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

Abstract: Provided are a positive electrode for an all-solid-state battery having adjusted compositional properties related to a carbon-based conductive material, and an all-solid-state battery comprising same. The all-solid-state battery comprises a positive electrode active material, a carbon-based conductive material, a binder, and a mineral-based solid electrolyte, wherein the carbon-based conductive material is a fibrous carbon-based conductive material having a length of 1 µm to 100 µm. The fibrous carbon-based conductive material can improve the initial discharge efficiency of an all-solid-state battery when used by mixing with the positive electrode active material in an appropriate ratio, as well as improve the capacity retention rate when discharging at a high rate of 0.5C or more.
