Abstract

L'invention concerne un procédé de fabrication d'un matériau actif de cathode comprenant la fourniture d'un premier mélange constitué d'une composition de métaux mixtes et d'acide phosphorique ou d'une composition de métaux mixtes et d'eau. La composition de métaux mixtes comprend du nickel, du cobalt, du manganèse, ou une combinaison de ceux-ci. Un sel de fer, de manganèse, de cobalt, ou une combinaison de ceux-ci, est ajouté pour ajuster la stœchiométrie de la composition de métaux mixtes. La composition de métaux mixtes ajustée stœchiométriquement dans l'eau peut être mise en contact avec un composé contenant du phosphore. Le phosphate des métaux mixtes ajusté stœchiométriquement est en outre mis en contact avec un composé contenant du lithium pour fournir le matériau actif de cathode ayant au moins une phase à structure d'olivine.
