Fig. 4 — a Zinc deposition curves at 0.1 mA cm⁻² on bare Zn anodes and Zn@CuNW anodes. b XRD pattern (inset: enlarged zone) of CuNW/membrane after depositing 1 mAh cm⁻² zinc on the Zn@CuNW electrodes. c Binding energies between the zinc atom and different substrates of Zn plate and Cu nanowires. d Calculation model of zinc absorbed on (0001) facet of Zn plates. e Bird view and f atomic model of the single-crystalline Cu nanowire. Stable adsorption sites for one zinc atom on various facets and edges of the Cu nanowires: g (111) facet, h (110) facet, (i) (100) facet, j edge 1 and k edge 2. The Lyons blue and brownish red balls are Zn and Cu atoms, respectively
