Abstract:
(EN) Provided are a positive-electrode active material capable of exerting a high potential and capable of suppressing the elution of metal elements, and a lithium ion secondary battery having excellent capacity and high-temperature service life. The present invention has: a composite oxide containing Li (lithium) and a transition metal including at least Mn (manganese); and a surface oxide that is an oxide having a metal element with a valence of two or more. The composite oxide is fluorinated in a surface layer section (B) thereof, and is not fluorinated in a center section (C) thereof. The surface oxide (A) is present on the surface of the composite oxide, and is fluorinated.
(FR) La présente invention concerne une substance active d'électrode positive capable d'appliquer un potentiel élevé et capable de supprimer l'élution d'éléments métalliques, et une batterie secondaire lithium-ion ayant d'excellentes capacité et durée de vie à haute température. La présente invention comporte : un oxyde composite contenant Li (lithium) et un métal de transition comprenant au moins Mn (manganèse); et un oxyde de surface qui est un oxyde ayant un élément métallique avec une valence de deux ou plus. L'oxyde composite est fluoré dans une partie de couche de surface (B), et n'est pas fluoré dans une partie centrale (C). L'oxyde de surface (A) est présent sur la surface de l'oxyde composite, et est fluoré.
(JA)  高電位を発現でき、金属元素の溶出を抑制できる正極活物質と、容量と高温寿命に優れたリチウムイオン二次電池を提供する。Li(リチウム)と少なくともMn(マンガン)を含む遷移金属との複合酸化物と、2価以上の金属元素を有する酸化物である表面酸化物とを有する。複合酸化物は、表層部(B)がフッ素化しており、中央部(C)がフッ素化していない。表面酸化物(A)は、複合酸化物の表面に存在し、フッ素化している。
