The present invention relates to a structure comprising successively: .cndot. a layer of a metal L1, possibly a fluorinated primary L2 which is a mixture comprising by weight 1 to 100% of at least one polymer fluorine modified for 0 to 99% of fluorinated polymer, and a layer of a fluoropolymer L3, .cndot. such as if the L2 primer layer is absent then the polymer fluorinated L3 is a mixture comprising by weight 1 to 100% of at least one fluoropolymer modified for 0 to 99% of polymer respectively fluorine, .cndot. said modified fluoropolymer being selected from: ~ the fluoropolymers grafted by an unsaturated monomer, the grafting being carried out in the absence of oxygen by irradiation of unsaturated monomer and previously fluorinated polymer mixed in the molten state, ~ fluorinated polymers irradiated in the presence of oxygen (also designated by fluorinated oxidized polymers). According to a particular form, the structure of the invention is an electrode of a lithium-ion battery in which the metal L1 is the collector and the fluorinated polymer L3, strongly charged with carbon and / or oxides, is the electroactive layer. |
