Abstract:
(EN) Negative electrode active material particles 10 comprise base particles 13 having: a silicate phase 11 containing Li2O, SiO2, at least one oxide selected from M1 2O3, M2O2, M3 2O5, and M4O3(where M1, M2, M3, and M4 are elements other than alkali metals, alkali earth metals, and Si), and a discretionary component MO (where M is an alkali earth metal); and silicon particles 12 dispersed in the silicate phase 11. The element contents for the elements contained in the silicate phase 11 are: 3-33 mol% of Li; 40-78 mol% of S; and 1-40 mol% of M1, M2, M3, and M4. If MO is contained, the M content in the silicate phase is 1-10 mol%.
(FR) L'invention concerne un matériau actif d'électrode négative dont les particules (10) comprennent des particules de base (13) ayant : une phase de silicate (11) contenant du Li2O, SiO2, au moins un oxyde choisi parmi M1 2O3, M2O2, M3 2O5 et M4O3 (où M1, M2, M3 et M4 sont des éléments autres que des métaux alcalins, des métaux alcalino-terreux et du Si), et un composant discrétionnaire MO (où M est un métal alcalino-terreux) ; et des particules de silicium (12) dispersées dans la phase silicate (11). Les teneurs en éléments pour les éléments contenus dans la phase de silicate (11) sont : de 3 à 33 % en moles de Li ; de 40 à 78 % en moles de S ; et de 1 à 40 % en moles de M1, M2, M3 et M4. Si du MO est contenu, la teneur en M dans la phase silicate est de 1-10 % en moles.
(JA) 負極活物質粒子10は、LiOと、SiOと、M、M、M及びM(M、M、M,Mはアルカリ金属、アルカリ土類金属、Si以外の元素)のうちの少なくともいずれか1つから選択される酸化物と、任意要素のMO(Mはアルカリ土類金属)と、を含むシリケート相11と、シリケート相11中に分散したシリコン粒子12と、を有する母粒子13を備え、シリケート相11における各元素の含有量は、Liが3~33モル%であり、Sが40~78モル%であり、M、M、M及びMは1~40モル%であり、前記MOを含む場合、前記シリケート相におけるMの含有量は、1~10モル%である。
