Abstract:
(EN) Provided are: a negative electrode active material which contains a silicon material and makes it possible to modify the capacity maintenance rate of a secondary battery to a suitable value; and a method for producing the negative electrode active material. A negative electrode active material characterized by containing an oxygen-containing silicon material having an oxygen content (WO %) of 16 to 27% by mass exclusive (i.e., 16 < WO < 27) and a silicon content (WSi %) of 62 to 81% by mass exclusive (i.e., 62 < WSi < 81).
(FR) L’invention concerne : un matériau actif d’électrode négative qui contient un matériau de silicium et permet de modifier le taux de maintenance de capacité d’un accumulateur à une valeur appropriée ; et un procédé de production du matériau actif d’électrode négative. Elle concerne un matériau actif d’électrode négative caractérisé en ce qu’il contient un matériau de silicium contenant de l’oxygène dont la teneur en oxygène (WO %) est comprise entre 16 et 27 % exclus en masse (c.-à-d. 16 < WO < 27) et dont la teneur en silicium (WSi %) est comprise entre 62 et 81 % exclus en masse (c.-à-d. 62 < WSi < 81).
(JA) 二次電池の容量維持率を好適化可能な、シリコン材料を含む負極活物質及びその製造方法を提供する。 酸素質量%(W%)が16<W<27であり、シリコン質量%(WSi%)が62<WSi<81である酸素含有シリコン材料を含むことを特徴とする負極活物質。
