Figure 5. Electrochemical performance of CoP/Co2P/C-0.8. (A) CV curves with the scan rate of 0.1 mV s-1; (B) charge/discharge curves with the current density of 100 mA g-1; (C) dQ/dV curves; (D) cycling performance of different nanofibers with the current density of 100 mA g-1; (E) charge/discharge curves with different current densities; (F) rate capabilities and (G) cycling performances under 1,000 mA g-1 of different nanofibers. CoP/Co2P/C: CoP/Co2P nanoparticles onto N, P co-doped carbon substrate; CV: cyclic voltammetry; dQ/dV: differential capacity.
