ENERGY-STORING DEVICE

摘要

PURPOSE:To eliminate accident due to leakage of electrolyte by constituting an energy-storing device in such a manner to utilize a highly improved airtightness owing to glass-metal combination or metal-metal combination. CONSTITUTION:A glass-sheet ring 3 is inserted between a circular electrode plate 1 and a donut-like conductive plate (Fe-Cr stainless) 2 and both are adhered by calcination to form a cover 4. And the cover 4 and a case part 11 are joined by using the laser sealing method with YAG laser to an outer periphery part 13. Thus, since the so called hermetic seal type both-electrode insulation construction and the metal-combination such as laser sealing are used, improved airtightness of electronic parts or cells can be realized. Thus, a highly reliable coin-type electronic parts without any leakage of electrolyte can be obtained.
