Abstract: An electrode mixture includes a sulfide solid electrolyte and a carbon-containing material having contact with the sulfide solid electrolyte. An intensity ratio C/S determined from a spectrum obtained by analyzing the electrode mixture by Auger electron spectroscopy satisfies 0.2≤C/S≤1, where C is an intensity of a peak in the spectrum which corresponds to carbon included in the carbon-containing material, and S is an intensity of a peak in the spectrum which corresponds to sulfur included in the sulfide solid electrolyte.

Abstract: An electrode material includes: active material particles each containing nickel; and cover layers which cover the surfaces of the respective active material particles, the cover layers each containing niobium. In an X-ray photoelectron spectrum of the electrode material, the ratio A/B of an intensity A of a peak belonging to Nb3d to an intensity B of a peak belonging to Ni2p satisfies 0
