Large‐area freestanding graphene papers (GPs) are fabricated by electrospray deposition integrated with a continuous roll‐to‐roll process. Upon mechanical compaction and thermal annealing, GPs can achieve a thermal conductivity of as high as 1238.3–1434 W m −1 K −1 . The super‐thermally conductive GPs display an outstanding heat‐spread ability and are more efficient in removing hot spots than Cu and Al foils.
