Transparent Electrodes for Energy Storage Devices

Abstract

Transparent energy-storage devices have aroused interest because of the ever-increasing demands of transparent electronics. Transparent energy-storage electrodes (TESEs) are indispensable for emerging cutting-edge products and have thus attracted remarkable attention in the past decade. This minireview begins by introducing the basic evaluation metrics for TESEs. Then, recent progress of various types of TESEs such as carbonaceous materials, polymers, MXenes, and other conductive substrates-based TESEs is outlined. In order to provide some inspiration and guidelines, we focus on summarizing the presently proposed strategies towards high-performance TESEs together with the applications of transparent supercapacitors. At the end of this minireview, we discuss the outlook and perspectives towards the development of transparent energy-storage devices.

In Situ Observation of Morphological and Oxidation Level Degradation Processes within Ionic Liquid Post-treated PEDOT:PSS Thin Films upon Operation at High Temperatures

“…Whether in lightweight organic photovoltaics, − flexible organic light-emitting diodes, − organic sensors, − organic field-effect transistors, − transparent organic electrodes, − or organic thin-film thermoelectrics, − nowadays, organic semiconductors play a fundamental part in the development of new trendsetting devices and applications. The reason for this lies in the advantageous properties of organic semiconductors, like their easy and low-temperature processability from solution, facilitating a low-cost and energy-efficient fabrication with large-scale deposition techniques like printing, spray, or dip coating. , Furthermore, the raw materials are usually abundantly available and enable low or nontoxic, lightweight, and mechanical flexible devices.…”

Visibly transparent supercapacitors

“…The emerging demand for transparent optoelectronic devices urges technological innovations that lead to high optical transmittance without sacricing performance. 1,2 Transparent technology provides more visual information about electronic gadgets than conventional non-transparent ones. 3,4 An enormous effort has been made to transform non-transparent circuits, transistors, and displays to be almost visibly clear.…”

Inkjet-printed transparent micro-supercapacitors with morphology tailored co-continuous mesoporous Mn3O4

“…are the emerging elds that require reliable and transparent power sources. [1][2][3] In this regard, continuous efforts to power such emerging electronic devices have resulted in new research domains, such as high energy electronic devices like high energy and power density micro-batteries and microsupercapacitors. It is to be noted that high performance MSCs, prepared via high throughput solution processing techniques, such as spray coating, screen printing, inkjet printing etc., have primarily used different carbon allotropes or 2D semiconducting and conducting materials in the recent past.…”
