To further understand the impact of BNC, potentiostatic discharge experiments were designed to investigate the nucleation and growth of Li2S, a process characterized by a liquidsolid phase transition, representing the phase with the highest reaction energy barrier in the discharge process as shown in Figures and. Interestingly, the 0.01 M BNC-containing electrolyte possesses a higher Li2S nucleation response current and earlier nucleation time compared to the baseline. Additionally, the Li2S nucleation capacity in the 0.01 M BNCcontaining electrolyte exceeded that of the baseline by approximately 30 mAh/gsulfur. These findings suggest that BNC promotes the nucleation and growth of Li2S, thereby facilitating the conversion of short-chain polysulfides. However, during the charge process, both electrolytes exhibited nearly identical Li2S dissolution capacities of around 488 mAh/gsulfur (Figures and), indicating that BNC primarily enhances the kinetics of discharge process over the charge process. This observation is consistent with the results obtained from Randles-Sevcik analysis of peaks B1 and B2 as shown in Figure .
