Abstract[English]
Positive electrode active material, wherein the metal has a composition M, wherein M consists of Ni in a content x, Mn in a content y, Co in a content z, and A in a content a, wherein A is at least one chemical element other than Li, Ni, Mn, Co, and O, wherein x, y, z, and a are expressed as molar contents, wherein x + y + z + a = 100%, wherein x ≥ 70.0%, wherein 0 ≤ y ≤ 30.0%, wherein 0 ≤ z ≤ 30.0 %, wherein 0 ≤ a ≤ 5.0 %, wherein an X-Ray diffractogram from Cu K-α X-ray radiation source of the positive electrode active material has a (003) peak located at 2θ = 17.0° to 20.0° and (104) peak located at 2θ = 43.0° to 46.0°, wherein the ratio (maximum intensity of the (003) peak) / (maximum intensity of the (104) peak) is at least 1.880. Further disclosed are methods of manufacturing of such a Positive electrode active material.[French]
L'invention concerne un matériau actif d'électrode positive, le métal ayant une composition M, M étant constitué de Ni dans une teneur x, Mn dans une teneur y, Co dans une teneur z, et A dans une teneur a, A étant au moins un élément chimique autre que Li, Ni, Mn, Co et O, x, y, z et a étant exprimés en tant que teneurs molaires, où x + y + z + a = 100 %, x ≥ 70,0 %, 0 ≤ y ≤ 30,0 %, 0 ≤ z ≤ 30,0 %, 0 ≤ a ≤ 5,0 %, un diffractogramme de rayons X à partir d'une source de rayonnement de rayons x Cu K-α du matériau actif d'électrode positive ayant un pic (003) situé à 2θ = 17,0° à 20,0° et un pic (104) situé à 2θ = 43,0° à 46,0°, le rapport (intensité maximale du pic (003))/ (intensité maximale du pic (104)) étant d'au moins 1,880. L'invention concerne en outre des méthodes de fabrication d'un tel matériau actif d'électrode positive.
