1. A method for producing coated nano-ordered carbon particles, comprising:
exposing a carbon-containing material to an expanding agent to produce expanded carbonaceous particles during an expanding process;
heating the expanded carbonaceous particles during an annealing process; and
depositing a carbon film on the expanded carbonaceous particles with nano-ordered structure to produce coated nano-ordered carbon particles during a carbon coating process, wherein the carbon coating process includes a liquid deposition process.
