Anode material for lithium secondary battery, process for production thereof, and lithium secondary battery |
摘要 |
An anode material for lithium secondary battery, which comprises graphite particles and a crystalline carbon coating layer formed thereon, wherein each graphite particle has a bent laminate structure inside, is produced by grinding a graphite of 5 mm or less in average particle diameter using an impact grinder to produce graphite particles of 100 µm or less in average particle diameter having a bent laminate structure inside each particle and then subjecting the graphite particles to chemical vapor deposition in a fluidized bed type reaction furnace to form a crystalline carbon coating layer on the graphite particles. |
