Figure 4. (A) The CV curves of SS-1 under different scan rates. (B) the charge and discharge curves SS-1 at different current densities. (C) the specific capacitance of SS-0.1 and SS-1 at different current densities. (D) cycling stability of SS-0.1 and SS-1 after 2,000 and 10,000 cycles at a current density of 100 mA g-1. (E) energy density and power density of SS-0.1 and SS-1 at different current densities. (F) relationship between energy density and power density of SS-0.1 and SS-1 (Ragone plot).
