Zusammenfassung: | The present invention relates to an anode active material, a preparation method therefor and a lithium secondary battery comprising same, the anode active material comprising at least one metal-containing particle, wherein the ratio (r2/r1) of the radius (r1) of the anode active material to the length (r2) of the longest linear line for connecting a center point of the anode active material and a distal end of the center point of the anode active material of the metal-containing particle positioned at the furthest distance is 0.8-0.95.
La présente invention concerne un matériau actif d'anode, son procédé de préparation et une batterie secondaire au lithium le comprenant, le matériau actif d'anode comprenant au moins une particule contenant du métal, le rapport (r2/r1) du rayon (r1) du matériau actif d'anode à la longueur (r2) de la ligne linéaire la plus longue pour connecter un point central du matériau actif d'anode et une extrémité distale du point central du matériau actif d'anode de la particule contenant du métal positionnée à la distance la plus éloignée étant de 0,8 à 0,95.
