Abstract: A lithium ion battery including a lithium ion battery core, a cylindrical aluminum shell, a positive guide needle of the anode, a negative guide needle of the cathode, a rubber seal having a circular recess in the outside of the side wall, and a sealing band. The battery core is arranged within the shell. The positive and negative guide needles are led out from under the seal. The battery core together with the rubber seal is sealed in the shell via the sealing band which is molded from an insulated moldable material by rolling. The sealing band is applied only to the top portion of the shell, the side wall of the seal, and the edge of the top wall of the seal. The bottom wall of the shell is provided with a pressure relief valve.

Abstract: A lithium ion battery including a lithium ion battery core, a cylindrical aluminum shell, a positive guide needle of the anode, a negative guide needle of the cathode, an end cover, a sealing band, and a girdling band. The lithium ion battery core is arranged within the cylindrical aluminum shell. The positive guide needle of the anode and the negative guide needle of the cathode are led out from the end cover. The lithium ion battery core is sealed in the cylindrical aluminum shell via the sealing band and the girdling band which are molded by rolling. The bottom plane of the cylindrical aluminum shell is provided with an explosion-proof impression. The lithium ion battery has high capacity, high power, and high voltage. The batters also has a simple structure, is convenient to use, and features high safety.
