Abstract:
(EN) Disclosed is a positive electrode active material for lithium ion secondary batteries, which contains lithium complex oxide particles that are composed of a layered compound having a hexagonal crystal structure containing nickel, manganese and cobalt. The positive electrode active material for lithium ion secondary batteries has the maximum peak for the range of 2θ = 44-45˚ within the range of 2θ = 44.4-45˚ in the powder X-ray diffraction pattern as obtained by the measurement at 25˚C using a Cu-Kα ray. Also disclosed is a lithium ion secondary battery which comprises: a positive electrode that contains a positive electrode active material capable of absorbing and desorbing lithium ions; a negative electrode that contains a negative electrode active material capable of absorbing and desorbing lithium ions; a separator and a nonaqueous electrolyte solution. The lithium ion secondary battery is characterized in that the positive electrode active material is composed of the above-described positive electrode active material for lithium ion secondary batteries.
(FR) La présente invention se rapporte à un matériau actif d'électrode positive pour des batteries secondaires au lithium ion. Le matériau actif selon l'invention contient des particules d'oxyde complexe de lithium qui sont constituées d'un composé multicouche ayant une structure de cristal hexagonal contenant du nickel, du manganèse et du cobalt. Le matériau actif d'électrode positive pour des batteries secondaires au lithium ion présente un pic maximum pour la plage de 2θ = 44 à 45˚ à l'intérieur de la plage de 2θ = 44,4 à 45˚ dans le modèle de diffraction des poudres aux rayons X tel qu'obtenu par la mesure à 25 ˚C au moyen d'un rayon Cu-Kα. La présente invention se rapporte également à une batterie secondaire lithium ion qui comprend : une électrode positive contenant un matériau actif d'électrode positive qui est apte à absorber et à désorber des ions de lithium ; une électrode négative contenant un matériau actif d'électrode négative qui est apte à absorber et à désorber des ions de lithium ; un séparateur ; et une solution d'électrolyte non aqueux. La batterie secondaire lithium ion est caractérisée en ce que le matériau actif d'électrode positive se compose du matériau actif d'électrode positive pour des batteries secondaires au lithium ion décrit dans ce qui précède.
