Title (EN) POSITIVE ELECTRODE ACTIVE SUBSTANCE FOR ALL SOLID-STATE LITHIUM SECONDARY BATTERY
(FR) MATIÈRE ACTIVE D'ÉLECTRODE POSITIVE POUR BATTERIE SECONDAIRE AU LITHIUM TOUT SOLIDE
(JA) 全固体型リチウム二次電池用正極活物質
Abstract:
(EN) In this positive electrode active substance for an all solid-state lithium secondary battery, the surface of the core particles, configured from lithium metal composite oxides having a layer structure containing at least Li, an element M (M includes a combination of one or more elements selected from the group consisting of at least Ni, Co, Mn and Al) and O, is covered with an amorphous compound containing Li, A (A is a combination of one or more elements selected from the group consisting of Ti, Zr, Ta, Nb, Zn, W and Al) and O, and the primary particles of the core particles are polycrystalline; this positive electrode active substance for an all solid-state lithium secondary battery is characterized in that D50 is 0.5-11 μm, the value ((|mode diameter - D50|/mode diameter)×100) is 0-25%, the value ((|mode diameter - D10|/mode diameter)×100) is 20-58%, and the average primary particle diameter/D50 is 0.01-0.99.
(FR) L'invention concerne une matière active d'électrode positive dans laquelle la surface de particules noyau principal qui sont constituées d'un oxyde complexe de métal de lithium ayant une structure en couches contenant Li, un élément M (M contient une combinaison d'éléments chimiques d'une ou plusieurs sortes choisies dans un groupe constitué au moins de Ni, Co, Mn et Al.) et O, est revêtu par un composé non cristallin contenant Li, A (A consiste en une combinaison d'éléments chimiques d'une ou plusieurs sortes choisies dans un groupe constitué de Ti, Zr, Ta, Nb, Zn, W et Al) et O. Cette matière active d'électrode positive pour batterie secondaire au lithium tout solide est caractéristique en ce qu'une valeur D50 est comprise entre 0,5μm et 11μm, une valeur ((|diamètre modal D50|/diamètre modal )×100) est comprise entre 0 et 25%, une valeur ((|diamètre modal-D10|/diamètre modal)×100) est comprise entre 20 et 58%, et le rapport diamètre moyen de particule primaire / D50 est compris entre 0,01 et 0,99.
(JA) Li、M元素(Mは、少なくともNi、Co、Mn及びAlからなる群から選択される一種または二種以上の元素の組合せを含む。)及びOを含む層状構造を持つリチウム金属複合酸化物からなる本コア粒子の表面が、Li、A(AはTi、Zr、Ta、Nb、Zn、W及びAlからなる群から選択される一種又は二種以上の元素の組合せである。)及びOを含む非晶質化合物で被覆されている正極活物質であって、D50が0.5μm~11μmであり、((|モード径-D50|/モード径)×100)の値が0~25%であり、((|モード径-D10|/モード径)×100)の値が20~58%であり、かつ、平均一次粒子径/D50が0.01~0.99であることを特徴とする全固体型リチウム二次電池用正極活物質。
