Abstract:
(EN) According to the present invention, a positive electrode is provided with: a positive electrode collector which contains aluminum; a positive electrode mixture layer which contains a positive electrode active material that is configured of a lithium transition metal oxide; and an intermediate layer which is arranged between the positive electrode collector and the positive electrode mixture layer. The intermediate layer contains inorganic compound particles, a conductive material and a binder; the circularity is from 5% to 75% (inclusive); the void fraction of the intermediate layer is from 30% to 69% (inclusive); and the average circularity of the inorganic compound particles is from 5% to 75% (inclusive).
(FR) Selon la présente invention, une électrode positive est pourvue : d'un collecteur d'électrode positive qui contient de l'aluminium; d’une couche mixte d'électrode positive qui contient un matériau actif d'électrode positive qui est constitué d'un oxyde de métal de transition de lithium; et d’une couche intermédiaire qui est disposée entre le collecteur d'électrode positive et la couche mixte d'électrode positive. La couche intermédiaire contient des particules de composé inorganique, un matériau conducteur et un liant; la circularité vaut de 5 % à 75 % ; la porosité de la couche intermédiaire vaut de 30 % à 69 % ; et la circularité moyenne des particules de composé inorganique vaut de 5 % à 75 %.
(JA) 正極は、アルミニウムを含む正極集電体と、リチウム遷移金属酸化物で構成される正極活物質を含む正極合材層と、正極集電体及び正極合材層の間に設けた中間層とを備え、中間層は、無機化合物粒子、導電材及び結着材を含み、真円度が5%以上75%以下であり、かつ、中間層の空隙率が30%以上69%以下であり、無機化合物粒子の真円度の平均値が5%以上75%以下である。
