ABSTRACT:
A battery electrode material having a large charge-discharge capacity and capable of providing a (non-aqueous solvent-type secondary) battery of a high energy density is provided in the form of a carbonaceous material having a microtexture suitable for doping with lithium (ions). Such a carbonaceous material is produced through a process of heating a starting organic material for carbonization including a step of heating the organic material in a halogen gas-containing inert gas atmosphere in a specific temperature range (800.degree.-1400.degree. C.) below the final carbonization temperature.
