Abstract
(EN) Provided are a carbonate salt compound and a positive electrode active material, which enable the production of a lithium ion secondary battery having an excellent cycle property. A method for producing a carbonate salt compound, which comprises mixing a sulfate salt (A) comprising a sulfate salt of Mn and a sulfate salt of Ni or comprising a sulfate salt of Mn, a sulfate salt of Ni and a sulfate salt of Co with a carbonate salt (B) comprising sodium carbonate and/or potassium carbonate in an aqueous solution to precipitate a carbonate salt compound having a Mn content of 33.3 to 65 mol%, a Ni content of 17.5 to 50 mol% and a Co content of 0 to 33.3 mol% all relative to the total amount of Ni, Co and Mn in the average composition of the whole body of the carbonate salt compound, wherein the ratio of the amount of Mn relative to the total amount of Ni, Co and Mn in the sulfate salt (A) at the time of the initiation of the mixing is adjusted to a value larger than 65 mol%. A method for producing a positive electrode active material, which comprises mixing a carbonate salt compound produced by the aforementioned method with lithium carbonate and then burning the resultant mixture at 500 to 1000°C.
(FR) L'invention porte sur un composé de type sel de type carbonate et sur une matière active d'électrode positive, qui permettent la production d'une batterie secondaire au lithium-ion ayant une excellente propriété de cycle. L'invention porte également sur un procédé pour la production d'un composé de type sel de type carbonate, qui comprend le mélange d'un sel de type sulfate (A) comprenant un sel de type sulfate de Mn et un sel de type sulfate de Ni ou comprenant un sel de type sulfate de Mn, un sel de type sulfate de Ni et un sel de type sulfate de Co, avec un sel de type carbonate (B) comprenant du carbonate de sodium et/ou du carbonate de potassium dans une solution aqueuse pour faire précipiter un composé de type sel de type carbonate ayant une teneur en Mn de 33,3 à 65 % en mole, une teneur en Ni de 17,5 à 50 % en mole et une teneur en Co de 0 à 33,3 % en mole, le tout par rapport à la quantité totale de Ni, Co et Mn dans la composition moyenne du corps entier du composé de type sel de type carbonate, le rapport de la quantité de Mn sur la quantité totale de Ni, Co et Mn dans le sel de type sulfate (A) au moment du début du mélange étant réglé à une valeur supérieure à 65 % en mole. L'invention porte également sur un procédé pour la production d'une matière active d'électrode positive, qui comprend le mélange d'un composé de type sel de type carbonate produit par le procédé susmentionné avec du carbonate de lithium et ensuite la combustion du mélange ainsi obtenu à une température de 500 à 1000°C.
