PURPOSE:To improve the adhesion to a negative electrode can and facilitate manufacture by placing a specified volume of lithium mass at the bottom of the negative electrode can, pressing and deforming it with a cylindrical pressing rod, and molding it into a lithium tube negative electrode. CONSTITUTION:A lithium negative electrode 4 is formed by placing a specified volume of lithium mass 3 at the bottom of a negative electrode can 2 made of stainless steel, pressing and deforming said lithum mass 3 with a cylindrical pressing rod 1 made of material to which lithium such as polystylene, etc. does not adhere. Then, a cylindrical lithium battery is formed by arranging therein, a positive electrode formed by inserting a separator 5 and a collection rod 7 in the central part of positive electrode black mix 6 and sealing thus obtained assembly. As a result, the outer circumferential surface of the lithium negative electrode 4 is made to adhere to the inner circumferential surface of the negative electrode can 2 and the property of collection can be improved and then battery performance can be improved. Also, the creation of the negative electrode 4 can be facilitated and the manufacturing cost can be reduced. |
