LYC (Li3YCl6) is a superionic conductor. Its conductivity is highly dependent on the crystal phase and synthesis method. Its ionic conductivity could be up to 0.5-1.5 mS/cm at room temperature. Certain optimized off-stoichiometric compositions or mixed-halide variants can achieve conductivities up to 7 mS/cm or higher. Li3YCl6 can exist in different polymorphs (e.g., trigonal or orthorhombic), often based on a hexagonal close-packed (hcp) anion arrangement. The substitution of three Li+ ions with one Y3+ ion creates two intrinsic lithium vacancies, which are the essential mobile charge carriers for fast Li+ transport. Conduction is often highly anisotropic, with the c-direction being the primary contributor to diffusivity.
