Abstract

Linvention concerne un matériau de cathode, sa méthode de préparation et une batterie. Le matériau de cathode est un oxyde composite à base doxyde de nickel-lithium-cobalt comprenant un noyau et une couche de reconstruction de surface disposée à lextérieur du noyau. La couche de reconstruction de surface est une zone attaquée par dissolution du matériau de cathode avec de leau régale diluée 100 fois pendant 30 minutes, à une température ambiante maintenue à 300 °C pendant la dissolution. Le noyau est la zone restante après attaque de la couche de reconstruction de surface. Le noyau a une teneur molaire en Li de m1, tandis que la couche de reconstruction de surface a une teneur molaire en Li de m2, avec 1,3≤m2/m1≤ 4,0. Le matériau de cathode ainsi proposé améliore la stabilité de la structure cristalline tout en offrant une capacité élevée, ce qui permet daméliorer la stabilité cyclique du matériau de cathode et daugmenter sa résistance à la tension.
