    • A non-aqueous electrolytic solutions which has self-distinguishing property, low reactivity to metal lithium and high withstand voltage is provided. The non-aqueous electrolytic solutions of the first invention comprise, as electrolyte, lithium salt preferably LiPF.sub.6 and, as solvent, phosphoric acid esters of the following general formula [1]; ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3, which may be the same or different, represent an alkyl group or an alkyl group substituted by one or more halogen atoms and at least one of R.sup.1, R.sup.2, and R.sup.3 represents an alkyl group substituted by one or more halogen atoms. The non-aqueous electrolytic solutions of the second invention comprise, as solvents for electrolyte, trimethyl phosphate, one or more linear carbonates represented by the following general formula [3]; ##STR2## (wherein R.sup.6 represents methyl or ethyl group and R.sup.7 represents a linear or branched alkyl group having 1 to 3 carbon atoms) and one or more cyclic carbonates and, as electrolyte, LiPF.sub.6 ; wherein content of the trymetyl phosphate is 1 to 10% by volume of the solvents for electrolyte. The non-aqueous electrolytic solution is suitable for a cell using carbon material capable of being doped and dedoped with lithium ions as a negative electrode active material and complexed oxide of lithium and a transition metal as a positive electrode active material.
    • 提供了具有自我辨别性,对金属锂的低反应性和高耐受电压的非水电解液。 第一发明的非水电解液包含作为电解质的锂盐,优选LiPF 6和作为溶剂的下列通式[1]的磷酸酯; 其中R 1,R 2和R 3可以相同或不同,表示烷基或被一个或多个卤素原子取代的烷基,并且R 1,R 2和R 3中的至少一个表示烷基 基团被一个或多个卤素原子取代。 第二发明的非水电解液包含作为电解质溶剂的磷酸三甲酯,由以下通式[3]表示的一种或多种直链碳酸酯; [3](其中R 6表示甲基或乙基,R 7表示碳原子数1〜3的直链或支链烷基)和一种或多种环状碳酸酯,作为电解质,LiPF 6; 其中磷酸三甲酯的含量为电解质溶剂的1〜10体积%。 非水电解液适用于能够掺杂和去掺杂锂离子作为负极活性物质的锂电池和锂和过渡金属的复合氧化物作为正极活性物质的电池。
