General description

Carbon nanochips consist of wrapped graphite sheets oriented perpendicular to the fiber axis. Carbon nanochips are formed when platelet graphene or graphite nanofibers are heated in argon to about 3000°C, resulting in a sealing action of some of the edge sites and also removes all traces of inclusions such as the catalyst that is used to grow the precursor graphite nanofibers.

Application

  • Negative electrode for lithium ion secondary batteries.
  • Catalyst for ethylene oxidative dehydrogenation.
