Amalgamated aluminum electrodes in acidic chloroaluminate molten salts

摘要

Aluminum was electrochemically deposited in and stripped from mercury substrates in acidic 1-methyl-3-ethylimidazolium chloride-AlCl3 molten salts. Electrodissolution occurred at 220 and 45 mA cm-2 from mercury pool and amalgamated aluminum rotating cylinder electrodes, respectively. In contrast to pure aluminum electrodes, neither of these electrodes exhibited passive behavior.
