Abstract: Disclosed is a 3-D printing apparatus. The apparatus includes an ink output module including an ink supply unit having an ink for forming an electrode portion, electrolyte or packaging portion received therein and an ink discharge unit coupled to the ink supply unit; a driving unit having the ink output module mounted thereon to move the ink output module in an X, Y, Z axis direction with respect to a substrate where a supercapacitor or secondary battery will be formed; a dispenser connected to the ink supply unit to supply gas having controlled pressure to the ink supply unit through a gas supply tube and to supply the ink within the ink supply unit through the ink discharge unit; and a controller controlling the output of the ink by transmitting a control command for fabricating the supercapacitor or the secondary battery to the dispenser and the driving unit.

Abstract: Disclosed are a flexible electrode substrate including a porous electrode, a method for manufacturing the flexible electrode substrate, and an energy storage element including the flexible electrode substrate. The flexible electrode substrate can be attached to various objects due to the excellent electrochemical properties and the adhesive properties thereof and thus is very useful. In particular, since the flexible electrode substrate can be used as an electrode of an energy storage element, an energy storage element including the flexible electrode substrate can be attached to various objects and thus can be used as a sticker-type energy storage element. In addition, the flexible electrode substrate can be easily manufactured by transfer method using a difference in adhesive strength and thus allows a simple manufacturing process thereof. Furthermore, electrodes having various patterns can be manufactured with high level of efficiency through simple adjustment of the manufacturing process.

Abstract: Disclosed herein is a method of manufacturing a micro-supercapacitor with an increased storage capacity of electrical energy. The method is a method of manufacturing a high-capacity micro-supercapacitor including an anode and a cathode separated from each other, which includes forming a pair of current collectors by discharging conductive ink on a substrate surface with a 3D printer, and forming an electrode consisting of an anode and a cathode by stacking an electrode constituting material in the form of a plurality of layers on each of the pair of current collectors using the 3D printer.
