Figure 6: Lithium ion diffusion properties of the electrode at various voltage scan rates.

Plot of CV peak current of (a) the cathodic reaction 1 (S₈→Li₂S₄), (b) the cathodic reaction 2 (Li₂S₄→Li₂S), (c) the anodic reaction 1 (Li₂S→Li₂S₄) and (d) the anodic reaction 2 (Li₂S₄→S₈) versus the square root of scan rates.
