Effect of hydrogen carbonate and chloride on zinc corrosion investigated by a scanning flow cell system

Challenges, mitigation strategies and perspectives in development of zinc-electrode materials and fabrication for rechargeable zinc–air batteries

“…Besides, to investigate the influence of electrolytes with different compositions or concentrations on zinc corrosion, intensive investigations have been carried out. For example, Laska et al 69 investigated the influence of changing the electrolyte composition over time by dynamic electrolyte exchange and found that a compact precipitation layer was formed in hydrogen carbonate-and chloride-containing electrolytes, which then hindered the surface corrosion of the zinc-electrode.

A novel coupling of electrochemical impedance spectroscopy with atomic emission spectroelectrochemistry: Application to the open circuit dissolution of zinc

“…In earlier work we used this technique coupled simultaneously with a quartz crystal microbalance to give simultaneously zinc oxidation, dissolution, and interfacial mass changes with excellent agreement between the three measurements [19]. More recently Klemm et al [20,21] and Laska et al [22] have used a micro flow cell with downstream UV-visible detection to separate zinc oxidation and dissolution.…”

Highly Reversible Zn Anode Enabled by Controllable Formation of Nucleation Sites for Zn‐Based Batteries

“…Therefore, during the Zn reduction process, the HER would take place and change the concentration of electrolyte, which accelerate the further Zn anode corrosion, leading to the low energy efficiency and probably safety issue through increasing the pressure of the whole battery. [25,26] Thus, to obtain a Zn anode with less corrosion and higher performance, the critical efforts are to achieve uniform nucleation sites for Zn 2+ , forming an even current distribution on the surface of Zn anode by promoting the fast transportation of Zn 2+ and suppressing the H 2 evolution for increasing the efficiency and safety. Regarding the formation of nonconductive ZnO densification (also called "Zn passivation"), it can hinder the effective reaction of metal…”
