Positive Electrode For All Solid State Battery, And All Solid State Battery Comprising Same

Abstract: The present invention relates to a positive electrode for an all-solid-state battery and an all-solid-state battery comprising same. More specifically, in the present invention, the positive electrode active material layer includes a positive electrode active material, a sulfide-based solid electrolyte, a conductive material, and a porous carbon additive. By allowing the particle diameter of the porous carbon additive to be included between the particle diameter of the positive electrode active material and the particle diameter of the sulfide-based solid electrolyte, the interface between the positive electrode active material and the sulfide-based solid electrolyte can be increased and at the same time the porosity of the entire positive electrode can be reduced, thereby exhibiting the effect of increasing the energy density of a cell without decreasing the cell performance while maintaining the conductivity of a bipolar electrode.
