Abstract:
(EN) Provided is a secondary battery electrode active material exhibiting favorable high rate discharge characteristics and having a large discharge capacity by means of limiting the amount of impurities in the electrode active material, which has a lithium-nickel-manganese complex oxide having a spinel structure as the primary component. Further provided is a secondary battery provided with the active material. The secondary battery electrode active material has a lithium-nickel-manganese complex oxide having a spinel structure as the primary component. The ratio of the main peak strength in the (200) plane of impurities having a halite structure with respect to the main peak strength in the (111) plane resulting from x-ray diffraction of the lithium-nickel-manganese complex oxide having a spinel structure is no greater than 3.0%, and the half band width of the diffraction line in the (111) plane of the lithium-nickel-manganese complex having a spinel structure is no greater than 0.135°.
(FR) La présente invention concerne un matériau actif d'électrode de batterie secondaire qui possède des caractéristiques favorables de taux de décharge élevé et qui possède une haute capacité de décharge en limitant la quantité d'impuretés dans le matériau actif d'électrode, qui comporte un oxyde complexe de lithium-nickel-manganèse à structure spinelle en tant que composant principal. La présente invention concerne également une batterie secondaire pourvue du matériau actif. Le matériau actif d'électrode de batterie secondaire comporte un oxyde complexe de lithium-nickel-manganèse à structure spinelle en tant que composant principal. Le rapport de la résistance maximum principale dans le plan (200) d'impuretés possédant une structure halite par rapport à la résistance maximum principale dans le plan (111) résultant d'une diffraction de rayons X de l'oxyde complexe de lithium-nickel-manganèse à structure spinelle n'est pas supérieur à 3,0 %, et la demi-largeur de bande de la ligne de diffraction dans le plan (111) de l'oxyde complexe de lithium-nickel-manganèse à structure spinelle n'est pas supérieure à 0,135°.
(JA)  スピネル型構造を有するリチウムニッケルマンガン複合酸化物を主成分とする電極活物質中の不純物の量を限定することにより、放電容量が大きく、良好な高率放電特性を示す二次電池用電極活物質およびそれを備えた二次電池を提供する。二次電池用電極活物質は、スピネル型構造を有するリチウムニッケルマンガン複合酸化物を主成分とする二次電池用電極活物質であって、スピネル型構造を有するリチウムニッケルマンガン複合酸化物のX線回折による(111)面のメインピーク強度に対する、岩塩型構造を有する不純物の(200)面のメインピーク強度の比率が3.0%以下であり、かつ、スピネル型構造を有するリチウムニッケルマンガン複合酸化物の(111)面における回折線の半値幅が0.135°以下である。
