Enhanced electrochemical activities of morphologically tuned MnFe₂O₄ nanoneedles and nanoparticles integrated on reduced graphene oxide for highly efficient supercapacitor electrodes

Abstract

The morphology of a nanoparticle strongly controls the path ofelectronic interaction, which directly correlates to the physicochemical properties and also the electrochemical comportment. Conjoining it with a two-dimensional (2D) material...

Deep eutectic solvent mediated synthesis and fabrication of a WO3–MgO nanocomposite as an electrode material for energy storage applications

“…In the high frequency region, there exists a combination of both the resistive and the capacitive properties. 56…”

“…In the high frequency region, there exists a combination of both the resistive and the capacitive properties. 56 3.12 GCD analysis and cycling stability GCD analysis is considered to be a practical approach to understand the capacitive behaviour of any material. 57 The GCD profiles of WO 3 and WO 3 -MgO have been recorded in the potential range 0-0.5 V at different current densities from 1 to 10 A/g as presented in Fig.…”

Improved Electrochemical Performance of Ni2P2O7 and Mn‐doped Ni2P2O7 Electrode Materials for Supercapacitor Applications

“…[19,36,37] Trasatti method is employed to explore the significant contribution of capacitive type charge storage mechanism in the prepared thin films. [32,38,39] The capacitive and intercalation current with respect to potential i(V) at a fixed scan rate can be calculated using the relation i…”

“…Trasatti method is employed to explore the significant contribution of capacitive type charge storage mechanism in the prepared thin films [32,38,39] . The capacitive and intercalation current with respect to potential i(V) at a fixed scan rate can be calculated using the relation $$$\vcenter{\openup.5em\halign{$\displaystyle{#}$\cr {\rm i}\left({\rm V}\right)={{\rm S}}_{1}{\rm v}+{{\rm S}}_{2}{\rm \ }{{\rm v}}^{1/2}\hfill\cr}}$$$ …”

NiTiO3/MnFe2O4 ferrite composites: synthesis, optical, ferroelectric and magnetic properties

“…Manganese ferrite (MnFe 2 O 4 -MFO) ceramic is a spinel ferrite material which is one of the important magnetic oxides, with specific physical and chemical properties [12,13]. MnFe 2 O 4 has soft magnetic properties with low coercivity, high magnetic permeability, and moderate saturation magnetization [14,15]. This material can be employed as a magnetic phase in composite materials to enhance magnetic properties.…”
