Abstract
In the present disclosure, a positive electrode layer used in an all-solid-state battery includes a positive electrode active material, a sulfide solid electrolyte, and a coated sulfide solid electrolyte having a coating layer covering a surface of the sulfide solid electrolyte and containing a metal sulfate, and in an S2p spectrum obtained by X-ray photoelectron spectroscopy (XPS) on the coated sulfide solid electrolyte, a ratio (P2/P1) of an intensity P2 of a peak appearing near 163 eV to an intensity P1 of a peak appearing near 167 eV is 0.15 or more and less than 0.36, thereby solving the above problem.
