In the electrodeposition process of aluminum, AlCl 4− and Al 2 Cl 7− are the main ions involved in the reaction, so the strong adsorption ability of the deposition substrate for these two ions helps the electrodeposition reaction.
Aluminum electrodeposition in this electrolyte seems to be feasible because the carrier ions in this electrolyte contain AlCl 4− and Al 2 Cl 7−, and the locally high concentration solvation environment inhibits the water activity.
In summary, the surface evolution of Al electrode in Al batteries was systematically studied. According to the in situ optical observation, the morphological features of the Al electrode induced by the electrochemical corrosion were responsible for the evolution on the electrode surface.
Aluminum-ion batteries (AIBs) are a promising candidate for large-scale energy storage due to the merits of high specific capacity, low cost, light weight, good safety, and natural abundance of aluminum. However, the commercialization of AIBs is confronted with a big challenge of electrolytes.
Since the reaction on the surface of the aluminum anode is mainly the plating and stripping of aluminum, its electrochemical properties are influenced by the atomic structure of the anode surface. Aluminum has a face-centered cubic structure, with significant changes in each crystal plane.
When the aluminum is immersed in acidic aqueous electrolytes (e.g., pH 2–4), the oxidation of aluminum leads to water electrolysis to make the local environment more alkaline ( eqs 2 and 3 ), which results in the rise of pH. Then, the aluminum passivates due to the formation of Al (OH) 3 on the aluminum surface ( eq 4) (11,13,14)
