Carbonaceous electrode material for battery and process for production thereof

摘要

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 - 1400 DEG C) below the final carbonization temperature.
