Abstract
An opening of a packaging member containing a positive electrode, a negative electrode, and a non-aqueous electrolyte solution is temporarily sealed to produce a temporarily sealed battery. The temporarily sealed battery is initially charged so that a negative electrode potential becomes higher than 0.8 V and 1.4 V or lower (versus Li/Li+), and is stored in an atmosphere of 50° C. or higher and lower than 80° C. Thereafter, gas is discharged from the temporarily sealed battery, and the temporarily sealed battery is finally sealed to produce a non-aqueous electrolyte secondary battery. Lithium titanate with a spinel structure, lithium titanate with a ramsdellite structure, Li4+xTi5O12, Li2+xTi3O7, a titanic acid compound given by the general formula H2TinO2n+1, or a monoclinic titanium composite oxide such as a bronze titanium oxide may be used as the titanium composite oxide.
