    • The present invention provides a lithium secondary battery having excellent battery cycle property, electrical capacity, storage characteristic and other battery characteristics for a long period of time, and a nonaqueous electrolytic solution which is usable for the lithium secondary battery.A nonaqueous electrolytic solution in which an electrolyte salt is dissolved in a nonaqueous solvent, comprising (i) a dicarbonyl compound represented by the general formula (I), or (ii) a dicarbonyl compound represented by the general formula (II) and vinylene carbonate and the like in the nonaqueous electrolytic solution. (wherein R1 represents a hydrogen atom, an alkyl group, an alkenyl group, a phenyl group or the like; and X represents a hydrogen atom, an R2 group or an OR2 group. R2 represents an alkyl group, an alkenyl group, a phenyl group or the like.) (wherein R1 and X are the same as above; Y and Z represents a hydrogen atom, an R2 group, an OR2 group, a COR2 group or a CH2COR2 group; and n is 1 to 6.).
    • 本发明提供一种长时间具有优异的电池循环性能,电容量,储存特性等电池特性的锂二次电池和可用于锂二次电池的非水电解液。 其中电解质盐溶解在非水溶剂中的非水电解液,包括(i)由通式(I)表示的二羰基化合物或(ii)由通式(II)表示的二羰基化合物和碳酸亚乙烯酯 在非水电解液中。 (其中R1表示氢原子,烷基,烯基,苯基等; X表示氢原子,R2基或OR2基,R2表示烷基,烯基,苯基 基团等)(其中R1和X与上述相同; Y和Z表示氢原子,R2基团,OR2基团,COR2基团或CH2COR2基团; n为1至6.)。
