Abstract

PURPOSE:To enhance the discharge characteristic and the liquid leakage resistance of a sealed battery by sealing under reduce pressure the battery subjected to sealed assembly process. CONSTITUTION:A pressed and molded positive active material 2 is fitted in a battery case 1, and a separator 3 is placed on the material 2. A negative active material 7 made of zinc is placed in a lid 8 to which a gasket 5 is fitted. After that, the case 1 and the lid 8 are caulked to seal the battery, thereby constituting a sealed battery. The above sealing is carried out under reduced pressure so that air pockets 4 contaminating the positive active material 2, the separator 3 and electrolyte are expelled outside the battery.
