要約
(EN)
This negative electrode material for lithium ion secondary batteries is obtained by doping silicon oxide (SiOz, wherein 1.5 > z > 0.5) particles with nitrogen. A peak ascribed to a compound of Si and N is not seen in an X-ray diffraction measurement of this negative electrode material for lithium ion secondary batteries.
(FR)
La présente invention concerne un matériau d'électrode négative pour batteries secondaires au lithium-ion qui est obtenu par dopage à l'azote de particules d'oxyde de silicium (SiOz, où 1,5 > z > 0,5). Un pic assigné à un composé de Si et de N n'est pas observé lors d'une mesure par diffraction des rayons X de ce matériau d'électrode négative pour batteries secondaires au lithium-ion.
(JA)
 リチウムイオン二次電池用負極材料は、酸化ケイ素SiOz(但し1.5>z>0.5)粒子に窒素をドープしてなるリチウムイオン二次電池用負極材料であって、X線回折測定においてSiとNの化合物のピークが観察されない。
