Abstract: A preparation method of an artificial graphite includes heat-treating a graphite raw material to obtain artificial graphite, where an ambient atmosphere of the heat treatment is a mixed gas including a gas that is at least one of oxygen or water vapor and including a chemically inert gas, and, during the heat treatment, the graphite raw material is in a motion state.
