“…Moreover, an obvious cathodic reduction peak at potential of −1.28 V can be observed. As described in the literatures [28,29], the reduction proceeds in a single step (peak at −1.28 V) associated with the reduction of Zn(II) ions to Zn(0). No additional peaks are observed before overpotential deposition of Zn, indicating that no underpotential process occurs.…”

“…It can be seen that a portion of the curve exhibits a linear relationship in the plot of log versus potential. This indicates that the mass transport is the dominant rate-limiting step [28]. In addition, the cathodic exchange current density is estimated to be ∼0.132 mA cm −2 , which is only slightly lower than those on other substrates [7].…”

The electrochemical deposition of zinc on single-crystaln-type GaN(0001) from a sulphate solution has been investigated on the basis of electrochemical techniques including cyclic voltammetry, chronoamperometry, and Tafel plot. The morphology and crystal structure of zinc deposits have been characterized by means of scanning electron microscopy, X-ray diffraction, and energy-dispersive X-ray analysis. The result has revealed that the deposition of Zn on GaN electrode commenced at a potential of −1.12 V versus Ag/AgCl. According to the Tafel plot, an exchange current density of ~0.132 mA cm−2was calculated. In addition, the current transient measurements have shown that Zn deposition process followed the instantaneous nucleation in 10 mM ZnSO4+ 0.5 M Na2SO4+ 0.5 M H3BO3(pH = 4).

“…Moreover, better corrosion resistance 30 of Zn-Ni alloys than Cd coating is associated with the loose structure of CdCl 2 ·H 2 O 31 formed on Cd coating.

Corrosion mechanism of nanocrystalline Zn–Ni alloys obtained from a new DMH-based bath as a replacement for Zn and Cd coatings

17Nanocrystalline Zn-Ni alloys were proposed from a new developed 18 5,5'-dimethylhydantoin (DMH)-based bath as replacement of Zn and Cd coatings due 19 to their excellent corrosion resistance and environmental friendly properties. However, 20 the mechanism of better corrosion performance of Zn-Ni samples compared with Zn 21 and Cd coatings was rare to be investigated. In the present study, the corrosion 22 36 impedance spectra (EIS) confirm the above facts that Zn-Ni alloys have better 37 corrosion resistance than Zn and Cd coatings, which can be used as the best 38 alternative to Zn and Cd coatings. 39

Zinc–Organic Battery with a Wide Operation‐Temperature Window from −70 to 150 °C

Aqueous zinc (Zn) batteries have been considered as promising candidates for grid‐scale energy storage. However, their cycle stability is generally limited by the structure collapse of cathode materials and dendrite formation coupled with undesired hydrogen evolution on the Zn anode. Herein we propose a zinc–organic battery with a phenanthrenequinone macrocyclic trimer (PQ‐MCT) cathode, a zinc‐foil anode, and a non‐aqueous electrolyte of a N,N‐dimethylformamide (DMF) solution containing Zn2+. The non‐aqueous nature of the system and the formation of a Zn2+–DMF complex can efficiently eliminate undesired hydrogen evolution and dendrite growth on the Zn anode, respectively. Furthermore, the organic cathode can store Zn2+ ions through a reversible coordination reaction with fast kinetics. Therefore, this battery can be cycled 20 000 times with negligible capacity fading. Surprisingly, this battery can even be operated in a wide temperature range from −70 to 150 °C.
