Additionally, rate capability assessment was conducted by incrementally increasing the C-rate from C/10 to 1C, followed by reverting to C/10, as shown in Figure . The 0.01 M BNC-containing electrolyte exhibited a discharge capacity of approximately 846.28 mAh/gsulfur and a CE of 98.2% after exposure up to 1C. This signifies a noteworthy capacity recovery compared to the baseline (732.17 mAh/gsulfur) and the 0.11 M BNC (642.07 mAh/gsulfur), indicating an enhanced stress-sustaining capacity in the optimally concentrated BNC electrolyte.
