Figure 5.

Digital photographs of the PANI/CNT/EVA electrode: (a) mass loading, (b) twisted into a spiral shape or tied into a knot, stretched, and released. (c) CV curves of the PANI/CNT/EVA electrode under different bending angles. (d) CV and (e) discharge curves of solid-state symmetric supercapacitors at different scan rates and current densities. (f) Digital photographs of the assembled flexible solid-state symmetric supercapacitors (3 in series) lighting LEDs. (g) Ragone plots of the areal energy density and power density, and the structure of flexible solid-state symmetric supercapacitors.
