PURPOSE:To obtain a battery having large discharge capacity, a long cycle life and moreover a small self-discharge rate by an electrolytic liquid wherein a carbonate compound, a lactone compound and an ether compound or their mixture are added to a composite of a macro-molecule and an electrolyte in the range of 5-50 weight%. CONSTITUTION:A carbonate compound, a lactone compound, an etherr compound or their mixture are added to a composite of a macro-molecule and an electrolyte in the range of 5-50 weight% to form an electrolytic liquid. When the carbonate compound, the lactone compound or the ether compound are added to a solid electrolyte made of a composite of the macro-molecule and an alkaline metal electrolyte, it has a remarkable to improve electric conductivity of the electrolyte and moreover a wide stability range while having sufficient reversibility and stable acting even when using an alkaline metal, an alkaline metal alloy, an (n) type conductive macro-molecule or their composite as a negative electrode. Thereby, charge-discharge can be performed with a long cycle life and moreover with relatively high current density. |
