Even at a high C-rate process (1C), the 0.01 M BNC-containing electrolyte still holds a higher specific capacity of 354.27 mAh/gsulfur compared to the baseline of 243.65 mAh/gsulfur and 0.11 M BNC-containing electrolyte of 151.13 mAh/gsulfur. Consequently, the addition of 0.01 M BNC allows the entire electrochemical system to withstand the substantial mechanical stress induced by rapid Li intercalation at high C-rates. Furthermore, to better understand BNC's performance compared to other systems, we compiled electrochemical performance data recently reported in the literature at similar C-rates, presented in Figure and Table . Through comparison of specific capacities, capacity decay per cycle and the areal sulfur loading, BNC as an electrolyte additive ranked second in specific discharge capacity and second in capacity retention (capacity decay per cycle) with a relatively high areal sulfur loading (4 mg/cm 2 ), demonstrating the exceptional electrochemical performance. These findings underscore its promising potential for application in Li-S systems.
