| Abstract: |
| Two typical chloroaluminate ionic liquids, including 1-butyl-methylimidazolium chloroaluminate and 1-allyl-methylimidazolium chloroaluminate were synthesized and characterized. Systematic measurements based on electrochemistry and atomic force microscope were conducted to explore electrodeposition behavior of aluminum in ionic liquids. Experimental results show that deposition process is quasi-reversible and controlled by ion diffusion. Micro-nano aluminum can be electrodeposited by this method. Structure of cation has significant effect on shape and size of aluminum deposits. Smoother and finer aluminum crystals can be obtained in ionic liquids with lower interaction energy among cations and anions. |
