Problems solved by technology

[0002] The electrode technology of the existing micro-supercapacitor usually adopts scrape coating, screen printing, and 3D printing methods. The electrodes prepared usually contain conductive current collectors, such as aluminum foil, stainless steel mesh, and carbon fiber cloth. However, these electrodes usually not only contain additives (such as conductive agent carbon black, binder PTFE or PVDF), and it is relatively thick, poor flexibility, not conducive to installation and use in micro-supercapacitors, and its cost is high

Abstract

Provided is a MXene paper electrode and a preparation method thereof and a minitype supercapacitor and a preparation method, and mainly relates to the field of conducting materials. The preparation method of the MXene paper electrode prepares the MXene paper electrode by a spraying technology, so that the MXene paper electrode has the advantages that the MXene paper electrode is flimsy, flexible and low in cost; in addition, the minitype supercapacitor with paper support is prepared by overcoming the defect that most of traditional supercapacitor need current collectors, so that the minitype supercapacitor is flimsy and good in flexibility and the function of surface mounting technology of the minitype supercapacitor is easily achieved. Therefore, the MXene paper electrode and the preparation method thereof and the minitype supercapacitor and the preparation method have important promotion and application value and higher commercial value.
