Outline of Final Research Achievements	We synthesized graphene intercalation compound and electrode material which attracted conductivity by contribution of inclusion in addition to transparency and flexibility peculiar to graphene. In particular, reviewing the conventional process of preparing graphene intercalation compounds from graphene, graphene intercalation compounds were prepared by liquid phase exfoliation of graphite intercalation compounds capable of mass production. We developed a method of peeling while maintaining the intercalation compound structure in the liquid phase by introducing protective film on the surface of exfoliation and using chemical modification.
