Abstract
This application discloses a battery cell, a battery, and an electric apparatus. The battery cell includes a case, an electrode terminal, and a sealing member. The electrode terminal has an insertion portion and a flange portion connected in the axial direction, with the flange positioned outward of the insertion portion and extending beyond it in the radial direction. A groove extends along the axial direction of the terminal, with its opening on the outer face of the flange. The sealing member includes a body portion located in the groove to seal it, and an adapter portion at the end of the body portion facing away from the case. The adapter has a smaller radial dimension than the body and protrudes axially from the flange and body to allow electrical connection with an external component. This structure helps reduce heat transfer to the electrode terminal, thereby improving thermal stability and safety of the battery cell.
