PURPOSE:To suppress the transudation of electrolyte and to improve the leakage resistance of cell by providing sealing material between the cathode case and the packing and by heating it. CONSTITUTION:The surface of packing 7 is coated with toluene in which a mixture of blown asphalt and polybuten is dissolved, the packing and cathode case are fit on each other, and heated at 150 deg.C for three minutes, the sealing material is melted to completely fix the case and packing to each other in a body. In this way, the leakage resistance of cell can be improved. |
