Abstract

See full text

A method for producing porous graphite capable of realizing higher durability, output and capacity, and porous graphite. A carbon member having microvoids is obtained by a dealloying step for selectively eluting other non-carbon main components into a metal bath by immersing a carbon-containing material, composed of a compound including carbon or an alloy or non-equilibrium alloy, in the metal bath, wherein the metal bath has a solidifying point lower than the melting point of the carbon-containing material, and is controlled to a temperature lower than the minimum value of a liquidus temperature within a composition fluctuation range extending from the carbon-containing material to carbon by reducing the other non-carbon main components. The carbon member obtained in the dealloying step is graphitized by heating in a graphitization step. The carbon member graphitized in the graphitization step is subjected to activation treatment by an activation step.
