PURPOSE:To improve resistance to leakage and preservation capacity by separating cathode black mix and an electrolyte, housing them in a cathode can, loading anode black mix through a separator, and shrink-fitting the cathode and anode cans through an insulating coat. CONSTITUTION:The surface of the riser 7b of a cathode can 7 is coated with an insulating coat 7d such as a fluorine series coat. At the same time a step 7c is formed at the center of the inner wall and cathode black mix 9 that is making- tablet-molded internally and an electrolyte 10 injected in the external space are housed in it. In addition, while a separator 12 is being loaded on the step 7c and then on the cathode black mix 9, air is pressed with a jig and is exhausted. Then anode black mix 11 that is making-tablet-molded is loaded and an anode can 8 is heated. Subsequently the cylindrical section 8b is shrink-fit to the riser 7b of the cathode can through the insulating coat 7d and is sealed. As a result, the intervention of internal air is removed and adhesion is improved. At the same time preservation capacity can be stabilized by removing internal shortcircuit. |
