CARBONACEOUS MATERIAL, METHOD FOR PRODUCING SAME, AND ELECTROCHEMICAL DEVICE

The present invention relates to a carbonaceous material having a pore volume determined by performing Grand Canonical Monte Carlo simulation on an adsorption-desorption isotherm of carbon dioxide of 0.05 cm/g or more and 0.20 cm/g or less, and a ratio of desorption amount to adsorption amount (desorption amount/adsorption amount) at a relative pressure of 0.01 in the adsorption-desorption isotherm of 1.05 or more.
