Manufacturing method of the production method and laminated battery of a lithium secondary battery

Volume energy density and weight energy density to provide a method of manufacturing a lithium secondary battery is improved. It is formed on the bonding surface of the exterior film the entire conductor layer having an electrode terminal electrically connected to the current collector and the current collector of the cell has flexibility and barrier properties, the conductor layer and the outer package film There integrated complex is produced. The current collector located inside the bonding area, at least a portion of the electrode terminals is external to the lamination area. The positive electrode active material precursor layer, electrolyte precursor layer and the anode active material precursor layer is added to the complex combined current collector and the plane position, the positive electrode active material precursor layer, electrolyte precursor layer and the anode active material precursor crosslinking treatment of the material layer is performed. We are stuck together area bonding, the outer film is bonded, the cell is sealed. Crosslinking treatment may be omitted.
