Abstract
(EN) A positive electrode material 1000 in one embodiment of the present disclosure comprises a positive electrode active material 110, a coating layer 111 that includes a first solid electrolyte and covers at least part of the surface of the positive electrode active material 110, and a second solid electrolyte 100. The first solid electrolyte contains Li, M1, and F. M1 is at least one selected from the group consisting of Ti, Al, and Zr. The second solid electrolyte 100 contains Li, M2, O, and X. M2 is at least one selected from the group consisting of Ta and Nb. X is at least one selected from the group consisting of F, Cl, Br, and I.
(FR) Un matériau d'électrode positive (1000) dans un mode de réalisation de la présente invention comprend un matériau actif d'électrode positive (110), une couche de revêtement (111) qui comprend un premier électrolyte solide et recouvre au moins une partie de la surface du matériau actif d'électrode positive (110), et un second électrolyte solide (100). Le premier électrolyte solide contient Li, M1 et F. M1 est au moins un élément choisi dans le groupe constitué par Ti, Al et Zr. Le second électrolyte solide (100) contient Li, M2, O, et X. M2 est au moins un élément choisi dans le groupe constitué par Ta et Nb. X est au moins un élément choisi dans le groupe constitué par F, Cl, Br et I.
(JA) 本開示の一態様における正極材料1000は、正極活物質110と、第1固体電解質を含み、正極活物質110の表面の少なくとも一部を被覆する被覆層111と、第2固体電解質100と、を備え、第1固体電解質は、Li、M1、およびFを含み、M1は、Ti、Al、およびZrからなる群より選択される少なくとも1種であり、第2固体電解質100は、Li、M2、O、およびXを含み、M2は、TaおよびNbからなる群より選択される少なくとも1種であり、Xは、F、Cl、BrおよびIからなる群より選択される少なくとも1種である。
