Problems solved by technology

But these solid gels have rheological and labile characteristics, making it difficult to control the thickness of these gel electrolyte membranes sandwiched between two electrodes, which in turn makes it difficult to reproducibly manufacture supercapacitors with good stability.
In addition, the uncontrollability of the electrode spacing also restricts the optimization of device performance.

Abstract

The invention discloses a method for preparing a transparent supercapacitor with PS microspheres being an electrode spacing material and belongs to the field of transparent supercapacitor diaphragms and preparation methods thereof. According to the method, the material is mixed with a LiCl / PVA sol electrolyte through a stirring heating method; on the basis of the mixture, single-walled carbon nano tubes (SWCNTs) and indium tin oxide (ITO) glass are used as an active material and a current collector respectively to prepare the transparent supercapacitor; and the light transmittance of the capacitor is controlled by changing the quantity for spray of the SWCNTs. The method has high potential value thanks to the advantages that the material can precisely control electrode spacing, the all-solid-state transparent supercapacitor with good performance can be obtained, the raw materials are easy to obtain, and the method is beneficial for accelerating commercialization of the transparent supercapacitor.

Description

technical field [0001] The invention belongs to the field of a transparent supercapacitor diaphragm and a preparation method thereof, in particular to a method for preparing a transparent supercapacitor using polystyrene (PS) microspheres as an electrode spacer material, and controlling the light transmittance of the capacitor by changing the spraying amount of SWCNT . Background technique [0002] Transparent electronic devices are full of technology and appeal to consumers, which has become a new trend in the development of electronic products. The transparent display and touch unit are integrated with windows, coffee tables, windshields and clothing, so that any required information can be obtained anytime and anywhere, showing better portability and practicality. The opening and operation of transparent electronic devices is inseparable from the support of power supply, so the development of transparent power supply has become an important frontier topic in this field. ...
