PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery with good load characteristics and high cycle characteristics. SOLUTION: A nonaqueous electrolyte battery has a negative electrode 1, a positive electrode 2, and a nonaqueous electrolyte. The negative electrode 1 is made of metallic lithium, a lithium alloy, or a material (a carbon material for example) capable of doping/undoping lithium. The positive electrode 2 is made of a composite oxide of lithium and a transition metal, for example. The nonaqueous electrolyte contains 1,3-dimethyl-2-imidazolinon. By adding 0.01 vol.% or more but less than 1 vol.% 1,3-dimethyl-2-imodazolinon, the load characteristics of the battery is greatly increased. The battery constitution is allowable to be a regular lithium ion battery, a polymer solid electrolyte battery, or a polymer gelled electrolyte battery. |
