Screen-Printed Microsupercapacitors on Paper With Additive-Free 1T MoS2 Ink for Sustainable Energy Solutions
This study introduces a novel binder-free 1T molybdenum disulfide symmetric microsupercapacitor (1T MoS2 SMSC) fabricated on a flexible paper substrate. By fine-tuning the geometry of the electrode fingers and employing a quasi-solid 3M polyvinyl alcohol (PVA)-H2SO4 electrolyte, we have achieved high capacitance and excellent cyclic stability across various operational conditions. Electrochemical characterization, including cyclic voltammetry (CV) and chronopotentiometry (CP), revealed that the 1T MoS2 SMSC maintains nearly quasi-rectangular CV curves, indicating an ideal capacitive behavior. The device demonstrated a high areal capacitance of 22.5 mF
$\cdot $
cm−2 at 2 mV
$\cdot $
s−1. In addition, the series connections of the devices have shown promising performance metrics suitable for portable electronic applications, achieving significant energy and power density (PD) values.
