Abstract
The present invention provides a method for producing a random-structure GIC in which exfoliated graphite having a low regularity of a graphene stacked state and a small number of stacked graphene layers can be easily obtained by exfoliation treatment. The method includes the steps of providing an alkali metal-GIC having an alkali metal intercalated between graphene layers and bringing a polar protic solvent into contact with the alkali metal-GIC in a non-oxidizing atmosphere.
