POROUS CARBON-BASED MATERIAL AND PRODUCTION METHOD OF POROUS CARBON-BASED MATERIAL
To provide a porous carbon-based material with which generation of fine powder can be prevented even when precursor powder having wide particle size distribution is used, and to provide a production method of the porous carbon-based material.SOLUTION: In a porous carbon-based material having secondary particles constituted by carbon-based particles and a carbonaceous binder making the carbon-based particles combine with each other, the secondary particles are not existing independently but combined with each other. A production method of the porous carbon-based material includes: a raw material forming step to obtain raw material powder by kneading the carbon-based particles and pitch with softening point of 70-200°C; a molding step to obtain a molding with a specified shape by putting the raw material powder in a molding tool and heating it to a temperature higher than the softening point; and a sintering step to sinter the molding.SELECTED DRAWING: Figure 2
【課題】広い粒度分布の原料粉を使用した場合でも、微粉末の発生を防止できる多孔質炭素系材料および該多孔質炭素系材料の製造方法を提供する。【解決手段】炭素系粒子と、炭素系粒子を互いに結合する炭素質バインダとが２次粒子を構成する多孔質炭素系材料は、２次粒子が、独立することなく互いに結合している。また、該多孔質炭素系材料の製造方法は、炭素系粒子と、軟化点が７０～２００℃のピッチとを混錬し、原料粉を得る原料工程と、前記原料粉を成形型に入れ、前記軟化点よりも高い温度に加熱し所定の形状の成形体を得る成形工程と、前記成形体を焼成する焼成工程と、を含む。【選択図】図２
