摘要

PROBLEM TO BE SOLVED: To provide a method of producing a porous carbon material having excellent characteristics when used in electrochemical devices such as batteries or capacitors.SOLUTION: This invention provides a method of producing a porous carbon material having a specific surface area value of 10 m/g or more when measured by a nitrogen BET method, and a pore volume of 0.1 cm/g or more when measured by a BJH method and an MP method. In the method, a plant-derived material is subjected to heat treatment and converted to a carbonaceous material, and then treated with acid or alkali, in order to remove silicon components in the carbonaceous material, followed by applying activation treatment thereto.
