Abstract
(EN)
Disclosed is a method for producing a positive electrode active material for a nonaqueous electrolyte secondary battery, which comprises: a step in which an intermediate is prepared by having an oxygen permeable ceramic or a precursor thereof adhere to the surface of an oxide or hydroxide that contains nickel; a step in which the intermediate and a lithium compound are mixed together; and a step in which the thus-obtained mixture is fired in the air, thereby synthesizing a lithium nickel complex oxide. The step of having an oxygen permeable ceramic or a precursor thereof adhere includes a process of having the oxygen permeable ceramic or a precursor thereof deposit on the surface of the oxide or hydroxide, for example, in an aqueous alkaline solution.

L'invention porte sur un procédé de production d'une matière active d'électrode positive pour une batterie secondaire à électrolyte non aqueux, qui comprend : une étape dans laquelle un intermédiaire est préparé par le fait d'amener une céramique perméable à l'oxygène ou un précurseur de celle-ci à adhérer sur la surface d'un oxyde ou hydroxyde qui contient du nickel ; une étape dans laquelle l'intermédiaire et un composé du lithium sont mélangés ensemble ; et une étape dans laquelle le mélange ainsi obtenu est cuit dans de l'air, ce qui synthétise de cette manière un oxyde complexe de lithium et de nickel. L'étape consistant à amener une céramique perméable à l'oxygène ou un précurseur de celle-ci à adhérer comprend un procédé consistant à amener la céramique perméable à l'oxygène ou un précurseur de celle-ci à se déposer sur la surface de l'oxyde ou de l'hydroxyde, par exemple dans une solution aqueuse alcaline.
