Demonstration of the peeling-off process for the fabrication of electrochemical capacitors. (a) A photograph of electrochemical capacitors. (b) Cyclic voltammetry (CV) curves of capacitors on the wafer and after detachment from the wafer, that is, as free-standing films. (c) Cycle performance for capacitors on the wafer and subsequent cycle performance after detachment. (d) CV curves for the supercapacitors following each mechanical deformation. (e) Specific capacitance as a function of bending repetitions (up to 10 000). (f) Specific capacitances measured at different strains; the values were also measured after releasing the applied strain. This test was repeated five times.
