Abstract
The present invention provides: a nonaqueous electrolyte solution which is used in a nonaqueous electrolyte battery having a low initial resistance value; and a compound which is contained in this nonaqueous electrolyte solution. A nonaqueous electrolyte solution according to the present invention contains a compound represented by formula (1), a solute and a nonaqueous organic solvent. In general formula (1), each of Rand Rrepresents PO(R)or SOR, and Rf represents, for example, a fluorine atom; each of Rand Rrepresents, for example, a lithium ion, or alternatively Rand Rmay form a ring structure together with a nitrogen atom to which the moieties are bonded, and in this case, Rand Rform an alkylene group in combination with each other; an oxygen atom may be contained between carbon atom-carbon atom bonds in the alkylene group; a side chain thereof may have an alkyl group; and an arbitrary hydrogen atom in the alkyl group and the alkylene group may be substituted by a fluorine atom.
