Anode material for lithium secondary battery, process for production thereof, and lithium secondary battery |
摘要 |
According to the present invention, there are disclosed: a process for producing an anode material for lithium secondary battery, comprising graphite particles and a crystalline carbon layer covering the whole surfaces of the graphite particles, wherein the whole surfaces of the graphite particles are covered with a carbon layer in a state that the surfaces of the graphite particles and the carbon 002 plane of the carbon layer are parallel, which process comprises subjecting graphite particles to a treatment for chemical vapor deposition in a fluidized bed type reactor at 900 to 1,200 DEG C, using a mixed gas consisting of an organic substance gas and an inert gas, the molar concentration of the organic substance gas in the mixed gas being 2 to 50%; and an anode material for lithium secondary battery, produced by the above process. <IMAGE> |
