Iron Sulfide Microspheres Supported on Cellulose-Carbon Nanotube Conductive Flexible Film as an Electrode Material for Aqueous-Based Symmetric Supercapacitors with High Voltage.

ABSTRACT: Nanostructured iron disulfide (FeS₂) was uniformly deposited on regenerated cellulose (RC) and oxidized carbon nanotube (CNT)-based composite films using a simple chemical bath deposition method to form RC/CNT/FeS₂ composite films. The RC/CNT composite film served as an ideal substrate for the homogeneous deposition of FeS₂ microspheres due to its unique porous architecture, large specific surface area, and high conductivity. Polypyrrole (PPy), a conductive polymer, was coated on the RC/CNT/FeS₂ composite to improve its conductivity and cycling stability. Due to the synergistic effect of FeS₂ with high redox activity and PPy with high stability and conductivity, the RC/CNT/FeS₂/PPy composite electrode exhibited excellent ele
