摘要: An active material is provided for use in a solid-state battery. The active material exhibits at least one peak in the range of 0.145 to 0.185 nm and at least one peak in the range of 0.280 to 0.310 nm in a radial distribution function obtained through measurement of an X-ray absorption fine structure thereof. In the particle size distribution, by volume, of the active material obtained through a particle size distribution measurement by laser diffraction scattering method, the ratio of the absolute value of the difference between the mode diameter of the active material and the D10 of the active material (referred to as the “mode diameter” and the “D10” respectively) to the mode diameter in percentage terms, (|mode diameter−D10|/mode diameter)×100, satisfies 0%

摘要: Disclosed is an active material that can reduce an interface resistance with a sulfide solid electrolyte and improve the battery performance. The active material exhibits at least one peak in the range of from 0.145 nm to 0.185 nm and at least one peak in the range of from 0.28 nm to 0.31 nm in a radial distribution function obtained through measurement of an X-ray absorption fine structure of the active material. The active material is for use in a solid-state battery. The active material preferably has a core particle, and a coating layer located on the surface of the core particle.
