PURPOSE:To manufacture an even Li alloy for negative electrode easily and to improve the preservative property in a high temperature ambiance by carrying out a transformation discharge at a temperature scope 40-70 deg.C after assembling the device. CONSTITUTION:This dischargeable electrochemical device consists of a case 1 being a positive electrode terminal concurrently, a sealing plate 2 being a negative electrode terminal, a gasket 3 made of propylene, a positive electrode 4, a positive electrode collector 5, a separator 6, a negative electrode 7, a nickel net 8, a negative electrode Li 9, and an electrolyte made by solving lithium borofluoride in a mixture solvent of the same volumes of propylene carbonate and gamma-butyrolactone at the ratio 1mol per l. The positive electrode 4 is formed by mixing and kneading 40 wt.pt. of active carbon particles, 10 wt.pt. of acetylene black, and 20 wt.pt. of solid component of the water dispersion of a fluorine resin, and transferring to a titanium plate after making in a sheet form by passing through two rolls. After the device is assembled, a transformation discharge is carried out at the temperature scope 40-70 deg.C. |
