the positive electrode for a solid-state secondary battery includes a positive electrode current collector and a positive electrode active material layer, wherein the positive electrode active material layer includes a positive electrode active material, a solid electrolyte, a binder, and a conductive auxiliary agent, an amount of the positive electrode active material based on 100 wt % of the positive electrode active material layer is greater than or equal to 85 wt % and less than or equal to 92 wt %, an amount of the solid electrolyte based on 100 wt % of the positive electrode active material layer is greater than or equal to 7 wt % and less than or equal to 15 wt %, when the amount of the positive electrode active material in the positive electrode active material layer is 100 wt %, an amount of the binder in the positive electrode active material layer is greater than or equal to 0.1 wt % and less than or equal to 1.0 wt %, when the amount of the solid electrolyte in the positive electrode active material layer is 100 wt %, an amount of the conductive auxiliary agent in the positive electrode active material layer is greater than or equal to 0.1 wt % and less than or equal to 10 wt %.
provided is a positive electrode for a solid-state secondary battery, which suppresses the internal resistance of a battery while causing a solid-state secondary battery to have a sufficiently high energy density, and thus satisfies high levels with respect to both capacity and output.
