Abstract: front page image
(EN)Disclosed is a raw material charcoal composition which is used as a raw material for a negative electrode material of lithium ion secondary batteries. This raw material charcoal composition is characterized in that when the composition is graphitized in an inert gas atmosphere at 2,800˚C, the ratio between the crystallite size Lc(002) and the lattice constant co(002) of the (002) plane as determined by x-ray diffraction analysis, namely Lc(002)/co(002), is not more than 180, and the ratio between the crystallite size La(110) and the lattice constant ao(110) of the (110) plane as determined by x-ray diffraction analysis, namely La(110)/ao(110), is not more than 1,500.
(FR)L'invention décrit une composition de charbon de matière première servant de matière première pour un matériau d'électrode négative de batteries secondaires lithium-ion. La composition de charbon de matière première est caractérisée en ce que, lorsque la composition est graphitisée dans une atmosphère de gaz inerte à 2 800 °C, le rapport entre la dimension de cristallite Lc(002) et la constante de réseau co(002) du plan (002) déterminée par analyse par diffraction des rayons X, à savoir Lc(002)/co(002), n'est pas supérieure à 180, et le rapport entre la dimension de cristallite La(110) et la constante de réseau ao(110) du plan (110) déterminée par analyse par diffraction des rayons X, à savoir La(110)/ao(110), n'est pas supérieure à 1 500.
(JA) 本発明に係る原料炭組成物は、リチウムイオン二次電池負極材料の原料となるものであって、不活性ガス雰囲気下、2800°Cの温度で黒鉛化処理されると、X線回折によって求められる002面における結晶子サイズLc(002)と格子定数co(002)の比(Lc(002)/co(002))が180以下であり且つ110面における結晶子サイズLa(110)と格子定数ao(110)の比(La(110)/ao(110))が1500以下となることを特徴とする。
