METHOD OF MANUFACTURING CARBON MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a carbon material by treating polyvinyl alcohol (PVA) based resin with halogen and then heat-treating, wherein a high carbonization yield is attained in a short time halogenation. SOLUTION: Before the halogenation, ≥0.7×10-2mol of at least one kind of a metal salt selected from alkali metal salts and alkaline earth metal salts is incorporated per 1 mol structural unit of the PVA based resin.
