“…Due to high HER overpotential, these elements could reduce Zn corrosion. In more recent studies, Bi is the most widely used alloying element which is also reported to be beneficial to controlling dendrite growth and shape change of Zn electrodes (Kim et al, 2015;Jo et al, 2017;Chotipanich et al, 2018;Park et al, 2018).…”

Zn is an important negative electrode material in our battery industry and nextgeneration Zn based batteries are prospective to compete with lithium-ion batteries on cost and energy density. Corrosion is a severe challenge facing Zn electrodes, which can decrease the capacity, cyclability, and shelf life of batteries. More attention should be paid to Zn electrode corrosion in developing rechargeable and high energy density Zn batteries. In this mini review, the fundamental electrochemical behavior and corrosion of Zn electrodes in aqueous environment are retrospected. Then main strategies in recent studies to mitigate Zn electrode corrosion including electrolyte additives usage, electrode composition design and electrode morphology modification are reviewed.

“…Non-uniform dissolution/deposition of the active Zn species leads to Zn dendrite formation and excessive ZnO precipitation on the surface of the Zn anode, causing low Zn utilization, capacity loss and even short circuit in the alkaline electrolyte during repeated charging-discharging processes [10][11][12][13]. Numerous efforts have been devoted to addressing the dendrite formation and surface passivation issues of Zn anodes, such as the construction of three-dimensional (3D) Zn architectures [14][15][16][17][18], alloying Zn with heavy metals [19][20][21], and coating Zn anode with a protective layer [22][23][24]. Despite these efforts, realizing uniform dissolution/deposition of Zn for advanced electrochemical set-ups, and probing the correlation between structure engineering and performance optimization remain challenging.…”

Zn-air batteries are promising energy storage and conversion systems to replace the conventional lithiumbased ones. However, their applications have been greatly hindered by the formation of Zn dendrites and ZnO passivation layer on the Zn anodes. Herein, we report the fabrication of an artificial protective layer comprised of N-doped threedimensional hollow porous multi-nanochannel carbon fiber with well-dispersed TiO 2 nanoparticles (HMCNF). The incorporated TiO 2 nanoparticles and N dopants improve the ion flux distribution and promote the surface adsorption, facilitating the interfacial pseudocapacitive behaviors during Zn deposition. The hierarchical architecture also induces homogenous electric field distribution at the anode/electrolyte interface. Accordingly, the deposition behavior of Zn is regulated, giving rise to enhanced utilization and rechargeability of Zn. When integrated in alkaline Zn-air batteries, the HMCNF-coated Zn anodes exhibit improved electrochemical performances relative to those with the bare Zn anodes, demonstrating a versatile strategy to boost energy storage of metal anodes through optimizing surface adsorption properties.

“…The polar group is adsorbed on the Zn surface while the non‐polar group escape from the Zn surface to form a shielding layer that constrains Zn corrosion. Inhibitors like Indium, tetrabutyl ammonium bromide and lead oxide (PbO), 4 tetra alkyl ammonium hydroxide cellulose, 5 hydrocalumite, 6 bismuth oxide, 7 activated carbon, 8 polyethyleneimine, 9 carbopol 940, 10 and so on have been studied.…”

Summary Zinc (Zn) particles in alkaline electrolyte of a Zn‐air battery (ZAB) are unstable and prone to corrosion. Zinc oxide (ZnO) generated on the surface of Zn particles affects the electrochemical reactions and reduces the battery efficiency. Thus, inhibiting the self‐corrosion rate of Zn particles has become acritical issue for the development of these batteries. In this study, a research endeavor has been attempted by employing three types and concentrations of organic inhibitors in ZABs to constrain Zn anode corrosion. Significant analyses like polarization curve, constant current discharge, AC impedance, and dendrite growth are executed for in‐depth understanding of the influences of these inhibitors. The experimental results reveal that the inhibiting efficiency of 10 wt% Sodium dodecyl benzene sulfonate surpassed polyethylene glycol 600 (PEG 600) and polysorbate 20 (Tween 20), with a maximum current density of 476.20 mA/cm2 and voltage output of 1.4 V along with discharge capacitance of 10.31 Ah for 2 hours and 8 minutes. Zn anode surface analysis exposes significant dendrite growth and elemental Zn required for passivation suppression. Nevertheless, the results are also justified by Nyquist and Bode plots. Thus, the selected inhibitor will proficiently guarantee the enhanced performance and stability of the ZABs obtained and provide enormous opportunities for its applications.
