PURPOSE:To suppress exothermic capacity inside a battery and prevent abnormal increase in the battery temperature by arranging a halogenated compound, which suppresses decomposition of a solvent in contact with generating elements when the battery temperature attains a specific temperature, to be isolated from the generating elements in normal condition. CONSTITUTION:In a battery equipped with generating elements containing a negative electrode and a positive electrode with light metal as active substance and nonaqueous electrolyte comprising at least an organic solvent and at least a solute, a halogenated compound is arranged usually being isolated from the generating elements, to suppress decomposition of the solvent in contact with the generating elements when the battery temperature attains a specific temperature. The arrangement can prevent the battery temperature from abnormally increasing, even under abnormal environment such as high atmospheric temperature. |
