Abstract
A composite solid electrolyte with excellent formability and chemical stability and high lithium ion conductivity. The composite solid electrolyte may comprise an oxide-based solid electrolyte and a sulfide-based solid electrolyte, wherein the oxide-based solid electrolyte is (Li7-3Y-Z, AlY)(La3)(Zr2-Z, MZ)O12 (where M is at least one element selected from the group consisting of Nb and Ta; Y is a number in a range of 0≤Y<0.22; and Z is a number in a range of 0≤Z≤2), and wherein the sulfide-based solid electrolyte is VLiX-(1−V)((1−W)Li2S-WP2S5) (where X is a halogen element; V is a number in a range of 0<V<1; and W is a number in a range of 0.125≤W≤0.30).
