Abstract

The invention provides a flexible micro supercapacitor and a preparation method thereof. The preparation method comprises the following steps: orderly printing hydrophobic electrode isolation patternand hydrophilic interdigital electrodes on a hydrophilic flexible substrate, wherein the interdigital electrodes are arranged at two sides of the electrode isolation pattern; and orderly coating a gelelectrolyte layer and an encapsulation layer on the surfaces of the electrode isolation pattern and the interdigital electrode to form a flexible micro supercapacitor. The flexile micro supercapacitor can precisely regulate and control the structural parameter of the interdigital electrode, the preparation process simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of semiconductor devices, in particular to a flexible micro supercapacitor and a preparation method thereof. Background technique [0002] Supercapacitor 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] Supercapacitors include sandwich supercapacitors and planar supercapacitors. Compared with the sandwich supercapacitor, the planar supercapacitor can significantly reduce the thickness of the supercapacitor, and can also optimize the design of the interdigital electrode structure parameters to improve the energy density and power density of the supercapacitor, while having good flexibility and portability. The difficulty in the preparation of planar supercapacitors lies in the preparation of the interdigitated electrodes. At present, interdigitated electrodes are usua...
