TABLE 2.
Factors affecting the performance of ionic liquid-based electrolytic aluminum ([Emim]Cl/AlCl3).
| Factor | Performance | |
|---|---|---|
| Electrode materials | Aluminum Cathode | Kinetically controlled electrodeposition of aluminum on the aluminum cathode |
| Tungsten Cathode | Transient nucleation and diffusion-controlled growth | |
| P90 Li–Al Alloy | A uniform and dense aluminum layer obtained at an electrodeposition rate of 10 μm/h | |
| Nd–Fe–B Alloy | A dense and continuous layer obtained on the surface | |
| Operational parameters | Current Density | Enhanced adhesion of the aluminum layer to the substrate with increasing current density |
| Electrolyte Composition | Electrolyte composition ([Emim]Cl:AlCl3 molar ratio between 1:1.4 and 1:2) would help to obtain a uniform and dense electrodeposited aluminum layer | |
| Additives | Benzene | Significantly improved quality of the electrodeposited aluminum layer |
| Nicotinic Acid | Obtained average grain size under the same operation conditions of 14.0 ± 0.3 nm | |
| Decane | Prevented the electrolyte from contacting water or air |
