Title (EN) NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
(FR) ACCUMULATEUR À ÉLECTROLYTE NON AQUEUX
(JA) 非水電解質二次電池
Abstract:
(EN) This nonaqueous electrolyte secondary battery is provided with a positive electrode, a negative electrode and a nonaqueous electrolyte. The nonaqueous electrolyte comprises a nonaqueous solvent that contains a fluorine-containing cyclic carbonate; the positive electrode comprises a positive electrode active material that contains composite oxide particles which contain Ni, Co and Li, while containing at least one of Mn and Al, and wherein the proportion of Ni relative to the total number of moles of the metal elements excluding Li is 50% by mole or more; and the composite oxide particles are in a non-aggregated state, while having a compressive strength of 250 MPa or more.
(FR) La présente invention concerne un accumulateur à électrolyte non aqueux qui comporte une électrode positive, une électrode négative et un électrolyte non aqueux. L’électrolyte non aqueux comprend un solvant non aqueux qui contient un carbonate cyclique contenant du fluor ; l’électrode positive comprend un matériau actif d’électrode positive qui contient des particules d’oxyde composite qui contiennent du Ni, du Co et du Li, tout en contenant au moins un élément parmi Mn et Al, et la proportion de Ni par rapport au nombre total de moles des éléments de métal à l’exclusion du Li étant supérieure ou égale à 50 % par mole ; et les particules d’oxyde composite sont dans un état non agrégé, tout en ayant une résistance à la compression supérieure ou égale à 250 MPa.
(JA) 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、前記非水電解質は、含フッ素環状カーボネートを含む非水溶媒を有し、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、非凝集状態の粒子であり、250MPa以上の圧縮強度を有する。
