Title (EN) NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
(FR) BATTERIE RECHARGEABLE À ÉLECTROLYTE NON AQUEUX
(JA) 非水電解質二次電池
Abstract:
(EN) A non-aqueous electrolyte secondary battery according to one embodiment of the present disclosure is provided with a positive electrode, a negative electrode, and a non-aqueous electrolyte, wherein the positive electrode has a positive electrode active material containing a composite oxide particle that includes Ni, Co and Li, and also includes at least one among Mn and Al, and the ratio of Ni to the total number of moles of metal elements excluding Li is 50 mol% or more. In the composite oxide particle, the ratio (A/B) of a BET specific surface area (A) to a theoretical specific surface area (B) determined by the following formula is more than 1.0 and less than 3.3. Theoretical specific surface area (B) (m2/g) = 6 / (true density (g/cm3) × volume average particle diameter (μm)).
(FR) Une batterie rechargeable à électrolyte non aqueux selon un mode de réalisation de la présente invention est pourvue d'une électrode positive, d'une électrode négative et d'un électrolyte non aqueux, l'électrode positive ayant un matériau actif d'électrode positive contenant une particule d'oxyde composite qui comprend Ni, Co et Li, et comprenant également Mn et/ou Al, et le rapport de Ni sur le nombre total de moles d'éléments métalliques à l'exclusion de Li est supérieur ou égal à 50 % en moles. Dans la particule d'oxyde composite, le rapport (A/B) d'une surface spécifique BET (A) à une surface spécifique théorique (B) déterminée par la formule suivante est supérieur à 1,0 et inférieur à 3,3. Surface spécifique théorique (B) (m2/g) = 6/ (densité réelle (g/cm3) × diamètre moyen des particules en volume (µm)).
(JA) 本開示の一態様に係る非水電解質二次電池は、正極と、負極と、非水電解質とを備え、前記正極は、Ni、Co及びLiを含み、且つMn及びAlのうち少なくともいずれか一方を含む複合酸化物粒子であって、Liを除く金属元素の総モル数に対するNiの割合が50モル%以上である複合酸化物粒子を含む正極活物質を有し、前記複合酸化物粒子は、BET比表面積(A)と下記式で求められる理論比表面積(B)の比(A/B)が、1.0超、3.3未満である。 理論比表面積(B)(m/g)=6/(真密度(g/cm)×体積平均粒径(μm))
