A great loss on capacitance was found in the Rec-4NW and CoCuNW based supercapacitors with capacitance values lower than 50% respect their initial values. A flakes film was found on Rec-6NW positive electrodes surface after its cycling (Fig. 6 e). The same flakes film was found in all the produced nanowires electrodes after galvanostatic cycling.
