To investigate the kinetics improvement during the SRR associated with the BNC additives, a series of cyclic voltammetry (CV) experiments was undertaken within three distinct electrolyte systems, namely, baseline (lithium bis(trifluoromethane)sulfonimide (LiTFSI)/LiNO3 in DME/DOL), 0.01 M and 0.11 M BNC-containing electrolytes. CV experiments of Li-S halfcells were performed using CR2032 coin cell. Figures and and depict the characteristics CV curves of Li-S batteries. The CV curves reveal two cathodic peaks and two anodic peaks, consistent with the conversion between long-chain to middle-chain polysulfides and middle-chain to short-chain polysulfides and vice versa. Interestingly, the 0.01 M BNCcontaining electrolyte exhibits a larger potential difference between A2 and B2 peaks of 0.775 V at a scan rate of 0.5 mV/s and 0.403 V at 0.05 mV/s compared to the baseline electrolyte of 0.646 V at 0.5 mV/s and 0.356 V at 0.05 mV/s (Figures and). Furthermore, it displays a broader peak at A2 peak (Figure ) with lower intensity (Figures ). Given that the A2 peak is attributed to short-chain polysulfides conversion, this generally indicates less favorable kinetics in the studied electrochemical system. Given BNC's reactivity with polysulfides and its subsequent anchoring effect, the resulting product displays reduced electrochemical activity compared to its short-chain polysulfide counterpart. This irreversibility induced by the product introduces a partial hindrance to electron transfer during polysulfide conversion, subsequently elevating overall electrochemical resistance. Consequently, this phenomenon manifests in a reduced peak intensity of A2 and a larger differential potential between A2 and B2 peaks.
