CONSTITUTION:A positive mix 1 molded in a tablet form and a positive ring 2 are pressed in a positive can 3 to form a positive part. A separator 4 and an absorbent mat 5 are placed on the positive part, and a negative can 7 combined together with a gasket 6 coated with a sealant and filled with a negative active material 8 is placed on the absorbent mat 5. The edge of the positive can 3 is crimped with the negative can 7 pressed at a pressure of 1-5kg/cm to seal a battery. The sealant arranged between the gasket 6 and the negative can 7 is filled between the upper and lower parts of the reversed curl part of the negative can. Therefore, seal effect is improved and leakage resistant performance is increased.,下面是Manufacture of button type alkaline battery专利的具体信息内容。
