Figure 5. (A) Initial galvanostatic discharge/charge profiles (50 mA g-1); (B) Cycling stability (50 mA g-1); (C) Rate capability and (D) Cycling stability of N-C and Fe-N-C-2 (500 mA g-1); (E) CV curves of the Fe-N-C-2 at multiple sweep rates; (F and G) respectively corresponding to quantitative analysis of capacitive contribution of the Fe-N-C-2 at 1.0 mV s-1 and capacitive contribution of the N-C and Fe-N-C-2 at multiple sweep rates. CV: Cyclic voltammetry.
