Title (EN) NEGATIVE ACTIVE MATERIAL FOR RECHARGEABLE LITHIUM BATTERY, METHOD OF PREPARING THE SAME, AND RECHARGEABLE LITHIUM BATTERY INCLUDING THE SAME
(FR) MATÉRIAU ACTIF NÉGATIF POUR BATTERIE AU LITHIUM RECHARGEABLE, PROCÉDÉ DE PRÉPARATION, ET BATTERIE AU LITHIUM RECHARGEABLE LE COMPRENANT
Abstract: front page image
(EN)Disclosed are a method of preparing a negative active material for a rechargeable lithium battery that includes: preparing a powder including a material being capable of doping and dedoping lithium; coating the powder including the material being capable of doping and dedoping lithium with metal particles; etching the powder including the material being capable of doping and dedoping lithium and coated with the metal particles; and coating the etched powder including the material being capable of doping and dedoping lithium with carbon, a negative active material for a rechargeable lithium battery prepared in this method, and a rechargeable lithium battery including the negative active material.
(FR)L'invention concerne un procédé de préparation d'un matériau actif négatif pour une batterie au lithium rechargeable qui consiste à : préparer une poudre comprenant un matériau capable de doper et de dédoper du lithium ; recouvrir la poudre comprenant le matériau capable de doper et de dédoper du lithium avec des particules métalliques ; attaquer la poudre comprenant le matériau capable de doper et de dédoper du lithium et couverte de particules métalliques ; et recouvrir la poudre attaquée comprenant le matériau capable de doper et de dédoper du lithium avec du carbone. L'invention concerne également le matériau actif négatif pour une batterie au lithium rechargeable préparé selon ce procédé, ainsi qu'une batterie au lithium rechargeable comprenant le matériau actif négatif.
