Advancing Sulfide Solid Electrolytes via Green Li2S Synthesis

A Source Data file and DFT calculations data for NCOMMS-25-12375C. The DFT calculation data for metathesis and sulfurization reaction energetics, online coupled TG/DTA-FTIR and TG/DTA-MS spectra for thermal analysis, XRD patterns and Rietveld refinement results for structural characterization, Raman spectra, polarization current-time curves, electrochemical impedance spectroscopy (EIS) data, charge-discharge curves, rate capability data, and cycling stability measurements for all solid electrolyte and battery samples are provided as individual Excel files corresponding to each figure in the manuscript. Additional supplementary characterization data including ICP analysis and carbon content measurements are also available in the same repository.
