PURPOSE: Cathode active agent, manufacturing method thereof, and lithium ion capacitor comprising the same are provided to control intercalation of the lithium ion entering the cathode active agent by forming amorphous structure at the micro region excluding crystal lattice. CONSTITUTION: The cathode active agent comprises porous structured active agent surface. The cathode active agent has the amorphous structure excluding the crystal lattice inside. The crystal lattice exists within the micro region. The cathode active agent comprises the natural alicyclic compound, the synthetic polymer, the carbon black, the glassy carbon, the Chars and at least one selected group of non-graphitizable materials comprised of coal. |
