The introduction of an aluminum salt into the IL electrolyte, such as a mixture of (EMImCl–AlCl 3), transforms the role of the Al anode, shifting it from a mere alloying electroactive material to a more complex participant. In this context, aluminum-based anions like Al 2 Cl 7− or analogous species are exchanged with the electrolyte.
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.
To investigate the ability of the electrolyte to electrochemically dissolve or deposit aluminum, symmetrical coin cells with aluminum electrodes were assembled and chronoamperometry measurements were performed at room temperature by applying a bias voltage of 0.6 V using a BioLogic Battery tester BCS-805 (see Figure 7 ).
