Carbon material for electrode and method for producing same, battery electrode and method for producing same, and battery and method for producing same

摘要

The electrode carbon material of the present invention is an electrode carbon material to become a constituent material for an electrode of a nonaqueous electrolyte battery, wherein the electrode carbon material is formed by way of a plasma processing step of subjecting a material composition to high-frequency thermal plasma processing in a plasma gas atmosphere including a sulfur-containing compound.
