The morphologies of LPSCl, Li3InCl6, and Li3InCl6 coated NCA (LIC@NCA) were characterized by a FEI Apreo emission scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS). X-ray diffraction (XRD) were performed on a Bruker Davinci 1 with a Cu Kα radiation (λ = 1.54178 Å) at room temperature with an airtight holder to avoid air exposure. The data were collected by scanning 1s per step with a step width of 0.02 from 10° to 70° (2θ). The data for the X-ray refinement were collected by scanning 5s per step with one step of 0.02° from 10 to 70° (2θ). The XRD refinement was done by using the software TOPAS.
