Abstract

PURPOSE:To improve the leakage resistance by making the section of sealing packing U-shaped to pinch the end of cathode vessel and by selecting the ratio of heights of both sides of the U-shaped part in a specific range. CONSTITUTION:Anode agent 2 is contained in the anode vessel 1 which plays a role of anode terminal, cathode agent 7 contained in the cathode vessel 6 which plays a role of cathode terminal is placed on the impregnant 5 of electrolyte on the separator 3. The circumference edge of the cathode vessel is covered with packing 8, the end of packing is tightened with the anode vessel to form the button-shaped battery. The section of packing is U-shaped, the U-shaped part pinches the edge of cathode vessel. Also the ratio of height M in the cathode agent side to height L in the anode agent side is selected in the range such that M/L>=2/3.
