Abstract
(EN)
The present invention relates to a method for manufacturing a cathode active material for a lithium secondary battery from a recovered cathode active material and a cathode active material for a lithium secondary battery manufactured thereby. In the manufacturing method for a cathode active material for a lithium secondary battery from a recovered cathode active material according to the present invention, a desired composition for the cathode active material can be prepared by adding a metal raw material to the recovered cathode active material as necessary and prepared into pellet forms which are then fired to adjust the diameters thereof within a predetermined range. The lithium secondary battery comprising the recovered cathode active material of the present invention can have improved packing density properties and charge-discharge characteristics.

La présente invention concerne un procédé de fabrication d'un matériau actif de cathode pour une batterie secondaire au lithium à partir d'un matériau actif de cathode récupéré et un matériau actif de cathode pour une batterie secondaire au lithium ainsi fabriqué. Dans le procédé de fabrication d'un matériau actif de cathode pour une batterie secondaire au lithium à partir d'un matériau actif de cathode récupéré selon la présente invention, une composition souhaitée pour le matériau actif de cathode peut être préparée par ajout d'une matière première métallique au matériau actif de cathode récupéré si nécessaire et préparée sous forme de pastilles qui sont ensuite cuites pour ajuster leurs diamètres dans une plage prédéfinie. La batterie secondaire au lithium comprenant le matériau actif de cathode récupéré de la présente invention peut présenter des propriétés de densité de tassement améliorées et des caractéristiques de charge-décharge améliorées.
