  • Lithium ion conductive composite solid electrolyte and solid-state battery using the same
    Patent number: 12107213
    Abstract: The present invention provides a lithium ion conductive composite solid electrolyte including an oxide-based crystalline solid electrolyte and a sulfide-based solid electrolyte, wherein the oxide-based solid electrolyte is a garnet-type solid electrolyte represented by a general formula of Li7-3y-zAlyLa3Zr2-zMzO12, wherein M is at least one element selected from the group consisting of niobium (Nb), tantalum (Ta), and tungsten (W), y satisfies 0?y?1, and z satisfies 0?z<2, the sulfide-based solid electrolyte is an argyrodite-based ceramic represented by a general formula of Li7-aPS6-aXa, wherein X is at least one element selected from the group consisting of chlorine (Cl), bromine (Br), and iodine (I), and a satisfies 0?a?2, and the oxide-based solid electrolyte and the sulfide-based solid electrolyte are mixed in a weight ratio of 5.1:4.9 to 8:2.
    Type: Grant
