Rechargeable aluminum batteries (RABs) present considerable potential for large-scale energy storage, particularly within power stations. Nonetheless, their operational lifespan and commercialization are hindered by issues like Al anode dendrite formation and electrolyte corrosion. To address the aforementioned issues, a stabilizer has been proposed to enhance the electrolyte/anode interface. Experimental and computational simulation results indicate that the surface tension of the SDBS alkyl chain facilitates its preferential adsorption onto the electrode surface, thereby establishing a protective layer that mitigates the corrosion of the chloroaluminate ionic liquid (ILs). Additionally, the suitable electronegativity of the phenyl-SO
