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.
