PROBLEM TO BE SOLVED: To practically prevent the corrosion of a vessel and/or a collector made of aluminum, and provide a high energy capacity by using both predetermined sulfonate and lithium salt as the electrolyte salt of an electrolyte layer together. SOLUTION: As the electrolyte salt of an electrolyte layer, both at last one kind selected out of a group composed of sulfonate shown by a predetermined formula and a salt except lithium sulfonate are used together. In the case of a button, LiN(CF3 SO2 )2 , (1)LiC(CF3 SO2 )3 , (2), LiOCF3 SO2 (3), LiCRq (CF3 SO2 )n (4) are used as the predetermined formulas. (In the formula, R is an alkyl group, q and n are positive integers. Where, the sum of q and n is 3.) As lithium salt except lithium sulfonate, LiX (X is selected out of a group composed of PF6 , SbF6 , AsF6 , ClO4 , and AlCl4 .) is used. Thereby, in a batter formed material made of aluminum or mainly made of the aluminum, a vessel is not allowed to react with the lithium to realize high energy. |
