PROBLEM TO BE SOLVED: To obtain a non-aqueous electrolyte battery which has an excellent high-temperature preservation property, high reliability and high energy density by suppressing the dissolution of the electrolyte inside the battery even in the case of being disposed to the high temperature in the square battery. SOLUTION: This battery comprises a negative electrode and a non-aqueous electrolyte which are sealed in a square battery can, and the non-aqueous electrolyte contains unsaturated cyclic carbonate and halogenate methoxybenzene group compound, in particular, vinylenecarbonate and 2,4-fluoroanisole. |
