| description | PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery which includes a negative electrode having a negative electrode active material which lithium ions can be adsorbed by or desorbed from at a potential of 1.2 V or higher to a lithium potential of lithium titanate or the like, and has a superior low-temperature output property.SOLUTION: A nonaqueous electrolyte battery comprises: a negative electrode having a negative electrode active material which lithium ions can be adsorbed by or desorbed from at a potential of 1.2 V or higher to a lithium potential; and an electrolytic solution. The electrolytic solution includes carbonic ester having no carbon-carbon double bond. Supposing that the volume of the carbonic ester having no carbon-carbon double bond is 100, the percentage of the volume of the carbonic ester which cyclic carbonate accounts for is "a", and the volume percentage of EMC is "c", the relation given by a+c=100 holds, where 0≤a≤10 and 90≤c≤100.
【課題】チタン酸リチウム等のリチウム電位に対して１．２Ｖ以上の電位にてリチウムイオンが挿入・脱離する負極活物質を有する負極を備え、優れた低温出力特性を有する非水電解質電池を提供する。【解決手段】リチウム電位に対して１．２Ｖ以上の電位にてリチウムイオンが挿入・脱離する負極活物質を有する負極を備えた非水電解質電池において、電解液を構成する炭素−炭素二重結合を有さない炭酸エステルの体積を１００とし、該炭酸エステルの体積に占める環状炭酸エステルの体積割合をａ、ＥＭＣの体積割合をｃとしたとき、ａ＋ｃ＝１００であり、かつ０ ａ １０、９０ ｃ １００を同時に満たす非水電解質電池。【選択図】なし |
