(a) Raman spectra in the range of 330–480 cm−1 for Li2S-P2S5 glasses. Black, blue and green lines represent 75Li2S, 70Li2S and 67Li2S glasses, respectively. The spectra in the range of 400–560 cm−1 are enlarged in the inset for clarity. (b) Spectral decomposition of Raman spectrum for 70Li2S glass. Blue line, experimental data; dotted lines, the fitting result for all PS polyhedra (right-blue), PS4 (black), P2S7 (red) and P2S6 (blue) anions. (c) PSx polyhedral fractions for Li2S-P2S5 glasses derived from Raman spectra (open marks) and DFT/RMC model (filled marks).
