Description:
Due to the intercalation of both cations and anions in this new type of battery, the voltage can reach values above 5 V. This can lead to the corrosion of the aluminum current collector if the electrolyte containing fluorinated anions is used. However, the advantages of ionic liquid over organic solvent based solutions overbalance and there is no useful option to replace them. Therefore it is necessary to protect the aluminum current collector with an electronically conductive, defect free and stable coating. Several coating methods and material compositions were tested and the performance of the coatings are investigated in long term cell tests with cyclic voltammetry.
