PURPOSE:To lengthen the storage life of a lithium battery by accommodating a cell sealed with an insulating gasket in an outer container sealed with an insulating gasket, and filling a resin in a space between the cell and the outer container. CONSTITUTION:A cell element containing a negative electrode 11 made of lithium or lithium alloy is arranged between a cell case 14 and a sealing plate 15 and sealed with an insulating gasket 16 to form a cell 1. The cell 1 is accommodated in an outer container 2 comprising an outer case 21 which also serves as a positive terminal and an outer sealing plate 22 which also serves as a negative terminal and sealed with an insulating gasket 23. A polyester group urethane resin 3 is filled in a space between the cell 1 and the outer container 2 to form a lithium battery. The penetration of the moisture in the atmosphere and leakage of the electrolyte can be prevented over a lengthy period of time to enhance the storage life of the battery. |
