Figure 6. (A) CV curves of the ZVNW-CC electrode at different scan rates. (B) b value of the redox peak in the CV curve. (C) GITT curves during discharge and charge. (D) Corresponding Zn²⁺ diffusion coefficient during the 2nd cycle of charge-discharge. (E) Nyquist plots of ZVNW-CC and ZVNW electrodes before cycling in the frequency range of 0.01 Hz to 100 kHz. (F) The Ragone plot comparison of Zn/ZVNW-CC battery with other cathode materials for AZIBs.
