Gel filling method dependent mechanical stability. a, b The gel infilling-dependent microcracks (or lack of microcracks) in ~150 μm in thick MWCNT electrodes rolled-up over a glass tube with a radius of ~0.5 mm fabricated by the two methods. Electrochemical performance of c and d once rolled-up FSSC devices and e after repeated bending. In e the capacitance retention with the bending number is confirmed by GCD at a current density of 0.15 mA after every 500 bends at bending radius of curvature of 5.7 mm. Scale bar for a and b is 500 μm
