Fig. 2: Schematic and electrochemical performance of chlorine flow battery (CFB).
From: High-energy and low-cost membrane-free chlorine flow battery
A Schematic of the CFB, the inner diameter of the tube containing CCl4 and RuO2-TiO2@C electrode is 2.0 mm, the thickness of the RuO2-TiO2@C electrode is 1.0 mm, the distance between the working and counter electrode is 3.0 mm. The thickness of the counter electrode is 3.0 mm. The height of the cell is 2.0 cm, and the volume capacity of the cell is around 2.0 mL. The total volumes of the CCl4 reservoir and the NaCl/H2O reservoir are 6.0 mL and 2.0 mL, respectively. Qaq = 0.02 mL/s and Qorg = 0.002 mL/s. Galvanostatic charge B and discharge C profiles of the CFB at different current densities. The state of charge (SOC) of the battery is normalized to the maximum reversible capacity at 10 mA/cm2, in which 100% SOC represents charge to 600 mAh. D The voltage efficiencies of the CFB at different current densities. E The power densities of the CFB at different current densities.
