of impurities or electrolyte into the groove. This helps reduce the accumulation of impurities or electrolyte in the groove, thereby reducing corrosion of the pressure relief mechanism caused by impurities or electrolyte accumulated in the groove entering the pressure relief hole, and facilitating the improvement of the use reliability and service life of the battery cell.
