Provided is a nonaqueous electrolyte solution battery with dramatically improved battery characteristics. A nonaqueous electrolyte solution battery prepared by using a nonaqueous electrolyte solution comprising (I) an aromatic carboxylic acid ester compound represented by General Formula (1) below; and (II) specific compounds, is improved in charge-discharge characteristics at high current densities, durability performance during high-temperature storage and overcharge characteristics.
(in General Formula (1), A 1 is -R 1 or -OR 1 , with R 1 being an optionally substituted hydrocarbon group with 10 or fewer carbon atoms; A 2 is an optionally substituted aryl group; each of j and k is independently 0 or an integer greater than 0, and either j or k is an integer not less than 1; and when k ‰¥ 1, A 1 is -OR 1 , while when k = 0, A 3 is -R 1 ; and the case of j = 1, k = 0 is not allowed). |
