Figure 6

(a, b) Comparison of the CV and GCD profiles for NCS aerogel and NCS/CN composite aerogels (1CN, 3CN, and 5CN) at a scan rate of 5 mV·s^-1, and a current density 10 mA·cm^-2. (c) CV curves of 3CN composite aerogels at various scan rates. (d) Cathodic and anodic peak current values at different scan rates. (e, f) GCD curves of 3CN composite aerogels at different current densities. (g) Specific capacitances and (h) EIS spectra of NCS aerogel and NCS/CN aerogels (1CN, 3CN, and 5CN) and (i) cyclic stability of NCS aerogel and 3CN composite aerogels (inset shows first and last 6 GCD cycles).
