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 LiAlLaZrMO, 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 LiPSX, 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.
