Title:
GRAPHENE SHEET FILM LINKED WITH CARBON NANOTUBES, METHOD FOR PRODUCING SAME AND GRAPHENE SHEET CAPACITOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/073998
Kind Code:
A1
Abstract:
A graphene sheet film in which two or more graphene sheets (11-25) are stacked and the stack is film-shaped, wherein a graphene sheet stack (101) is used which comprises: first carbon nanotubes (31-48) which connect the graphene sheets (11-25) together and which form graphene sheet laminated bodies (61-65) in which the graphene sheets (11-25) are laminated such that the surfaces thereof are parallel with each other; and second carbon nanotubes (51-56) which link the graphene sheet laminated bodies (61-65) together. According to the present invention, a graphene sheet film with high capacitor properties associated with energy density and output density, a method for producing same and a graphene sheet capacitor using same can be provided.
