METHOD OF PRODUCING ELECTRODE MATERIAL FOR LITHIUM-ION SECONDARY BATTERY AND LITHIUM-ION BATTERY USING SUCH ELECTRODE MATERIAL

摘要

There is provided a method for producing an electrode material for a lithium-ion secondary battery. The method comprises the following steps: (a) mixing components of a basic ingredient or active substance of electrode material and a conductive carbon material to obtain a conductive carbon material-composited material; (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.
