Abstract

Owing to advances in technology, people focus more on electronic devices that are both aesthetic and functional. Therefore, stretchable and transparent electronic devices have been widely used in wearable devices, transparent displays, and other fields. In the meanwhile, stretchable and transparent energy storage devices are developed to support those electronic devices. Therefore, this study aims to fabricate stretchable and transparent supercapacitors with high electrochemical performance.Conductive polymer poly(3,4-ethylene dioxythiophene) (PEDOT) doped with poly(styrene sulfonate) (PSS) is a promising candidate for the transparent electrode of supercapacitors as it is highly transparent, stretchable and provides well electrochemical performance. However, the PEDOT:PSS electrode suffers from low capacitance. This study focus on combining PEDOT:PSS with nano-metal oxides as hybrid electrodes. All-solid-state asymmetric supercapacitors assembled with those hybrid electrodes and gel electrolyte are highly transparent, stretchable and possess superior electrochemical performance. This research demonstrates the great potential of highly stretchable and robust all-solid-state asymmetric supercapacitor based on PEDOT:PSS/nano-metal oxide composite electrodes.
