Figure 2. (A) Oxygen evolution curves and (B) hydrogen evolution curves of Zn//stainless steel asymmetric cells based on the linear sweep voltammetry test at a scan rate of 0.5 mV s-1; (C) XRD patterns of Zn anode after 10 cycles in UE and BE; SEM images of Zn anode after 50 cycles in (D) UE and (E) BE; (F) Contact angles of UE and BE on the surface of Zn anode. XRD: X-ray diffraction; UE: urea electrolyte; BE: blank electrolyte; SEM: scanning electron microscope.
