摘　　要：金属铝作为世界上应用最广泛的轻金属,产量大,需求高。随着我国碳达峰、碳中和目标的持续推进,铝电解节能降耗迫在眉睫,而降低电解温度是实现铝电解节能的重要途径。文中论述了低温铝电解方法的发展历程、优缺点、发展前景;优化传统铝电解质体系,实现低温铝电解、以铝盐为电解质的传统低温铝电解、离子液体低温制备金属铝及其他方法制备金属铝。发展低温铝电解技术、降低能耗对我国实现碳达峰、碳中和的目标具有重大意义。Metal aluminum features are widely used and have large output as well.With the “double-carbon” goal(carbon emission peak and carbon neutrality) enjoyed by Chinese government to continue to promote,aluminum electrolytic energy savings are imminent,and reducing the temperature of aluminum electrolysis is an important way to achieve energy savings.Therefore,this paper discusses the development history,advantages and disadvantages and prospects of low-temperature aluminum electrolysis methods,including optimizing the traditional aluminum electrolyte system to achieve low-temperature aluminum electrolysis,conventional low-temperature aluminum electrolysis with aluminum salts as electrolytes,low-temperature preparation of metal aluminum by ionic liquid and other methods.Developing low-temperature aluminum electrolysis technology to reduce energy consumption is of great significance for China to achieve the goals of carbon emission peak and carbon neutralization.
