Abstract: The present application provides a battery including a shell, a top cover, a battery cell, and a second adapter part. The top cover seals an upper end of the shell and forms a cavity together with the shell, and the battery cell is located in the cavity. The shell includes a side wall surrounding the cavity and a bottom shell arranged at a lower end of the side wall. The battery cell has a first tab and a second tab, the bottom shell is electrically connected to the second tab, the second adapter part includes a second connection sheet and a second pin, the second adapter part is connected to the bottom shell through the second connection sheet; one end of the second pin is connected to the second connection sheet, and the other end thereof extends out of an outer edge of the bottom shell.

Abstract: Disclosed is a battery, the battery including a housing, where the housing is a metal piece, the housing includes a bottom shell and a cap, and the cap covers an opening of the bottom shell; the cap includes a mounting hole, a conductive sealing pin disposed in the mounting hole, a side periphery of the sealing pin is provided with a clamping groove, and the cap close to the mounting hole extends into the clamping groove and is in clamped connection to the clamping groove; and a seal is provided at a connection between the clamping groove and the cap, and the seal is an electrical insulator. The structure improves application stability of the battery and improves sealing performance and safety of the battery.
