PURPOSE:To enhance the resistance against leakage of liquid, by making a gasket serving as an opening seal, of synthetic resin mixed with glass beads. CONSTITUTION:An anode black mix 2 and a separator 3 consisting of a porous polypropylene film 4, cellophane 5 and a mixed sheet 6 of vinylon and rayon are provided in an anode can 1. The opening of said anode can 1 is sealed up with a cathode collector 8 filled with a cathode agent 7 and fitted with an interposed gasket 9. A button-type alkaline battery is thus manufacutred. The gasket 9 of the battery is made of synthetic resin mixed with glass beads. The synthetic resin is preferably polyamide, polyolefin or the like. The amount of the glass beads to be added is 20-40wt%. The mean grain size of the beads is preferably 3-60mum. |
