Abstract

The invention provides a supercapacitor and a preparation method therefor. The supercapacitor comprises a flexible substrate, a gel electrolyte, a diaphragm and two electrode membranes, wherein the two electrode membranes are formed on the flexible substrate and are positioned on the two sides of the diaphragm oppositely and respectively; the gel electrolyte is formed on the electrode membranes and positioned between the electrode membranes and the diaphragm; the electrode membranes are formed by an electrode mixed solution which comprises carbon nanotubes and a conductive polymer; and the gel electrolyte is formed by a gel electrolyte mixed solution. Rapid and large-area preparation of the supercapacitor is realized.

Description

technical field [0001] The present application relates to the field of semiconductor devices, in particular to a supercapacitor and a preparation method thereof. Background technique [0002] Supercapacitor, also known as Electrical Double Layer Capacitor (Electrical Doule-Layer Capacitor), is a new type of energy storage device, which has the characteristics of short charging time, long service life, good temperature characteristics, energy saving and environmental protection. [0003] At present, when preparing electrodes for supercapacitors, the electrode layer is usually formed on the substrate by vacuum filtration, or the electrode layer is formed on the substrate by inkjet printing. Electrode layers cannot be prepared on flexible material substrates by vacuum filtration, and although inkjet printing can prepare electrode layers on flexible material substrates, the configuration process of the ink used is cumbersome and takes a long time to prepare. Rapid and large-are...
