The published cathode data was analyzed in terms of C-rate and cycle number. C-rate values are either provided in the literature or calculated based on the highest reported discharge capacity and mass loading of active materials, respectively. The listed references include VO2(B),[11]CuHCF,[12]ZnHCF,[13]V6O13,[14]Mo6S8,[15]MoS2,[16]I2,[17]Zn0.25V2O5·nH2O,[1]NaV3O8·1.5H2O,[18]β-MnO2,[19]PANI,[20]Na0.14TS2,[21]α-MnO2,[1]PANI-MnO2,[22]VOPO4,[23]Co3O4,[24]BT-PTO-COF,[25]V2O3.[26]The best performance in this work is also presented.
