Abstract: The present invention relates to a lithium-sulfur ultracapacitor including a cathode containing a sulfur-porous carbon composite material; a separator; a lithium metal electrode disposed on an opposite side of the cathode with respect to the separator; a graphite-based electrode disposed adjacent to the lithium metal electrode; and an electrolyte impregnating the cathode, the lithium metal electrode, and the graphite-based electrode, wherein the lithium metal electrode and the graphite-based electrode together constitute an anode, and a method of preparing the lithium-sulfur ultracapacitor. According to the present invention, since the lithium metal electrode and the graphite-based electrode are adjacent to each other, lithium ions arising from the lithium metal electrode are pre-doped on the graphite-based electrode due to an internal short circuit between the lithium metal electrode and the graphite-based electrode, migrate from the graphite-based electrode to the cathode during a discharging process, and migrate from the cathode to the graphite-based electrode during a charging process, and such migrations contribute to excellent charging and discharging properties of the lithium-sulfur ultracapacitor.
