PURPOSE:To increase the capacity, the liquid-leakage resistance and the long- period preservation performance of a sealed organic-electrolyte battery by using an annular ceramic body as an insulating sealing member. CONSTITUTION:A current-collecting body 22 made of titanium is fused to the inner wall of a positive can 21, which has a brimmed part extending outward from its opening end and is made of a stainless steel or the like. A grid 27 is fused to the inner surface of a metallic terminal 26, and a part of a negative lithium sheet 31 is pressed and fixed upon the surface of the grid 27. The metallic terminal 26 is fused to the inner circumference surface of an annular ceramic body 28, and a metallic case 29 made of copal, 42-alloy or 426-alloy is fused to the outer circumference surface of the body 28. In addition, the outer peripheral part 29a of the case 29 and the opening end part 21a of the positive can 21 are welded and fused together by laser or the like. A cup-like insulating body 30 made of a plastic film such as a polypropylene film, is provided inside the body 28, the case 29 and the can 21. |
