Abstract: front page image
(EN)The present invention relates to an anode active material for a lithium secondary battery, a method for manufacturing the same, and a lithium secondary battery comprising the same. The anode active material comprises a surface-treated silicon nanoparticle, wherein the surface-treated silicon nanoparticle comprises a silicon nanoparticle and a surface treatment layer which is positioned on the surface of the silicon nanoparticle and includes crystalline SiO2, so that the anode active material, when being applied to a battery, can exhibit excellent lifespan and capacity characteristics as well as remarkably improved initial efficiency characteristics.
(FR)L'invention concerne un matériau actif d'anode pour une batterie secondaire au lithium, son procédé de fabrication, et une batterie secondaire au lithium le comprenant. Le matériau actif d'anode comprend une nanoparticule de silicium traitée en surface, la nanoparticule de silicium traitée en surface comprenant une nanoparticule de silicium et une couche de traitement de surface qui est positionnée sur la surface de la nanoparticule de silicium et comprend SiO2 cristallin, de sorte que le matériau actif d'anode, lorsqu'il est appliqué à une batterie, peut présenter d'excellentes caractéristiques de capacité et de durée de vie, ainsi que des caractéristiques de rendement initial remarquablement améliorées.
(KO)본 발명은 리튬 이차전지용 음극활물질, 이의 제조방법, 및 이를 포함하는 리튬 이차전지에 관한 것으로, 상기 음극활물질은 표면처리된 실리콘 나노입자를 포함하고, 또 상기 표면처리된 실리콘 나노입자는 실리콘 나노입자, 및 상기 실리콘 나노입자의 표면에 위치하며, 결정질 SiO2를 포함하는 표면처리층을 포함함으로써, 전지에 적용시 우수한 수명 및 용량 특성과 함께 현저히 개선된 초기 효율 특성을 나타낼 수 있다.
