NOVELTY - The utility model a three-dimensional superconducting graphite structure, comprising a graphene film, the graphene film is provided with multiple filling holes along the thickness direction of the graphene film, the filling hole is a through hole, the multiple filling holes are arranged according to the way of rectangular array, the hole diameter of the filling hole is 1-100 microns, the filler hole is provided with graphite oxide filler. The utility model through drilling on the graphene, and then adding graphite oxide filler in the hole to obtain the three-dimensional superconducting graphite structure, the three-dimensional superconducting graphite structure can greatly improve the longitudinal heat conductivity, satisfying the use requirement of high thickness occasion.
