摘要： Current collector for electrochemical devices comprising a metal support in contact with an electrolyte containing a bistriflimide anion, hereafter named as TFSI - , characterized in that said metal support comprises an electro-active surface which is functionalized with linear or branched fluorinated carbon chains, such as a perfluoroalkyl chains, in the form of a molecular layer which improves the corrosion resistance of said functionalized surface compared to a non-functionalized surface. The invention also relates to the use of said current collector in a storage energy device, such as a lithium-ion, sodium-ion, aluminum-ion, calcium-ion or magnesium-ion battery, in a supercapacitor, in a photo-battery, or in an electro-chromic device, and to the process of functionalizing the active surface of the current collector.
