Flexible and transparent supercapacitor based on In2O3 nanowire/carbon

In this paper, a supercapacitor with the features of optical transparency and mechanical flexibility has been fabricated using metal oxide nanowire/carbon nanotube heterogeneous film, and studies found that the power density can reach 7.48 kW/kg after galvanostatic measurements. In addition, to study the stability of flexible and transparent supercapacitor, the device was examined for a large number of cycles and showed a good retention of capacity 88%. This approach could work as the platform for future transparent and flexible nanoelectronics

There has been great interest recently in both flexible and transparent electronics such as transparent and flexible active matrix organic light-emitting diode display which may find applications in heads-up display, automobile wind-shield display, and conformable products.1 However, to realize fully transparent and/or flexible devices, one may also consider making transparent and/or flexible energy conversion and storage units with high energy storage and power density.
Electrochemical capacitor supercapacitor with properties of high energy storage, small size, and lightweight has become one of the best candidates of energy storage devices.2–5. Although some supercapacitors built on carbon nanotubes CNTs have been reported,6–9 the performance of these supercapacitors is usually not as good as redox supercapacitors made of metal oxide materials e.g., RuO2, MnO2, and IrO2.10,11 On the other hand, these supercapacitors are usually neither transparent nor flexible, which greatly limit their real applications in flexible or transparent electronics. It is still of great interest to develop transparent and flexible supercapacitors.
