This invention discloses a rapidly synthesizable chloride solid electrolyte, its preparation method, and its applications. The chloride solid electrolyte of this invention contains anions, cations, and water of crystallization, wherein the anions include Cl... ‑ and at least one of the following ions: F ‑ OH ‑ O 2‑ CO3 2‑ S 2‑ SO4 2‑ PO4 3‑ N 3‑ NO3 3‑ The cation includes Zr. 4+ Li + and at least one of the following ions: H + Ca 2+ Cu 2+ Fe 2+ Mg 2+ Zn 2+ Na + Al 3+ Zr 4+ Fe 3+ Co 2+ Ba 2+ Mn 2+ This invention prepares the chloride solid electrolyte by introducing crystalline hydrates, which improves the lithium-ion conductivity of the chloride solid electrolyte, broadens the electrochemical stability window and the thermodynamic stability potential of the electrolyte, enabling the cathode / electrolyte interface to stably transport lithium ions under high voltage (4.5 V), making it more suitable for high-capacity, high-voltage all-solid-state batteries.

A niobium-containing silver-germanium sulfide-type solid electrolyte composition with enhanced air stability and enhanced dendrite suppression is described. The niobium-containing silver-germanium sulfide-type solid electrolyte composition comprises a silver-germanium sulfide-type crystal structure and the general formula Li. 5.5 (P 1‑i Nb i (S) 4.5‑ j O j )X 1.5 Co-substituted argyrophthalite-type solid electrolyte particles, wherein: X is at least one halogen; i is in the range of 0.01 to 0.12; and j is in the range of 0.01 to 0.6. Co-substituted argyrophthalite-type solid electrolyte particles can be used in electrochemical cells, such as all-solid-state lithium-ion batteries or semi-solid-state lithium-ion batteries. In some aspects, the co-substituted particles are formed from niobium oxide, lithium sulfide, phosphorus pentasulfide, and lithium halide. Additionally or alternatively, the co-substituted particles are formed by ball milling.
