To provide a manufacturing method of a carbonaceous anode material for a secondary battery having advantage in a high bulk density, minimum use of a binder having no direct contribution to a charge-discharge capacity, and a rapid charge-discharge characteristic, and a lithium secondary battery using the carbonaceous anode material produced by the manufacturing method.
The manufacturing method of the carbonaceous anode material for the secondary battery comprises a metal or semimetal oxide powder of 1-25 pts.wt. is added to and mixed with the carbonaceous material substantially having no softening point of 100 pts.wt., a resultant mixture is calcined in a nonoxidizing atmosphere, further graphitization is carried out at 2800-3200°C to obtain the carbonaceous anode material.
