PURPOSE:To make it possible to supply two different voltage to the external circuit and to increase volume efficiency and weight efficiency by accommodating two electrodes which have the same polarity but different electrode potential and are electrically insulated each other and one electrode having the porality opposed to the two electrodes and serving as their counter electrode in a container. CONSTITUTION:A disk-like manganese dioxide positive electrode 3 having a hole in the center is placed on the inside of sealing plate 3. A stainless steel pin 5 of a hermetically sealed terminal 2 is covered with a polypropylene tube 6, passed through the central holes of the positive electrode 3 and a separator 4, and welded to a current collecting net 8 which is pressed against the upper surface of a negative electrode 7 comprising zinc. A disk-like polypropylene nonwoven fabric separator 4' is in contact with the lower surface of the negative electrode 7, and surrounds the negative electrode 7 together with the separator 4. A mercuric oxide positive electrode 9 is placed on the lower side of the separator 4' and is in contact with the inner bottom of a stainless steel case 10. |
