Abstract

L'invention porte sur un procédé de préparation d'un matériau actif de cathode comprenant un cristal mixte. Le procédé comprend les étapes suivantes consistant à : (1) se procurer une première substance cristalline contenant un ou plusieurs éléments ayant des formules générales LixM'y(XO4)z, LiM'XO5, LiM'XO6 et LiM'X2O7; (2) se procurer une seconde substance cristalline contenant un ou plusieurs éléments ayant une formule générale AaMbNcOd; et fritter les deux substances cristallines pour former le cristal mixte. En outre, l'invention porte sur un procédé de préparation d'une batterie secondaire au lithium. Selon le matériau actif de cathode préparé par le procédé, la propriété électrique est supérieure, ce qui améliore la durée et les performances d'une batterie secondaire au lithium.
