  • Composite active material, manufacturing method for composite active material, and lithium secondary battery including composite active material
    Patent number: 9929430
    Abstract: A composite active material including composite particles and a sulfide-based solid electrolyte is proposed. The composite particles contain active material particles and an oxide-based solid electrolyte. The active material particles contain at least any one of a cobalt element, a nickel element and a manganese element and further contain a lithium element and an oxygen element. The oxide-based solid electrolyte coats all or part of a surface of each of the active material particles. The sulfide-based solid electrolyte further coats 76.0% or more of a surface of each of the composite particles.
