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 le...

Graphite particles having a bent laminate structure inside each particle are produced by feeding, into an impact grinder, graphite particles having an average particle diameter of 5 mm or less together with a gas current to apply an impact to the graphite ...

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 th...
