Disclosed is a method for producing edge-functionalized graphite with phosphoric acid. According to the method, graphite is pulverized into smaller pieces and is then exposed to an atmosphere containing oxygen and water. The method enables the production of graphite functionalized with phosphoric acid groups, which could not be achieved by conventional mechanochemical methods. In addition, the method is carried out in a very simple and economical manner and is suitable for large-scale production.
