Figure 4. (A) The CV test on the Li-S cells using different separators under a scan rate of 0.2 mV s^-1. (B) Diffusion coefficient calculation based on the relationship of peak current and square of sweep rate from CV profiles at different sweep rates. (C) Galvanostatic discharge and charge curves under a rate of 0.2 C. Tafel plots corresponding to the reduction reactions (D) from elemental sulfur to Li₂S_n and (E) from Li₂S_n to Li₂S. (F) Relative activation energy evolution of S₈-Li₂S_n-Li₂S conversion reactions based on different separators. (G) Adsorption energies and (H) Gibbs free energy profiles of LiPSs on the surface of NbN (200) by DFT method.
