Abstract

PURPOSE:To make better the adhesion between lithium and negative polar cover by placing a specific amount of lithium lump with respect to the final area of projected area on the inside surface of the negative pole cover and then by pressing them to cause a plastic deformation to take place. CONSTITUTION:The positive polar active substance 2 is housed in the positive polar current collector 1 serving as a positive pole terminal, its upper part is provided with the lithium 4 as negative pole closely adhered to the negative pole cover 5 through the separator 3, and the current collector 1 and the cover 5 are sealed through a packing to form a flat type lithium cell. The sound adhesion between the lithium 4 and the negative pole cover 5 of the cell is obtained by the procedure in which the lithium lump 13 is placed on the central part of the negativae pole cover 12 supported by the receiving mold 11 and then the lithium lump 13 is pressed from above by the pressing mold 14 to cause a plastic deformation to take place. The lithium lump 13 used is of such a size that its projected area is less than 30% of the final area b after adhesion.
