Abstract
A biomass-derived carbon material is provided, the carbon material having a carbon content of 60 to 75% by weight and an integrated heat of oxidation reaction of 5 kJ/kg or less when maintained in air at 107° C. for 20 minutes. A method for producing a carbon material is provided, the method including: a carbonization step of obtaining biomass chars having a carbon content of 61 to 75% by weight from biomass; and an oxidation step of heating the biomass chars to 200° C. or higher in an atmosphere having an oxygen concentration of 2 to 13% by volume.
