A Silane‐Based Electroactive Film Prepared in an Imidazolium Chloroaluminate Molten Salt

Electrochemical oxidation of in the room‐temperature molten salt results in the formation of an adherent electroactive film on the surface of solid electrodes. The film is reversibly oxidized and reduced in the molten salt and is conducting when in the oxidized state. Based on x‐ray photoelectron spectroscopy analysis, the film consists of both a silane and an imidazole component, and the charge storage properties of the film are localized on the heterocyclic rings. Ths electroactive film compares favorably to other conducting polymers currently being investigated as positive electrodes in room‐temperature molten salt batteries.
