Claim:
1. A method for producing a non-aqueous secondary battery comprising: constructing a preconditioning cell that comprises a positive electrode comprising a positive electrode active material, a preconditioning electrolyte solution comprising a supporting salt and a fluorine containing non-ionic compound, and a preconditioning negative electrode; carrying out a preconditioning process by charging the preconditioning cell and allowing the fluorine-containing non-ionic compound to be decomposed at the positive electrode to form coatings on surfaces of the positive electrode active material; and constructing a non-aqueous secondary battery, using the positive electrode active material having the coatings formed, a non-aqueous electrolyte solution different from the preconditioning electrolyte solution, and a negative electrode comprising a negative electrode active material.
