Abstract: front page image
(EN) The present invention provides a negative electrode active material for a lithium secondary battery. The negative electrode active material is a silicon-containing alloy composed of chemical formula 1 of SixMyNz, where 30≤x≤60, 1≤y≤20, 30≤z≤60, x+y+z = 100; x, y, and z each represent atomic%; and M and N each represent a transition metal, and is characterized by having a porous structure which can be obtained by rapidly solidifying the alloy in a molten state and is composed of solid active silicon fine particles and an inactive intermetallic compound which is distributed around the silicon fine particles and may have a solid region and an amorphous region, wherein some portions of the solid region distributed around the fine particles are removed.
(FR) La présente invention concerne un matériau actif d'électrode négative pour une batterie rechargeable au lithium. Le matériau actif d'électrode négative est un alliage contenant du silicium composé de la formule chimique (1) de SixMyNz, où 30 ≤ x ≤ 60, 1 ≤ y ≤ 20, 30 ≤ z ≤ 60, x + y + z = 100 ; x, y et z représentent chacun un % atomique ; et M et N représentent chacun un métal de transition, et est caractérisé en ce qu'il présente une structure poreuse qui peut être obtenue par solidification rapide de l'alliage dans un état fondu et est composé de fines particules de silicium actives solides et d'un composé intermétallique inactif qui est réparti autour des fines particules de silicium et peut comporter une région solide et une région amorphe, certaines parties de la région solide réparties autour des fines particules étant enlevées.
(KO) 본 발명은 실리콘(Si)를 포함하는 합금으로서, 상기 합금은 하기 화학식 1로 이루어지되, [화학식 1] SixMyNz 상기 식에서 30≤x≤60, 1≤y≤20, 30≤z≤60, x+y+z = 100이며, x, y, z는 각각 원자%, M,N은 전이금속임 상기 합금을 용융상태에서 급냉응고시켜 얻을 수 있는, 고상의 활성 실리콘(Si) 미세입자 및 상기 실리콘(Si) 미세입자 주위에 분포하는 고체영역과 비정질영역이 혼재할 수 있는 비활성 금속간화합물에서, 상기 미세입자 주위에 분포하는 고체영역 중 일부를 제거한 다공성 특징이 있는 리튬이차전지용 음극활물질을 제공한다.
