A composite material having utility as a cathode material for a lithium ion battery includes a first component which is a metal phosphate and a second component which is a metal nitride, a metal oxynitride, or a mixture of the two. The second component is coated on, or dispersed through the bulk of, the first component. The metal phosphate may be a lithiated metal phosphate and may be based upon one or more transition metals. Also disclosed is a method for preparing the material as well as electrodes fabricated from the material and lithium ion cells which include such electrodes.
L'invention a trait à un matériau composite utile en tant que matériau de cathode pour une batterie lithium-ion. Ledit matériau comprend un premier élément, qui est un phosphate métallique, et un second élément, qui est un nitrure métallique, un oxynitrure métallique ou un mélange de ces derniers. Le second élément est déposé sur le premier élément ou est dispersé dans la masse de celui-ci. Le phosphate métallique peut être un phosphate métallique lithié et peut être formé à base d'un ou plusieurs métaux de transition. L'invention concerne également un procédé de préparation du matériau, ainsi que des électrodes produites à partir de ce dernier, et des batteries lithium-ion intégrant de telles électrodes.
