Electrochemical performance of flexible solid-state supercapacitors based on (MXene/TAEA)n electrodes. a Schematic illustration of a solid-state supercapacitor based on (MXene/TAEA)n on PET sheet as electrodes and PVA/H2SO4 as the electrolyte. b CV curves at a scan rate of 2 mV s−1, and c charge-discharge profiles at a current density of 0.02 mA cm−2 for (MXene/TAEA)n with bilayer number n. d CV curves at different scan rates and e charge-discharge profiles at different current densities of (MXene/TAEA)20. f Areal capacitances, and g volumetric capacitances of (MXene/TAEA)n with different bilayer numbers, n, at different scan rates. h Ragone plot of (MXene/TAEA)n solid-state supercapacitors based on total active electrode volume. i CV curves of (MXene/TAEA)20 solid-state supercapacitors measured for different degrees of bending, and the inset shows a photograph of the solid-state supercapacitor with symmetrical electrodes on PET sheet
