The present invention is a technology for replacing a lithium ion secondary battery using an inorganic material, which is currently commercially available, and is a technology for constructing a secondary battery using an organic material as an electrode material. The organic electrode has a disadvantage in that the actual energy density is low because it has to include a large amount of carbon-based conductor in the electrode due to poor electrical conductivity. In order to overcome this drawback, in the present invention, the loading amount of the organic active material in the electrode is increased by filling the pores of the carbon structure body, such as porous activated carbon, with an organic electrode material and coating the outside of the carbon structure body with an organic electrode material. In addition, by using a carbon material current collector instead of the conventional metal current collector such as Al or Cu, a flexible and binder-free organic electrode was fabricated to increase the loading amount, reduce the weight of the battery, and improve the electrochemical properties.
