Zusammenfassung:The present invention relates to a porous carbon body, and more specifically, to a porous carbon body satisfying the following three physical properties: a surface area physical property of pores having a size of 2 nm to 5 nm; a surface area physical property of pores having a size of 2 nm to 100 nm; and a physical property relating to a delta graph which is a graph of the values of a nitrogen desorption isotherm minus the values of a nitrogen adsorption isotherm in a nitrogen adsorption-desorption isotherm according to relative pressure. La présente invention concerne un corps de carbone poreux et, plus spécifiquement, un corps de carbone poreux satisfaisant les trois propriétés physiques suivantes : une propriété physique de surface de pores ayant une taille de 2 nm à 5 nm ; une propriété physique de surface de pores ayant une taille de 2 nm à 100 nm ; et une propriété physique relative à un graphique delta qui est un graphique des valeurs d'un isotherme de désorption de l'azote moins les valeurs d'un isotherme d'adsorption de l'azote dans un isotherme d'adsorption-désorption de l'azote en fonction de la pression relative. 본 개시는 다공성 탄소체에 관한 것으로, 상세하게, 2 nm 이상 내지 5 nm 이하 크기 기공의 표면적 물성, 2 nm 이상 내지 100 nm 이하 크기 기공의 표면적 물성 및 질소 흡탈착 등온선에서 상대압에 따른 질소 탈착 등온선의 값에서 질소 흡착 등온선의 값을 뺀 값의 그래프인 델타 그래프 상의 물성을 포함하는 세 물성을 만족하는 다공성 탄소체에 관한 것이다.
