“…As it is well known, the nucleation overpotential refers to the difference between the sharp tip voltage and the following stable mass transfer‐controlled voltage. During the first discharging process, the lower nucleation overpotential reflects the more nucleation site of Zn 2+ and more uniform nucleation of Zn 57–59. Figure 3c compares the nucleation overpotentials of Zn plating on Ti current collector at 5 mA cm −2 with a deposited amount of 1 mAh cm −2 .…”

Aqueous Zn batteries have drawn tremendous attention for their several advantages. However, the challenges of Zn anodes such as the corrosion and ZnO densification have compromised their application in rechargeable Zn‐based batteries. In this paper, a straightforward strategy is employed to facilitate the uniform Zn stripping/plating of the Zn anode through using a ZrO2 coating layer, which contributes to the controllable nucleation sites for Zn2+ and fast Zn2+ transportation through the favorable Maxwell–Wagner polarization. As a result, the low polarization (24 mV at 0.25 mA cm−2), high Coulombic efficiency (99.36% at 20 mA cm−2), and long cycle life (over 3800 h at 0.25 mA cm−2) can be obtained for the ZrO2‐coated Zn anode. It is believed that the ZrO2 coating layer can also act as an inert physical barrier to decrease the contact of the anode and electrolyte, thus reducing both the Zn corrosion and formation of ZnO densification, and then improve the reversibility of Zn anode. The results demonstrated in this work provide an appealing strategy for the future development of rechargeable Zn‐based batteries.

“…At present, many Zn-matrix composite coatings with different reinforcements, such as Zn-TiO 2 , 1 Zn-SiO 2 , 2 Zn-CeO 2 , 3 Zn-CNT, 4 Zn-SiC, 5 Zn-graphene 6 and Zn-halloysite nanotubes 7 have been prepared by the electrodeposition process. However, the corrosion resistance of pure Zn coating is not satisfactory under severe working conditions.…”

In this work, novel zinc-graphene oxide (Zn-GO) composite coatings were successfully prepared by pulse electrodeposition in choline chloride (ChCl)/urea based deep eutectic solvent (DES). The GO sheets exhibited excellent dispersion stability in ChCl : 2urea DES without stabilizing additives and were uniformly deposited in the Zn matrix. The surface morphology and textured structure of the Zn-GO composite coatings were quite different from those of pure Zn coating, owing to the effects of GO on the electrochemical deposition behavior of Zn(II). The Zn-GO composite coatings showed higher stability and better corrosion resistance than the pure Zn coating and the corrosion resistance of Zn-GO composite coatings increased with the increase of the GO concentration.

“…The corrosion potential of the VF coatings shifts to more negative potential (-447 mV) values with increasing the duty cycle from 20 to 90 %. This potential shift in E corr may be associated with increasing the Mn content in the matrix as a more active element together with the decreasing of alumina nanoparticles at high duty cycles [33,34]. In the VD coatings, increasing the pulse frequency from 50 to 400 Hz reduces the i corr and shifts the E corr to the more positive values.…”

Composition modulated nanocomposite of NiFe-Mn-Al 2 O 3 coatings were fabricated on mild steel using single bath technique through alternative variation of duty cycle at constant frequency (VD) and repeated alteration of frequency at constant duty cycle (VF). The number of layers was 32 and thickness of each layer was 2.5 lm. The results of microstructure examination by SEM and EDS for VD coatings exhibited that Fe/Al 2 O 3 -rich layers adjacent to Mn rich ones were deposited in a frequent manner. In the case of VF coatings, alternative variation of frequency did not affect the chemical composition of matrix and only changed the content of embedded nanoparticles. The microhardness of Ni-Fe-Mn-Al 2 O 3 multilayers compared to monolithic and multilayer Ni-Fe-Al 2 O 3 of the same thickness was significantly increased because of Mn incorporation into the matrix. The corrosion resistance was found to be better for VD coating in comparison to the VF ones.
