High-quality graphite with similar crystal orientation is formed around the single crystal graphene (red box).

A Korean research team has developed new high-quality graphite used in the production of smartphones. Graphite is used for battery electrodes and smartphone heat sinks, affecting the quality of smartphones.

Ulsan National Institute of Science and Technology (UNIST) announced on Feb. 6 that a team led by Distinguished Professor Rodney Ruoff at the UNIST College of Natural Sciences, who leads the IBS Center for Multidimensional Carbon Materials, has developed a technology to produce high quality graphite with aligned graphite crystals by heat treating single crystal graphene.

UNIST explained that most materials, including graphite, have a multi crystal structure.

Ruoff said, "Given the numerous applications and demands of graphite, production of large high-quality single crystal graphite films is an important technology. By synthesizing graphite, which has been produced in a flake form in the past, in the form of large film and single crystal, the technology will also make a big contribution to the industry."
