PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte capable of achieving high capacity, high output and high stabilization of a secondary battery by stabilizing the surface of an aluminum current collector and suppressing rise in viscosity of the electrolyte.SOLUTION: A nonaqueous electrolyte includes lithium salt and an electrolyte additive. The electrolyte additive is capable of dissolving the lithium salt, has a fluorine group, has a structure in which HF or Fis separated, and is a compound or an equilibrium product represented by XCHCF-Y (formula 1). |
