請求の範囲第１項記載の円筒形リチウム電池。[Scope of Claim for Utility Model Registration] (1) A long positive electrode plate equipped with a positive electrode current collector rod that also serves as a wound core body and a negative electrode plate having a thin metal plate connected to one end of the long metal lithium as a separator. In a cylindrical lithium battery, the spiral electrode group is entirely covered with the metal thin plate, and further, the winding end of the positive electrode plate is formed between the metal thin plate and the metal lithium. The connecting portion is located on the outer periphery within the first half of the winding side, and the outer peripheral surface of the connecting portion faces the thin metal plate with a separator in between, and the terminal end of the thin metal plate extends beyond the connecting portion to the thin metal plate itself. A cylindrical lithium battery characterized by being in contact with. (2) Practical use characterized in that the metal thin plate and the metal lithium are configured such that at the connecting portion between the two, the metal thin plate is located on the inside of the winding, and the metal lithium is located on the outside of the winding. A cylindrical lithium battery according to claim 1 of patent registration.
