Ionic Liquids Electrolyte for Use in Al-ion Batteries
碩士 === 國立中央大學 === 材料科學與工程研究所 === 102 === In this study, we have investigated the electrochemical behavior of Aluminium in various ionic liquids (ILs). These ILs are EMICl-AlCl3 (1-ethyl-3-methylimidazolium chloride/aluminum chloride), Bu3MeNCl -AlCl3 (Tributyl-methylamine chloride/aluminum chloride)...

| Summary: | 碩士 === 國立中央大學 === 材料科學與工程研究所 === 102 === In this study, we have investigated the electrochemical behavior of Aluminium in various ionic liquids (ILs). These ILs are EMICl-AlCl3 (1-ethyl-3-methylimidazolium chloride/aluminum chloride), Bu3MeNCl -AlCl3 (Tributyl-methylamine chloride/aluminum chloride),BMP-DCA (1-butyl-1-methylpyrrolidinium /dicyanmide) with AlCl3 additive and the upper layer solution of EMI-TFSI (1-ethyl-3-methylimidazolium/ bis(trifluoromethanesulfonyl)imide) with AlCl3 additive. We have known about Aluminium showed near 95 % retention efficiency after 2000 life cycles in the EMICl-AlCl3 ionic liquid. It is the best prefoimance in the four kinds of ionic liquids.
In the following research, we choosed vanadium-oxide as the anode made by anodic deposition method and hydrothermal method. The result showed vanadium-oxide could not make Al2Cl7- ion insertion and deinsertion, which is the main species of Aluminium in EMICl-AlCl3 ionic liquid. The result means that the crstallography and categories of electrode materials have important influence on Al2Cl7- ion insertion and deinsertion.
