Abstract

The invention discloses a preparation method of an integrated asymmetric supercapacitor, and the method comprises the steps: enabling two integrated supercapacitors with different electrode materials to be cut apart along an electrolyte through the self-healing performance of the electrolyte, and enabling the two supercapacitors with different electrode materials to be connected through the self-healing performance of the electrolyte, and a new asymmetric supercapacitor can be assembled. And meanwhile, the problems that the voltage window of the integrally prepared supercapacitor is small and the supercapacitor assembled by a lamination method is easy to deform are solved. The method has the advantages of simplicity, high efficiency and high cost performance. The material prepared by the method has the characteristics of wider working voltage, higher energy density and power density, foldability, self-healing and the like.

Description

technical field [0001] The invention belongs to the field of supercapacitor new material energy storage, and in particular relates to a preparation method of a flexible integrated asymmetric capacitor. Background technique [0002] In recent years, stretchable and healable electronics have attracted much attention due to their excellent flexibility, high reliability, and stable resistance to deformation. In order to better meet the functional requirements of the above-mentioned electronic devices, it is an urgent need for researchers to develop corresponding energy storage devices with stretchable and repairable properties. Currently, self-healing flexible supercapacitors have been widely studied due to their long-cycle stability, fast charge-discharge, high power density, and self-recovery ability after continuous mechanical deformation or physical damage. [0003] Conventional flexible supercapacitors usually have a layered multilayer structure consisting of a polymer ele...
