a Schematic image of the textile-based SC energy storage module consisting of current collectors, CNT-PEDOT:PSS-based electrodes and PVA-based solid gel electrolyte. Each module is composed of five SC units connected in series. b The photo image of the printed SC module. Scale bar, 5 mm. c The charge storage mechanism of the hybrid SC unit based on both the double-layer capacitance and pseudocapacitance. d GCD with currents of 25, 50, 100, 250, and 500 μA of a SC unit from 0 V to 1 V. e CV with scan rates of 5, 10, 25, 50, 100 mV s−1 from 0 V and 1 V of a SC unit. f GCD of the energy storage modules with different configurations, with (i) two storage modules in series; (ii) one storage module; and (iii) two storage modules in parallel. g Images of the inward and outward bending of the SC module. Scale bar, 1 cm. h 5 μA GCD of the SC module before and after 1000 cycles of 180º bending deformation. i The areal capacitance and coulombic efficiency of a SC unit in 1000 charge-discharge cycles.
