Abstract:
An object is to provide a nonaqueous electrolyte secondary battery that has an SEI coating with a special structure and has excellent battery characteristics. As an electrolytic solution of the nonaqueous electrolyte secondary battery, an electrolytic solution containing: a salt whose cation is an alkali metal, an alkaline earth metal, or aluminum and whose cation is an alkali metal, an alkaline earth metal, or aluminum; and an organic solvent having a heteroelement is used, wherein, Is>Io is satisfied, and an S,O-containing coating having an S═O structure is formed on the surface of a positive electrode and/or a negative electrode. Alternatively, the above described electrolytic solution is used, and, as a binding agent for negative electrodes, a binding agent formed of a polymer having a hydrophilic group is used.

Claim (Index 1):
A nonaqueous electrolyte secondary battery, comprising: a negative electrode, an electrolytic solution, and a positive electrode, wherein\n one of the following Condition A or Condition B is satisfied: Condition A: regarding an intensity of a peak derived from the organic solvent in a vibrational spectroscopy spectrum of the electrolytic solution, Is>Io is satisfied when an intensity of an original peak of the organic solvent is represented as Io and an intensity of a peak resulting from shifting of the original peak is represented as Is, or Condition B: d/c obtained by dividing a density d (g/cm 3 ) of the electrolytic solution by a salt concentration c (mol/L) of the electrolytic solution is within a range of 0.15\u2264d/c\u22640.71, the electrolytic solution contains a salt whose cation is an alkali metal, an alkaline earth metal, or aluminum, and an organic solvent having a heteroelement, the negative electrode includes a binding agent formed of a polymer having a hydrophilic group, the salt of the electrolytic solution consists of the salt whose cation is an alkali metal or an alkaline earth metal, and the organic solvent of the electrolytic solution is selected from the group consisting of nitriles, tetrahydrofuran, 1,2-dioxane, 1,3-dioxane, 1,4-dioxane, 2,2-dimethyl-1,3-dioxolane, 2-methyltetrahydropyran, 2-methyltetrahydrofuran, crown ethers, carbonates, amides, isocyanates, esters, epoxies, oxazoles, ketones, acid anhydrides, sulfones, sulfoxides, nitros, furans, cyclic esters, aromatic heterocycles, non-aromatic heterocycles, and phosphoric acid esters.
