Abstract: front page image
(EN)The present invention relates to a negative electrode active material for secondary batteries, capable of absorbing and desorbing ions, and to a secondary battery including the negative electrode active material, the active material consisting of: a core of a crystalline carbonaceous substance; and a composite coating layer that includes at least one substance selected from the group consisting of low crystalline carbon and amorphous carbon, and a metal and/or non-metal capable of absorbing and desorbing ions. Here, the composite coating layer is configured such that a matrix is made of one component selected from said at least one substance selected from the group consisting of low crystalline carbon and amorphous carbon, and the metal and/or non-metal capable of absorbing and desorbing ions, wherein a filler made of the other component is further included in the matrix.
(FR)La présente invention concerne un matériau actif d'électrode négative pour batteries secondaires capable d'absorber et de désorber les ions et une batterie secondaire contenant le matériau actif d'électrode négative, le matériau actif se composant des éléments suivants : un noyau d'une substance carbonée cristalline ; et une couche de revêtement composite qui contient au moins une substance sélectionnée parmi le groupe composé du carbone faiblement cristallin et du carbone amorphe, et un métal et/ou un non-métal capables d'absorber et de désorber les ions. La couche de revêtement composite est ici configurée de telle sorte qu'une matrice est constituées d'un composant sélectionné parmi ladite ou lesdites substances sélectionnée parmi le groupe composé du carbone faiblement cristallin et du carbone amorphe, et le métal et/ou le non-métal capables d'absorber et de désorber les ions, une charge de remplissage réalisée dans l'autre composant étant en outre incluse dans la matrice.
(KO)본 발명은, 이온을 흡장 및 방출할 수 있는 이차전지용 음극 활물질로서, 결정성 카본계 물질의 코어(core)와, 저결정성 카본 및 비정질 카본으로 이루어진 군에서 선택되는 하나 이상의 물질과 이온의 흡장 및 방출이 가능한 금속 및/또는 비금속을 포함하는 복합체 코팅층(composite coating layer)으로 이루어져 있으며, 상기 복합체 코팅은 저결정성 카본 및 비정질 카본으로 이루어진 군에서 선택되는 하나 이상의 물질, 및 이온의 흡장 및 방출이 가능한 금속 및/또는 비금속 중에서 선택된 하나의 성분으로 이루어진 매트릭스(matrix)에 나머지 성분으로 이루어진 필러(filler)가 포함되어 있는 구조로 이루어진 음극 활물질과, 이러한 음극 활물질을 포함하는 것으로 구성된 이차전지를 제공한다.
