PURPOSE:To make it possible to control deterioration in its low-temperature discharge property after it is preserved, by using lithium alloy in its negative electrode, in a nonaqueous type electrolyte battery using trifluoromethane sulfonic acid lithium as solute. CONSTITUTION:In a nonaqueous type electrolyte battery having trifluoromethane sulfonic acid lithium (LiCF3SO3) used as solute thereof, lithium alloy is used in its negative electrode 2. Since lithium alloy is low in activity when compared to lithium alone, reaction between fluorine ion ionized from LiCF3SO3 and lithium included in the lithium alloy is controlled even when it is preserved in a long period. Thus passivated coats may scarcely be generated on the surface of the negative electrode 2, so that deterioration in its low-temperature discharge property after it is preserved. |
