<p>Lithium ion cells in which the cathode contains a particulate insertion material and a binder are cut open in a dry, inert atmosphere (10). The cell components are treated with a first organic solvent (12) to dissolve the electrolyte, so that this can be reused. They are then treated with a second organic solvent (16) to dissolve the binder, and the particulate material separated (18) from the solution of binder. The insertion material is then reduced (22) so that it does not contain intercalated lithium. The reduction process may be performed electrolytically.</p> |
