Title (EN) POSITIVE ELECTRODE ACTIVE MATERIAL FOR SODIUM ION SECONDARY BATTERY
(FR) MATÉRIAU ACTIF D'ÉLECTRODE POSITIVE POUR BATTERIE SECONDAIRE AU SODIUM-ION
(JA) ナトリウムイオン二次電池用正極活物質
Abstract:
(EN) Provided is a positive electrode active material for a Ni-based sodium ion secondary battery having an excellent discharge capacity. The positive electrode active material for a sodium ion secondary battery is characterized by being composed of crystals represented by a general formula of Nax(Ni1-aMa)yP2Oz (M is at least one transition metal element selected from the group consisting of Fe, Cr, Mn, and Co, and the relationship of 0.6≤x≤4, 0.3≤y≤2.7, 0≤a≤0.9, 6≤z<7.5 is satisfied).
(FR) L'invention concerne un matériau actif d'électrode positive pour une batterie secondaire au sodium-ion à base de Ni ayant une excellente capacité de décharge. Le matériau actif d'électrode positive pour une batterie secondaire au sodium-ion est caractérisé en ce qu'il est composé de cristaux représentés par une formule générale Nax(Ni1-aMa)yP2Oz ( M est au moins un élément de métal de transition choisi dans le groupe constitué de Fe, Cr, Mn, et Co, et les relations 0,6≤x≤4, 0,3≤y≤2,7, 0≤a≤0,9, 6≤z<7,5 sont satisfaites).
(JA) 放電容量に優れたNi系のナトリウムイオン二次電電池用正極活物質を提供する。 一般式Na(Ni1-a(MはFe、Cr、Mn及びCoからなる群より選ばれた少なくとも一種の遷移金属元素であり、0.6≦x≦4、0.3≦y≦2.7、0≦a≦0.9、6≦z<7.5を満たす)で表される結晶からなることを特徴とするナトリウムイオン二次電池用正極活物質。
