Figure 6

Performance of the NP-10k-T3||AC ASC: (a) CVs at different scan rates and (b) the corresponding capacitance calculated from (a). (c) Galvanostatic discharge curves at different current rates and (d) the corresponding capacitance calculated from (c). (e) Long-term charge-discharge performance at a current rate of 25 mA cm-2. (f) A photograph shows an ASC powering up 16 red LEDs arranged in the pattern of “SME.” (g) Ragone plot which compares the energy density versus power density curves of the NP-10k-T3||AC asymmetric supercapacitor.
