  "textContent": "Provided is a method for producing a lithium secondary battery in which localized precipitation of a foreign metal in the negative electrode can be reliably suppressed in a shorter time, regardless of, for instance, electrode type or electrode variability. The production method is a method for producing a secondary battery that includes a positive electrode provided with a positive electrode active material layer, a negative electrode provided with a negative electrode active material layer, and a nonaqueous electrolyte. The method comprises a step of constructing a cell including the positive electrode, the negative electrode and the nonaqueous electrolyte; a micro-charging step of performing charging over one hour or longer, up to 0.01% to 0.5% of the capacity of the constructed cell, in a state of charge such that a positive electrode potential is equal to or higher than an oxidation potential of iron (Fe), and a negative electrode potential is equal to or higher than a reduction potential of iron (Fe), and maintaining the state of charge; and a step of performing an initial conditioning charging.",
