a–c XANES (a), EXAFS (b), and FT-EXAFS (c) for xLi2O-TaCl5 amorphous SEs, as well as Ta2O5 and TaCl5 at Ta L3-edge. d, e, g, h WT spectra of 1.2Li2O-TaCl5 (d), 1.4Li2O-TaCl5 (e), 1.6Li2O-TaCl5 (g), and 1.8Li2O-TaCl5 (h) at Ta L3-edge with a k2 weighting. f, i The schematics of the local structures in superionic xLi2O-TaCl5 amorphous SEs (x = 1.2 and 1.4 in (f); x = 1.6 and 1.8 in (i)). (The local structures mainly display the coordination and possible geometry of xLi2O-TaCl5 amorphous SEs. Bond angles and Li-ion numbers are not accurate.)
