Flowers Like α-MoO3/CNTs/PANI Nanocomposites as Anode Materials for High-Performance Lithium Storage

Molecules, Journal Year: 2023, Volume and Issue: 28(8), P. 3319 - 3319

Published: April 8, 2023

Lithium-ion batteries (LIBs) have been explored to meet the current energy demands; however, development of satisfactory anode materials is a bottleneck for enhancement electrochemical performance LIBs. Molybdenum trioxide (MoO3) promising material lithium-ion due its high theoretical capacity 1117 mAhg-1 along with low toxicity and cost; it suffers from conductivity volume expansion, which limits implementation as anode. These problems can be overcome by adopting several strategies such carbon nanomaterial incorporation polyaniline (PANI) coating. Co-precipitation method was used synthesize α-MoO3, multi-walled CNTs (MWCNTs) were introduced into active material. Moreover, these uniformly coated PANI using in situ chemical polymerization. The evaluated galvanostatic charge/discharge, cyclic voltammetry (CV) impedance spectroscopy (EIS). XRD analysis revealed presence orthorhombic crystal phase all synthesized samples. MWCNTs enhanced material, reduced changes increased contact area. MoO3-(CNT)12% exhibited discharge capacities 1382 961 at densities 50 mAg-1 100 mAg-1, respectively. coating stability, prevented side reactions electronic/ionic transport. good MWCNTS stability make appropriate application

In this work, we report the properties of molybdenum disulfide (MoS2) thin films deposited on p-type silicon substrate using RF magnetron sputtering. The structural, vibrational and morphological MoS2 were investigated Raman spectroscopy, X-ray diffraction technique (XRD), atomic force microscope (AFM) scanning electron (SEM). spectroscopy result showed appearance broad E12g A1g peaks even without DC biasing becomes sharp distinct when is biased at 60 V. Post-deposition annealing in sulfur ambient resulted confirming formation film improved Mo-S bonding top surface. spectra samples validates with [002] XRD peak, substrates are biased. Improved effects reduction nano-sized defects, advent continuous low surface rms roughness value 0.872 nm, observed post annealing. A back-gated transistor was fabricated Al as source-drain contacts semiconducting channel. exhibited transfer characteristics threshold voltage −3.8 As a exposure, MoO3 fragments thinned layer extraction hole from MoS2, resulting behavior transistor. combination analysis, measurements EDS data confirmed inclusions film.

Morphological impact on energy storage properties of 2D-MoS₂ and its nanocomposites: a comprehensive review

Zeitschrift für Naturforschung A, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 19, 2025

Abstract Two-dimensional transition metal dichalcogenides (TMDCs) stand as pivotal materials with extraordinary physical and chemical properties, showcasing immense potential across various fields including sensors, catalysts, medicine, energy storage, conversion. Among these, molybdenum disulfide (MoS 2 ), a prominent TMDCs member, has captured considerable attention due to its graphene-like layered structure, small band gap (∼1.8 eV), superior theoretical capacity relative graphene. This review paper meticulously presented an analysis of MoS structural properties encompassing phases 2H (hexagonal), 1T (trigonal), 3R (rhombohedral) alongside their respective lattice constants. Additionally, diverse synthesis approach like hydrothermal, sol–gel, solvothermal methods have been discussed. The primary emphasis this applications in specifically role lithium-ion batteries supercapacitors. underscores the significant impact advancing energy-related technologies hints at catalysts sensors for medical conversion applications.
