PURPOSE:To produce button type cells for various uses at a low cost by inserting a plurality of negative electrode tubes into a thermoshrinking tube, uniting them together in one body under heat, then cutting the tube to make up negative electrode cans with gaskets. CONSTITUTION:A liquid seal agent 4 is coated on cuffed bottoms 1b of negative electrode tubes 1c-1f, which are inserted into a tube 9 made of thermoshrinking plastic at a constant distance. They are preheated to form constricted portions 9a-9c on the tube 9, which is then cut at these portions. Each portion is further heated to be united in one body, thus producing a negative electrode can in one body, thus producing a negative electrode with a gasket. A negative electrode agent and an electrolyte are injected into this negative electrode can with a gasket to make up a negative electrode unit, which is incorporated in a positive electrode to form a button type silver oxide cell, etc. The button type cell using this thermoshrinking material is excellent in the leakage resistance. |
