PURPOSE:To improve a charge/discharge cycle life of a secondary battery provided with organic electrolyte comprising electrolyte dissolved in organic solvent. CONSTITUTION:Metal having lithium storing and discharging ability, that is alloy of aluminum and lithium, for example, is used as active material for a negative electrode 5, and organic electrolyte comprising lithium perfluoromethyl sulfonyl imide [LiN(CF3SO2)2] dissolved in organic solvent comprising three components of propylene carbonate, ethylene carbonate, and diethylene carbonate mixed with each other, for example, is held on a separator 6. A positive electrode 4 is provided, thereby a secondary battery is composed. |
