“…These observations are correlated with the fact that the cathodic exchange-current density values are less than those of the anodic counter parts. It can be concluded that the overall kinetics of corrosion of both Zn and Zn-0.5Ni alloy in 7 M KOH solution are under cathodic control [23]. The corresponding value for the transfer coefficient (˛) lies between 0.46 and 0.57, indicating that the processes correspond to a simple discharge mechanism for hydrogen evolution reaction.…”

“…The increase of potential over a certain period of discharge is due to the discharge products deposition on the electrode surface, which hinders the discharge process. The consequent steady potential values indicate an established dynamic equilibrium between the formation and desorption of discharge products [50]. The fluctuation of potentials becomes apparent with the increase of the discharge current by comparing Figure 9a-c within the steady discharge period.…”

Abstract:The Mg-6%Al-3%Zn and Mg-6%Al-3%Zn-(1%, 1.5%, 2%)In alloys were prepared by melting and casting. Their microstructures were investigated via metallographic and energy-dispersive X-ray spectroscopy (EDS) analysis. Moreover, hydrogen evolution and electrochemical tests were carried out in 3.5 wt% NaCl solution aiming at identifying their corrosion mechanisms and discharge behaviors. The results suggested that indium exerts an improvement on both the corrosion rate and the discharge activity of Mg-Al-Zn alloy via the effects of grain refining, β-Mg 17 Al 12 precipitation, dissolving-reprecipitation, and self-peeling. The Mg-6%Al-3%Zn-1.5%In alloy with the highest corrosion rate at free corrosion potential did not perform desirable discharge activity indicating that the barrier effect caused by the β-Mg 17 Al 12 phase would have been enhanced under the conditions of anodic polarization. The Mg-6%Al-3%Zn-1.0%In alloy with a relative low corrosion rate and a high discharge activity is a promising anode material for both cathodic protection and chemical power source applications.

“…The potential of the Zn electrode reaction is below the potential for hydrogen evolution, which causes the electrolyte to be thermodynamically unstable [58]. However, H 2 evolution on the Zn surface can be kinetically suppressed with dopants, such as Hg, In, or Bi [19,[59][60][61].…”

A Review of Model-Based Design Tools for Metal-Air Batteries

Abstract:The advent of large-scale renewable energy generation and electric mobility is driving a growing need for new electrochemical energy storage systems. Metal-air batteries, particularly zinc-air, are a promising technology that could help address this need. While experimental research is essential, it can also be expensive and time consuming. The utilization of well-developed theory-based models can improve researchers' understanding of complex electrochemical systems, guide development, and more efficiently utilize experimental resources. In this paper, we review the current state of metal-air batteries and the modeling methods that can be implemented to advance their development. Microscopic and macroscopic modeling methods are discussed with a focus on continuum modeling derived from non-equilibrium thermodynamics. An applied example of zinc-air battery engineering is presented.
