Compared with Figure 11 a, the diameters of the small semicircles in Figure 11 b–d show a decreasing trend with the increase of the applied strain because the strain causes cracks in the Fe-C layer, as shown in Figure 5 , and allows more electrolyte to arrive at the interface between the Fe-C layer and Gr-NW, resulting a reduced resistance.
