Improved electrochemical performance of defect-induced supercapacitor electrodes based on MnS-incorporated MnO₂ nanorods.

ABSTRACT: In this paper, we report the effect of MnS nanoparticles on the electrochemical performance of 1D-MnO₂ stable nanorods for supercapacitor electrodes. The MnS-incorporated 1D-MnO₂ (MnO₂/MnS) nanorods were produced using a facile two-step hydrothermal method. Morphological investigation reveals that the incorporation of MnS nanoparticles distorts the lattice fringes and extends the interlayer spacing of the MnO₂ nanorods. The structural study showed that MnS modified the structural parameters of the nanocomposite. XPS analysis revealed defects in the nanocomposite due to the generation of oxygen vacancies. The MnO₂/MnS nanocomposite improves capacitive performance and has the highest specific capacitance of 305 F g^-1, at a cur
