(FR) PROCÉDÉ DE PRÉPARATION DE PARTICULES DE CATHODE AU LITHIUM-ION ET MATÉRIAU ACTIF DE CATHODE FORMÉ À PARTIR DE CES DERNIÈRES
요약서:
(EN) A method of preparing cathode particles using a co-precipitation reaction in a reactor is disclosed. A feed stream (a) containing metal cations is fed into the reactor, and a feed stream (b) containing anions is fed into the reactor, wherein a ratio of the metal cations in the feed stream (a) is continuously changed from A1 at time t1 to A2 at time t2. The feed stream (a) and the feed stream (b) are contacted in the reactor to form precipitated precursor particles, and at least one transition metal component in the particle has a non-linear continuous concentration gradient profile over at least a portion along a thickness direction of the particle.
(FR) L'invention concerne un procédé de préparation de particules de cathode à l'aide d'une réaction de co-précipitation dans un réacteur. Un flux d'alimentation (a) contenant des cations métalliques est introduit dans le réacteur, et un flux d'alimentation (b) contenant des anions est introduit dans le réacteur, un taux des cations métalliques dans le flux d'alimentation (a) variant en continu de A1 à un instant t1 à A2 à un instant t2. Le flux d'alimentation (a) et le flux d'alimentation (b) sont mis en contact dans le réacteur pour former des particules de précurseur précipitées, et au moins un constituant métal de transition dans la particule a un profil de gradient de concentration continu non linéaire sur au moins une partie située dans le sens de l'épaisseur de la particule.
