Abstract
The widespread deployment of flexible supercapacitors in wearable electronics remains hindered by their insufficient specific capacitance and inadequate long-term cycling stability. In this study, a poly(3,4-ethylenedioxythiophene)@siloxene (PEDOT@SiXNS) composite was prepared via a facile chemical oxidative polymerization method, and symmetric supercapacitors were constructed using carbon cloth as the flexible substrate. Characterization results showed that the PEDOT@SiXNS composite electrode exhibited a high specific capacitance of 396.4 F g–1 at 0.5 A g–1, outperforming pure SiXNS and PEDOT. This enhanced performance is attributed to the synergy between SiXNS and PEDOT:SiXNS serves as a high-surface area scaffold with abundant active sites for efficient ion adsorption, while PEDOT forms a continuous conductive network to accelerate charge transfer kinetics. The fabricated device retained 96.5% of its initial capacitance after 10,000 cycles at 5 A g–1, with stable electrochemical performance under 0–180° bending, benefiting from the composite’s structural stability, which arises from PEDOT’s excellent film-forming ability and SiXNS’s rigid two-dimensional (2D) mechanical scaffold. This synergistic mechanism provides a new strategy for developing high-performance silicon-based flexible energy storage devices for wearable electronics.
