Abstract: front page image
(EN)This composite positive electrode active material for an all-solid-state secondary battery includes: a particulate positive electrode active material; and a sulfide-based solid electrolyte layer that covers the surface of the particulate positive electrode active material, wherein the composite positive electrode active material has an average roundness higher by 1.3 times than that of a positive electrode active material in the inner nucleus of the composite positive electrode active material.
(FR)Ce matériau actif d'électrode positive composite pour une batterie rechargeable tout solide comprend : un matériau actif d'électrode positive particulaire; et une couche d'électrolyte solide à base de sulfure qui recouvre la surface du matériau actif d'électrode positive particulaire, le matériau actif d'électrode positive composite ayant une rondeur moyenne supérieure de 1,3 fois à celle d'un matériau actif d'électrode positive dans le noyau interne du matériau actif d'électrode positive composite.
(JA)粒子状の正極活物質とその表面を被覆する硫化物系の固体電解質層とを含む全固体二次電池用の複合正極活物質であり、前記複合正極活物質が、前記複合正極活物質内核の正極活物質と比較して、1.3倍以上の平均円磨度を有する複合正極活物質。
