PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte battery, which combines a good low-temperature performance, high energy density, and the outstanding high- temperature preservation ability. SOLUTION: In the non-aqueous electrolyte battery constituted by at least, a positive electrode, which uses a positive-electrode active material as a main composition component, a negative electrode, which uses a negative-electrode carbonaceous material as the main composition component, and a non-aqueous electrolyte, the above negative-electrode carbonaceous material contains 5% or more of a rhombohedral system structure, and the above non-aqueous electrolyte contains at least carbonate, in which has double bonds of carbon and carbon.
