Title (EN) POSITIVE ELECTRODE ACTIVE MATERIAL FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERIES, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
(FR) MATIÈRE ACTIVE D'ÉLECTRODE POSITIVE POUR BATTERIES RECHARGEABLES À ÉLECTROLYTE NON AQUEUX, ET BATTERIE RECHARGEABLE À ÉLECTROLYTE NON AQUEUX
(JA) 非水電解質二次電池用正極活物質及び非水電解質二次電池
Abstract:
(EN) This positive electrode active material for nonaqueous electrolyte secondary batteries contains secondary particles, each of which is an aggregate of primary particles that are formed of a lithium-containing transition metal oxide containing Ni and W, and a boron compound that is present within and on the surfaces of the secondary particles.
(FR) Cette matière active d'électrode positive pour batteries rechargeables à électrolyte non aqueux contient des particules secondaires, dont chacune est un agrégat de particules primaires qui sont constituées d'un oxyde métallique de transition contenant du lithium contenant Ni et W, et un composé de bore qui est présent à l'intérieur et sur les surfaces des particules secondaires.
(JA) 非水電解質二次電池用正極活物質は、Ni及びWを含むリチウム含有遷移金属酸化物の一次粒子が凝集した二次粒子と、二次粒子の内部及び表面に存在するホウ素化合物と、を含む。
