In 2020, China has already committed to peak carbon dioxide emissions before 2030 and achieves carbon neutrality before 2060. Due to the high energy consumption and carbon emission of the traditional Hall-héroult method of the aluminum electrolysis process, China strictly adheres to the production ceiling of 45 million tons of aluminum and actively develops the recycling technology of aluminum, reaching the output of the recycled aluminum up to 11.5 million tons by 2025 from 6.9 million in 2020. At present, both electrolysis and refining of aluminum are processed at high temperature. Thus, the developments of energy saving processes are required. Electrodeposition of aluminum in ionic liquids can proceed at the temperature below 100℃, which is expected to develop into a novel green technique due to its less energy consumption and no emission of carbon dioxide or other pollutants. In this review, the ionic liquids used for aluminum electrodeposition are classified according to the structure of cations, and the related research progress is reviewed respectively. In addition, the application of different anodes with aluminum as main component in electrolytic refining of aluminum in ionic liquids is also summarized. Finally, the characteristics of ionic liquid electrolyte for aluminum electrodeposition are concluded and some existing problems are pointed out.
