Abstract[English]
Provided are a cathode active material and a method of preparing the same. The method of preparing a cathode active material includes a mixture preparation step of mixing a precursor with a lithium compound, an ion-generating step of generating lithium ions from the mixture so that the lithium ions permeate into the precursor, and a calcination step of calcining the precursor into which the lithium ions have been permeated.[French]
L'invention concerne un matériau actif de cathode et son procédé de préparation. Le procédé de préparation d'un matériau actif de cathode comprend une étape de préparation de mélange consistant à mélanger un précurseur avec un composé de lithium, une étape de génération d'ions consistant à générer des ions lithium à partir du mélange de sorte que les ions lithium pénètrent dans le précurseur, et une étape de calcination consistant à calciner le précurseur dans lequel les ions lithium ont pénétré.
