Abstract:
(EN) This positive electrode active material for lithium secondary batteries contains: a lithium composite metal compound that is composed of secondary particles, each of which is formed of aggregated primary particles; and a lithium-containing tungsten oxide. The lithium-containing tungsten oxide is present at least in spaces among the primary particles; and the surface area of pores within the pore diameter range of from 10 nm to 200 nm (inclusive) in the pore distribution of this positive electrode active material for lithium secondary batteries as determined by a mercury intrusion method is from 0.4 m2/g to 3.0 m2/g (inclusive).
(FR) L'invention concerne un matériau actif d'électrode positive pour batteries secondaires au lithium contenant : un composé métallique composite de lithium qui est composé de particules secondaires, chacune d'entre elles étant formée de particules primaires agrégées; et un oxyde de tungstène contenant du lithium. L'oxyde de tungstène contenant du lithium est présent au moins dans des espaces entre les particules primaires; et la surface des pores à l'intérieur de la plage de diamètres de pores allant de 10 nm à 200 nm (inclus) dans la distribution de pores de ce matériau actif d'électrode positive pour des batteries secondaires au lithium telle que déterminée par un procédé d'intrusion de mercure est de 0,4 m2/g à 3,0 m2/g (inclus).
(JA) このリチウム二次電池用正極活物質は、一次粒子が凝集して形成された二次粒子からなるリチウム複合金属化合物と、リチウム含有タングステン酸化物とを含むリチウム二次電池用正極活物質であって、少なくとも前記一次粒子の粒子間隙に前記リチウム含有タングステン酸化物が存在し、水銀圧入法によって測定されたリチウム二次電池用正極活物質の細孔分布において、細孔径が10nm以上200nm以下の範囲の細孔表面積が0.4m/g以上3.0m/g以下である。
