METHOD FOR PRODUCING NEGATIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, AND LITHIUM SECONDARY BATTERY INCLUDING SAME
Presented is a method for producing a negative electrode active material which has a high discharge capacity, a high charge-discharge efficiency, and excellent high-output characteristics, and which experiences only a small volume change during charging/discharging. A method for producing a negative electrode active material for a lithium secondary battery according to an embodiment of the present invention comprises: a step for producing primary particles by crushing a carbon raw material containing 4 to 10 wt% of volatile components; a step for producing secondary particles by mixing the primary particles with a binder; and a step for producing a graphite material by graphitizing the secondary particles.
L'invention concerne un procédé de production d'un matériau actif d'électrode négative qui présente une capacité de décharge élevée, un rendement de charge-décharge élevé et d'excellentes caractéristiques de sortie élevée, et qui subit uniquement un faible changement de volume pendant la charge/décharge. Selon un mode de réalisation de la présente invention, un procédé de production d'un matériau actif d'électrode négative pour une batterie secondaire au lithium comprend : une étape de production de particules primaires par broyage d'une matière première de carbone contenant de 4 à 10 % en poids de composants volatils ; une étape de production de particules secondaires par mélange des particules primaires à un liant ; et une étape de production d'un matériau de graphite par graphitisation des particules secondaires.
