  "textContent": "A manufacturing method for a non-aqueous electrolyte secondary battery includes preparing a battery assembly, and performing an initial charging on the battery assembly. In the initial charging, a differential capacity curve of the battery assembly has a first peak voltage at which a first layer is formed on the electrode body and a second peak voltage at which a second layer is formed on the electrode body. The initial charging includes forming the first layer by stopping charging for a first stop time after charging to a first specified voltage that is set between the first peak voltage and the second peak voltage, and forming a second layer with charging performed to a second specified voltage that is set higher than the second peak voltage after forming the first layer.",
