A Potential distribution during charge and B during discharge at 50% SOC and 50 mA/cm2. C The potential loss due to ion transport in the NaCl/H2O at different current densities. In all cases Qaq = 0.02 mL/s and Qorg = 0.002 mL/s. The positions of Cl2-CCl4, NaCl/H2O, porous RuO2-TiO2@C positive electrode, and NaTi2(PO4)3 negative electrode are labeled in the legend. Fig. 5 Charge and discharge behavior of CFB and comparisons of the performance matrices to redox flow batteries reported in the past 10 years. A Cell voltage profiles during constant-current cycling and B cycle performance of CFB at 20 mA/cm2, Qaq = 0.02 mL/s and Qorg = 0.002 mL/s, and the charge capacity was set to be 600 mAh. The amount of CCl4 is 6.0 mL, the size of the porous RuO2-TiO2@C electrode is 1.0 mm-thick and 2.0 cm2 area. C The comparison of performance matrices among CFB, organic redox flow battery (anthraquinones as the anode material and ferricyanide as cathode material, ref. S24), all-vanadium redox flow battery (refs. S28, 29), Zn-Bromine redox flow battery (ref. S33), and semi-solid redox flow battery (Li as the anode and LiFePO4 as cathode material ref. S34) (see details in Table S5). expanding the material and chemistry space of the redox flow technologies. Methods Material synthesis. The activated carbon with RuO2/TiO2 particles was prepared by dissolving 0.69 mmol RuCl3 and 1.622 mmol C16H36O4Ti in 100 mL iso- propanol, then adding 2.0 g activated carbon into the solution. The mixture was stirred for 2 hours, and then the isopropanol was evaporated at 90 °C. Finally, the products were annealed at 500 °C for 1 hour under ambient conditions. The carbon-coated NaTi2(PO4)3 was synthesized from 0.002475 mol Na2CO3, 0.01485 mol NH4H2PO4, and 0.0099 mol TiO2 in 100 mL of a 2.0 wt% poly-vinyl- alcohol (PVA) aqueous solution. The mixture was stirred at 80 °C until the water evaporated and white solids formed. The white solids were placed in a porcelain boat and heated at 900 °C for 10 hours with an increasing rate of 5 °C/min under an N2 flow in a tube furnace. To improve the cycling stability and electronic conductivity, thermal vapor deposition (TVD) was employed to prepare carbon- coated NaTi2(PO4)3 after calcination. The as-prepared powder was transferred into a reaction tube to make a fluid-bed layer for the reaction at 700 °C for 2 hours where a toluene vapor was carried by N2 through the reaction tube at a flow rate of 6 NATURE COMMUNICATIONS | (2022)13:1281 | https://doi.org/10.1038/s41467-022-28880-x | www.nature.com/naturecommunicationsPDF Image | High-energy and low-cost membrane-free CFB
