POSITIVE ELECTRODE FOR ALL-SOLID-STATE BATTERY AND ALL-SOLID-STATE BATTERY COMPRISING SAME

Disclosed is a positive electrode for all-solid-state battery and an all-solid-state battery comprising same. More specifically, the positive electrode active material layer of the positive electrode comprises a positive electrode active material, a sulfide-based solid electrolyte, and a conductive material, wherein the particle diameter of the conductive material is between the particle diameter of the positive electrode active material and the particle diameter of the sulfide-based solid electrolyte, which may thereby increasing the contact interface between the positive electrode active material and the sulfide-based solid electrolyte while decreasing the porosity of the positive electrode as a whole, so that the conductivity of the positive electrode can be maintained and the effect of increasing the energy density of the cell without a decrease in cell performance can be achieved.
