Figure 7. Electrochemical kinetic behavior analysis of CoP/Co₂P/C-0.8. (A) CV curve as the scan rate increases from 0.1 to 1.0 mV s^-1; (B)b values; (C) pseudo-capacitive contribution at 0.2 mV s^-1; (D) the values of pseudo-capacitive contribution at different scan rates; (E) EIS curves and (F) Li⁺ diffusion coefficients of different nanofibers. CoP/Co₂P/C: CoP/Co₂P nanoparticles onto N, P co-doped carbon substrate; EIS: electrochemical impedance spectroscopy.
