a–c Contour plots of CV patterns of Li||S batteries with GSCC binder in the 0.1–0.5 mV s−1 scan rate range. The calculations of Li+ diffusion coefficients at different voltages during (d) charging. and e discharging. In situ Raman spectra of battery with (f) PVDF and g GSCC binder during discharging at 0.2 C (335 mA g−1) and the corresponding contour maps (Both color scales are 0–2500). h Adsorption energies of PVDF and GSCC for various sulfur species (S8 to Li2S). i Gibbs free energy diagrams for the conversion of S8 to Li2S based on electrodes with different binders, inset illustrates the optimized adsorption configurations of GSCC with different sulfur species.
