The charging method is a multistep secondary battery charging method comprising first charging in which a secondary battery is charged at a first current density I1, and second charging in which the secondary battery is charged at a second current density I2 which is larger than the first current density I1, wherein, when a roughness height of an anode current collecting foil-side surface of a solid electrolyte layer is determined as Y (μm) and a thickness of a roughness coating layer is determined as X (μm), in the first charging, the secondary battery is charged at the first current density I1 until X/Y reaches 0.5 or more."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for charging secondary battery","description":"Provided is a method for charging a secondary battery configured to both suppress battery short circuits and to reduce battery charging time.
