Synergistic integration of molybdenum telluride grown on carbon nanofibers for high-performance flexible microsupercapacitors

Year: 2025

Type: article

Abstract: The growing demand for sustainable, flexible energy storage systems has intensified interest in microsupercapacitors (MSCs) due to their high-power density, long cycle life, and compatibility with wearable electronics. In this study, a high-performance, printable conductive ink was formulated using a MoTe 2 /carbon nanofiber (CNF) nanocomposite, combining the high conductivity and redox activity of MoTe 2 with the structural integrity and electric double-layer capacitance of CNFs. The ink exhibited excellent rheological properties (viscosity ≈ 6646.4 mPa.s at 25°C) and stable dispersion, enabling uniform screen-printing on flexible polyethylene terephthalate (PET) substrates. The resulting MSCs delivered a high areal capacitance of 203.28 mFcm -2 at 5 mVs -1 , with an energy density of 20.78 µWhcm -2 and a power density of 333.2 µWcm -2 . The devices retained 90.9% of their initial capacitance after 5000 charge-discharge cycles and maintained performance under repeated mechanical bending, confirming excellent flexibility and durability. This work demonstrates a scalable and eco-friendly route to fabricate flexible MSCs with enhanced electrochemical performance for next-generation portable electronics.
