Claim 13:
14. The cylindrical lithium battery according to claim 12, further comprising an upper insulating sheet and a lower insulating sheet, the upper insulating sheet disposed between the positive electrode and the end of the wound body, the lower insulating sheet disposed between the negative electrode and the one other end of the wound body; wherein, the upper insulating sheet is a circular sheet structure, and has a partial fan-shaped hole, allowing the one other end of the first cathode tab and the one other end of the second cathode tab to pass through the partial fan-shape hole so as to be connected to the positive electrode; the lower insulating sheet is a sheet structure shaped as a partial circle, a radius of the partial circle is smaller than a radius of the one other end of the wound body, allowing the second anode tab and the third anode tab to be electrically connected to the negative electrode along an edge of the lower insulating sheet, and a center of the sheet structure shaped as a partial circle has a hole, allowing the first anode tab to pass through the hole so as to be connected to the negative electrode.
