Nonaqueous electrolyte solution and nonaqueous electrolyte battery

A nonaqueous electrolyte battery, comprising:

• a positive electrode capable of absorbing and releasing metal ions;
• a negative electrode capable of absorbing and releasing metal ions, and
• a nonaqueous electrolyte solution, comprising:
• a compound represented by Formula (A),
• a cyclic carbonate having unsaturated carbon-carbon bond, and
• at least one kind of a compound selected from the group consisting of a compound represented by formula (B) and a compound represented by formula (C),
• wherein
• the negative electrode comprises an active material containing metal particles alloyable with Li, and graphite,
• the metal particles alloyable with Li are composed of Si or a Si metal oxide,
• a content of the metal particles alloyable with Li is 0.1% by mass or higher and 25% by mass or less with respect to a total amount of the negative electrode active material,
• a content of the cyclic carbonate having unsaturated carbon-carbon bond with respect to a total amount of the nonaqueous electrolyte solution is 0.01% by mass or higher and 1.5% by mass or less, and
• when the nonaqueous electrolyte solution contains only one of the compound represented by Formula (B) and the compound represented by Formula (C), the content of the compound represented by Formula (B) or (C) with respect to the total amount of the nonaqueous electrolyte solution is 0.01% by mass or higher and 0.49% by mass or less, and
• when the nonaqueous electrolyte solution contains both of the compounds represented by Formulae (B) and (C), a total content of the compound represented by Formula (B) and the compound represented by Formula (C) with respect to the total amount of the nonaqueous electrolyte solution is 0.01% by mass or higher and 0.80% by mass or less:
• wherein m and n are each independently an integer of 1 to 3,
• wherein R1 to R3 are each independently an optionally substituted hydrocarbon group having 1 to 10 carbon atoms with the proviso that at least one of R1 to R3 is a hydrocarbon group having an unsaturated carbon-carbon bond,
• wherein Q is a hydrocarbon group having 3 to 20 carbon atoms comprising a cycloalkyl group.
