Abstract

PURPOSE: To obtain sealant with excellent liquid-proofness by setting up a chromic layer on the surface of a metal sealing plate, coating accelerator to chelate-couple both the surface of this layer and thermo-plastic high polymer resin, thermowelding the above resin, and forming the sealant.
CONSTITUTION: The positive electrode active material 2 which is pressureized along with the annular ring 3 and molded in a body is set up at the metal battery case 1 and the negative electrode active material 5 of amalgamated zinc powder is arranged through the separator 4. Batteries are formed by sealing the nail-shaped conductive material 7 which makes contact with this negative electrode active material 5 and functions as a collection body with the sealing plate 6 united in a body by welding. The chromic layer 8 is formed on the surface of this sealing plate 6 except for its terminal and collection surface and the chelate accelerator 9 is coated on the surface of this layer 8. Then, the thermo-plastic high polymer resin 10 with acid amide coupling, for example, polyamide 6 is thermowelded and the plastic 11 is molded in a body by the insert molding process into the sealing plate 6. As the above accelerator 9, an organic or inorganic compound which is chelate-coupled to the chromic ion of the chromic layer 8, for example, citric acid is used.
