Fig. 5. Electrochemical performance of aqueous Zn-iodine flow batteries.

Fig. 5.

(A) Capacity versus cycle number at different rates for Zn-iodine low batteries with blank CF and EG@CF+ AC@CF. (B) Average discharge voltage and power density at different current densities were obtained using EG@CF+ AC@CF electrodes. Cycling performance of EG@CF+ AC@CF electrodes at (C) 80 mA/cm2, 5.3 mA·hour/cm2 and (D) 100 mA/cm2, 25 mA·hour/cm2. (E) The voltage-time curve of (D). (F) The voltage-capacity curve of (D).
