Patent number: 8236453Abstract: The invention provides a new route for the synthesis of carbon-coated powders having the olivine or NASICON structure, which form promising classes of active products for the manufacture of rechargeable lithium batteries. Carbon-coating of the powder particles is necessary to achieve good performances because of the rather poor electronic conductivity of said structures. For the preparation of coated LiFePO4, sources of Li, Fe and phosphate are dissolved in an aqueous solution together with a polycarboxylic acid and a polyhydric alcohol. Upon water evaporation, polyesterification occurs while a mixed precipitate is formed containing Li, Fe and phosphate. The resin-encapsulated mixture is then heat treated at 700° C. in a reducing atmosphere. This results in the production of a fine powder consisting of an olivine LiFePO4, phase, coated with conductive carbon.Type: GrantFiled: March 8, 2011Date of Patent: August 7, 2012Assignees: Umicore, Le Centre National de la Recherche ScientifiqueInventors: Albane Audemer, Calin Wurm, Mathieu Morcrette, Sylvain Gwizdala, Christian Masquelier
