a Schematic representation of the NBSB employed in this study, depicting the placement of a Li metal anode within the anolyte solvent (BMP-TFSI/LiTFSI) and the dissolution of redox-active materials in the catholyte solvent FEC. b Discharge capacities of 0.1, 0.2, and 0.5 M Li||Tri-TEMPO NBSBs. c 20th, 50th, and 100th charge/discharge profiles of 0.5 M NBSB. d Coulombic efficiency, voltage efficiency, and energy efficiency of 0.5 M NBSB. e Cyclic voltammograms of 0.5 M NBSB before and after 100 charge/discharge cycles (catholyte). The measurements were conducted under an inert argon atmosphere (at 27 °C), with long-term cycling of batteries performed at a current density of 1 mA/cm². CV measurements were carried out at a scan rate of 50 mV/s.
