Electrochemical Survey of Selected Cations and Electrode Materials in Dialkylimidazolium Chloroaluminate Melts

摘要

Room temperature chloroaluminate melts of 7 dialkylimidazolium chlorides were prepared and studied using cyclic voltammetry in basic (excess organic) and acidic (excess AlCl3) regions. 1-methyl-3-ethyl imidazolium chloride was selected for further electrochemical studies. Twenty-one electrode materials were studied for stability in the melts. Initial studies were performed to identify and characterize the redox and metal deposition behaviors of 25 cations (primarily chloride salts of transition metal ions). (Author)
