英文摘要： The electrolytic aluminum industry is the largest electrochemical industry. The electrodeposition of aluminum in the ionic liquid has more advantages than the traditional electrolytic aluminum technology. However, the technology of the electrodepostion of aluminum in the ionic liquid exist some problems, such as the loose and easily off of the aluminum layer and it is difficult to obtain the thickness and density electrodeposited aluminum layer in the ionic liquid. According to the magnetic effect on the electron transfer and the polarity electric particles transport and distribution, the magnetic field was introduced during the electrodeposition of aluminum in the 1-Ethyl-3-methylimidazolium chloride ionic liquid. In order to know the magnetic effect and its mechanism on the behavior of the interface during the electrodeposition of aluminum in the ionic liquid, the magnetic effect and its mechanism on the electric double layer , the process on the working electrode and the behavior of the electrodeposition of aluminum on the interface should been investigated. The investigation should provide the theory support to synthesis the thickness and density aluminum electrodeposited layer in the ionic liquid. In this way, to enrich the interface theories about molten salt electrochemistry, it should supply a basis and technological lead to the effective, economic energy and friendly to the environment of the aluminum metallurgy.
