Title (EN) PLATE-SHAPED PARTICLES FOR POSITIVE ELECTRODE ACTIVE MATERIAL OF LITHIUM SECONDARY BATTERY
(FR) PARTICULES DE FORME PLATE POUR MATÉRIAU ACTIF D'ÉLECTRODE POSITIVE DE BATTERIE SECONDAIRE AU LITHIUM
(JA) リチウム二次電池の正極活物質用の板状粒子
Abstract: front page image
(EN)The present invention relates to plate-shaped particles for a positive electrode active material of a lithium secondary battery having a layered rock salt structure, wherein lithium entry and exit face oriented particles (primary crystal particles oriented such that the (003) face crosses the plate surface of the plate-shaped particles) are disposed in a dispersed state in an aggregation of a large number of (003) face oriented particles (primary crystal particles oriented such that the (003) face is parallel with the plate surface of the plate-shaped particles).
(FR)La présente invention concerne des particules de forme plate pour matériau actif d'électrode positive d'une batterie secondaire au lithium présentant une structure de sel gemme en couche. Des particules de lithium orientées vers la face d'entrée et de sortie (des particules cristallines primaires orientées de façon à ce que la face (003) croise la surface plate des particules de forme plate) sont disposées en ordre dispersé dans une agrégation d'un grand nombre de particules orientées vers la face (003) (des particules cristallines primaires orientées de façon à ce que la face (003) soit parallèle à la surface plate des particules de forme plate).
(JA) 本発明は、層状岩塩構造を有する、リチウム二次電池の正極活物質用の板状粒子であって、リチウム出入面配向粒子((003)面が当該板状粒子の板面と交差するように配向した一次結晶粒子)が、多数の(003)面配向粒子((003)面が当該板状粒子の板面と平行となるように配向した一次結晶粒子)の集合体内に、分散状態で配置されている。
