Abstract

The invention relates to a method for using double-medium jet plasma to prepare a flexible supercapacitor composite electrode. The method includes placing a carbon nanomaterial to be deposited in an aerosol generator; selecting a working gas and a high voltage power supply, and adjusting discharge parameters and a working gas flow rate; selecting a substrate material, and placing the material under or at one side of a pipe orifice nozzle of a plasma jet pipe; switching on the high voltage power supply, generating plasma under or at one side of the plasma jet pipe, setting the movement path and movement speed of a movement platform, and depositing the carbon nanomaterial on the substrate material; and placing a precursor in the aerosol generator, repeating the Step 2, and adopting the movement path of the movement platform in the Step 4 to further deposite a metallic oxide or conducting polymer on the carbon nanomateiral to obtain a supercapacitor composite electrode. The method for using double-medium jet plasma to prepare the flexible supercapacitor composite electrode has the advantages of wide range of application, good deposition effect, simple and convenient operation, energy conservation and environment protection and the like, and has enormous potential application value.

Description

technical field [0001] The invention relates to a method for preparing a composite electrode of a flexible supercapacitor by dual-medium jet plasma. Background technique [0002] In recent years, with the rapid development of flexible electronics science and the miniaturization technology of electronic products, wearable, foldable, flexible, and portable electronic devices have become more and more popular, and the development of light, thin, flexible, high-performance devices that can provide energy for them Energy storage devices have become a research hotspot in academia and industry, and flexible supercapacitors are one of the most promising directions. Many small wearable smart devices and various micro-implanted devices require functional devices to be used stably under various deformation conditions, and traditional hard energy storage devices generally cannot meet these conditions, which greatly limits the ability of these micro-implants. Device efficiency and devel...
