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

In this paper, we report the effect of MnS nanoparticles on the electrochemical performance of 1D-MnO stable nanorods for supercapacitor electrodes. The MnS-incorporated 1D-MnO (MnO/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 MnO nanorods.

Superior Cyclic Stability and Capacitive Performance of Cation- and Water Molecule-Preintercalated δ-MnO/h-WO Nanostructures as Supercapacitor Electrodes.

The large number of active sites in the layered structure of δ-MnO with considerable interlayer spacing makes it an excellent candidate for ion storage. Unfortunately, the δ-MnO-based electrode has not yet attained the exceptional storage potential that it should demonstrate because of disappointing structural deterioration during periodic charging and discharging. Here, we represent that stable Na ion storage in δ-MnO may be triggered by the preintercalation of K ions and water molecules.

Hydrothermal synthesis of NiO nanoparticles decorated hierarchical MnO nanowire for supercapacitor electrode with improved electrochemical performance.

In this work, MnO/NiO nanocomposite electrode materials have been synthesized by a cost-effective hydrothermal method.

Multi-walled carbon nanotube (MWCNT) incorporated biodegradable gelatin nanocomposites (Gel/MWCNT) have been prepared following a facile solution processing method. The Fourier-transform infrared (FTIR) spectroscopy, field emission scanning electronic microscopy (FESEM), and water contact angle (WCA) measurements revealed improved structural properties and surface morphological features of the nanocomposite films due to the incorporation of MWCNT. A four-fold decrease in the DC resistivity was obtained due to the addition of MWCNTs.
