Abstract

PURPOSE:To improve the electrolyte leakage resistance by moistening a gasket before joining a negative can and the gasket in one body to prevent the separation of the negative can after joining in manufacturing a button type battery assembling the negative can and the gasket after joining them in one body. CONSTITUTION:A negative can 3 joined with a gasket 7 in one body with a liquid sealant 8 interposed is filled with a positive material 4 to form a negative unit. A positive black mix 2 is placed in a positive can 1 and molded to form a positive unit. The negative unit is inserted in the positive unit placed a separator 5 and an absorbent material 6 impregnated an electrolyte thereon. The open edge of the positive can is bent inward to seal a battery. In a button type battery manufactured by ordinary process, the contact between the bottom 7a of the gasket and the bottom 3a of the negative can is not good and cannot prevent the electrolyte leakage. To improve this defect, the fit tolerance of the gasket and negative can in joining them is decreased.
