Abstract
A hard carbon. A total quantity of adsorbed nitrogen under a relative pressure P/Pof nitrogen between 10and 0.035 is Vcm(STP)/g and a total quantity of adsorbed nitrogen under a relative pressure P/Po of nitrogen between 0.035 and 1 is Vcm(STP)/g in a nitrogen adsorption isotherm determined at a temperature of 77 K for the hard carbon. The hard carbon satisfies: V/V≤0.20 and 20≤V≤150, where P represents an actual pressure of nitrogen, and Prepresents a saturated vapor pressure of nitrogen at a temperature of 77 K.
