| description | There is provided a method for producing an electrode material for a lithium-ion secondary battery. The method comprises the following steps: (a) mixing, in an aqueous solution, components of an active substance of electrode material and a conductive carbon material, supplying the solution to a chamber, and a hydrothermal reaction is carried out in the chamber to obtain a conductive carbon material-composited material, wherein the conductive carbon material is a combination of carbon black and at least two types of fibrous carbon material, and wherein the types of fibrous carbon material are of different sizes; (b) mixing the conductive carbon material-composited material and a surface layer-forming material; an (c) burning the mixture obtained at step (b) to obtain the electrode material. Also, there is provided a lithium-ion secondary battery comprising an electrode which comprises the material according to the invention.
L'invention porte sur un procédé de fabrication d'un matériau d'électrode pour une batterie secondaire au lithium-ion. Le procédé comprend les étapes consistant à : (a) mélanger des composants d'un ingrédient de base ou d'une substance active de matériau d'électrode et une matière carbonée conductrice dans le but d'obtenir un matériau composé de matière carbonée conductrice ; (b) mélanger le matériau composé de matière carbonée conductrice et un matériau formant une couche de surface ; et (c) procéder à la combustion du mélange obtenu à l'étape (b) afin d'obtenir le matériau d'électrode. L'invention porte également sur une batterie secondaire au lithium-ion comprenant une électrode qui comprend le matériau selon l'invention. |
