An Electrochemical Investigation of the 1‐Methyl‐3‐Ethylimidazolium Bromide Aluminum Bromide Molten Salt System

The electrochemical behavior of the room temperature molten salt made by combining 1‐methyl‐3‐ethylimidazolium bromide and aluminum bromide was studied. It was found that the bromide system behaved, for the most part, analogously to the chloride counterpart. Bromide solvated in a room temperature molten salt is electrochemically similar to bromide in other nonaqueous solvent systems. The diffusion coefficients and the heterogeneous rate constants were determined for the bromide and tribromide species in the molten salt.
