  • Patent number: 7820317
    Abstract: The invention relates to a method for treating all types of lithium anode cells and batteries by means of a hydrometallurgical process at room temperature. The treatment method enables cells and batteries comprising a metallic lithium-based anode or an anode containing lithium incorporated in an anodic insertion compound to be treated under safe conditions, thus enabling the metallic casings, electrode contacts, cathode metal oxides and lithium salts to be separated and recovered.

  • Publication number: 20100062673
    Abstract: The present invention relates to a method for integral recycling of cathode ray tubes characterized in that it enables glasses which compose said cathode ray tubes and luminophores deposited on an internal surface of screens to be recycled by associating the following steps: opening said cathode ray tubes by means of a laser source; dry cleaning by means of surface treatment agents; and recycling the luminophores by acid-base means in the presence of fluorides. Well-chosen association of a particular opening method, of a dry surface treatment and a hydrometallurgical treatment step of the luminophores powders results in a method enabling both protection of environment and of a workstation and a high material valorization rate.
