Figure 6. Electrochemical performance of lawsone-based AORFBs[48]. (A) Structure of lawsone-K; (B) CV curves of 0.01 M lawsone (red curve) and 0.02 M TEMPO (yellow curve). Scan rate: 50 mV s-1; (C) OCVs versus SOCs; (D) Voltage profiles concerning battery capacity. Current density: 5-15 mA hcm-2; (E) Constant-current cycling and (F) battery efficiencies. Current density: 10 mA cm-2; (G) Long cycle performance of 0.1 M lawsone. Current density: 15 mA cm-2. Reproduced with permission[48]. Copyright 2019, Elsevier.
