Title: ELECTROCHEMICAL DEVICES, WITH CURRENT COLLECTOR HAVING AN INCREASED RESISTANCE TO CORROSION
Abstract:
Electrochemical device or photo-electrochemical device comprising an electrolyte containing a bistriflimide anion, hereafter named as TFSI-, at least two electrodes, each of these electrodes being in contact with a current collector comprising a metal support characterized in that at least one electrode has a current collector the metal support of which comprises an electro-active surface which is functionalized with linear or branched fluorinated carbon chains, such as perfluoroalkyl chains, in the form of a molecular layer which improves the corrosion resistance of said functionalized surface compared to a non- functionalized surface, wherein not impairing the passage of electrons between said electrode and its current collector, the functionalized surface being at the interface between said electrode and its current collector.
