Solid electrolyte laminated sheet, all-solid state secondary battery, and manufacturing method for all-solid state secondary battery

Abstract

There is provided a solid electrolyte laminated sheet including a sheet-shaped porous support internally containing an inorganic solid electrolyte and a solid electrolyte layer internally containing an inorganic solid electrolyte, in which a void ratio of the porous support is 20% or more, and a void ratio of the solid electrolyte layer is smaller than the void ratio of the porous support. There are also provided a manufacturing method for an all-solid state secondary battery in which this solid electrolyte laminated sheet is used to carry out pressurization and manufacturing while adjusting void ratio of the porous support and the solid electrolyte layer, and an all-solid state secondary battery.
