By optimizing the concentration and etching duration, the ideal etching conditions are obtained. The etched Zn foil has a 3D structure, which is conducive to inducing uniform deposition and stripping of Zn 2+, and reducing the formation of zinc dendrites.
Whether it is inorganic acid or organic acid to etch Zn foil, the etched Zn anode can exhibit better electrochemical performance than bare Zn, indicating that etching Zn foil with acid solution is universal. Furthermore, the mechanism of Zn anode etched with acid solution to improve battery cycle stability can be briefly described as follows.
Therefore, the etching process is an important part of constructing a 3D Zn anode to form a high-speed ion/electron transport dual-channel. It plays a fundamental role in achieving faster kinetics and more stable electrochemical performance of Zn anodes.
At the same time, it can also ensure the orderly electrochemical reduction of Zn to form porous structure after annealing. Therefore, the etching process is an important part of constructing a 3D Zn anode to form a high-speed ion/electron transport dual-channel.
In a sense, the essence of etching is a solid–liquid reaction based on chemical corrosion. The micromorphology and structure of Zn anodes can be controlled by adjusting the etching time, concentration and temperature with different etchants.
Reproduced from Ref. with permission from Elsevier. These studies have shown that the construction of inert metal or compound layer on the surface of the Zn anode by etching reaction can indeed increase the Zn affinity and improve the corrosion resistance. Bismuth (Bi) is also a common inert metal used for Zn anode protection.
