PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery with good low temperature characteristics and high cycle characteristics. SOLUTION: The battery has a positive electrode capable of doping/undoping lithium ions, a negative electrode made of metallic lithium or a material capable of doping/undoping lithium ions, and a nonaqueous electrolyte prepared by dissolving a lithium salt electrolyte in a nonaqueous solvent. The nonaqueous solvent contains a cyanoethoxy compound represented by the general formula, R-(OC2H4CN)n. In the formula, n=1-4, R is either one of the following structures. R:CmH2m+2-n, CmH2m+2-n(OC2H4)p, CmH2m+2nCO, and CmH2m+2nOCO (m=1-3, P=1-4). |
