The utility model discloses a
lithium battery cover plate and a
lithium battery. The
lithium battery cover plate is connected with a transmission circuit board and a connecting line, and comprises a main body, a battery positive pole and a battery negative pole which are arranged at two ends of the main body, and a
safety valve arranged between the battery positive pole and the battery negative pole, the
lithium battery cover plate further comprises a connector which is arranged on the top surface of the main body; the connector sequentially comprises a base, an isolation ring, a sealing ring and a sealing
gasket from top to bottom. The transmission circuit board is arranged between the sealing
gasket and the sealing ring; the connecting wire is arranged on the outer side of the sealing ring; the isolation ring, the sealing ring, the transmission circuit board and the sealing
gasket are pressed and fixed on the main body through the base, and the sealing ring is tightly attached to the transmission circuit board through deformation. The
lithium battery comprises a shell and the
lithium battery cover plate. Through the arrangement, the lithium battery cover plate has a better sealing effect on the connecting wire, and the sealing process is simpler. The lithium battery using the lithium battery cover plate is more convenient to assemble.
