a Schematic diagram of a flexible capacitor containing active material, current collector, and electrolyte. b Electrode–electrolyte interface bonding diagram before (upper panel) and after (lower panel) heat treatment. c Scanning electron microscope of the interface between electrode and electrolyte in the capacitor before (upper panel) and after (lower panel) heat treatment. Scale bar, 20 μm. d Optical image of the interface between electrode and electrolyte in the flexible capacitor before and after heat treatment. e Curves of peeling force per width of the PAANa-ST6 sheet and carbon cloth sheet. f Nyquist plots of the supercapacitors with different state electrolytes. g Cyclic voltammetry curves of the PAANa-ST6-based supercapacitor at different bending angles. h Galvanostatic charge–discharge curves of the PAANa-ST6-based supercapacitor after different bending cycles.
