AbstractTo solve the inherent problems rooted in the traditional Hall-Heroult electrolytic process for aluminium production, it's necessary to develop low-temperature and low-energy technology. In this work, Lewis acidic 1-butyl-3-methylimidazolium chloroaluminte ionic liquids were chosen as electrolyte in the electrolysis of aluminium. Unlike previous research, glassy carbon was used as inert anode material in the study. On this basis, cyclic voltammetric and chronoamperometric measurements were performed to explore the micro-electrochemical reaction in ionic liquids. Scanning electron microscope graphs show that smooth, compact and well-adherent deposits could be obtained at 313.2 similar to 353.2 K, 5 similar to 15 mA/cm(2). The mass content of aluminium in all the products is higher than 99%. At the same time, systematical study on the release and adsorption of Cl-2 generated from inert anode was also carried out. According to experimental results, more than 96% efficiency has been achieved at -0.1 Mpa, 313.2 similar to 373.2 K and 5 similar to 25 mA/cm(2). It's expected that the present work may be useful for industrial application of ionic liquids in aluminium production.
