HIGH CAPACITY MICRO-SUPERCAPACITOR MANUFACTURING METHOD FOR HIGH CAPACITY MICRO-SUPERCAPACITOR AND FORMING METHOD FOR CURRENT COLLECTOR

摘要

The present invention relates to a method of manufacturing a micro-supercapacitor with an increased storage capacity of electrical energy. The method of manufacturing a micro-supercapacitor including an anode and a cathode separated from each other comprises: a current collector forming step of forming a pair of current collectors by discharging conductive ink on a substrate surface with a 3D printer; and an electrode forming step of forming 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. The present invention can form the electrode by the method of stacking the electrode in the plurality of layers using the 3D printer to form a micro electrode which is thick, thereby manufacturing the micro-supercapacitor with the increased energy capacity. In addition, an on-board process can be possible by reducing restrictions on the position for performing current collector and electrode formation. Furthermore, the present invention is advantageous in that there is no waste of material generated when the constituent material is shaved for the formation of the current collector or the electrode.
