چکیده

In this article, oval-shaped V2O5 nanoparticles were hydrothermally synthesized using a metal-organic framework (MOF), which was then followed by calcination under an air atmosphere. The obtained sample characterized through various characterization techniques to determine the purity and structural morphological details. Since possesses layered crystal structure, it exhibits promising electrochemical performances as cathode material for lithium-ion battery applications. However, poor cycling inferior rate capabilities are major issues that limit its application. Thus, strategy fabricate unique employed here improve MOF, acts template provides skeleton growth of novel nanostructure. It is believed morphology beneficial achieving better results due large surface area existence numerous channels lithiation de-lithiation. result reveals electrode can be considered prominent next-generation

Reduced graphene oxide supported highly porous V2O5 spheres as a high-power cathode material for lithium ion batteries.

Reduced graphene oxide (rGO) supported highly porous polycrystalline V(2)O(5) spheres (V(2)O(5)/rGO) were prepared by using a solvothermal approach followed by an annealing process. Initially, reduced vanadium oxide (rVO) nanoparticles with sizes in the range of 10-50 nm were formed through heterogeneous nucleation on rGO sheets during the solvothermal process. These rVO nanoparticles were oxid...

Spinel LiNi0.5Mn1.5O4 Cathode for High-Energy Aqueous Lithium-Ion Batteries

DOI: 10.1002/aenm.201600922 considering the overpotential during charge process. Recently, Yamada et al. reported that LiNi0.5Mn1.5O4 can only reversibly provide capacity of ≈75 mA h g−1 in the more concentrated hydrate melt electrolytes (≈30 mol kg−1), which is 50% of theoretical capacity.[14] The oxygen evolution side reaction also largely significantly reduce the coulombic efficiency. In add...

Controllable Preparation of V2O5/Graphene Nanocomposites as Cathode Materials for Lithium-Ion Batteries

Transition metal oxides and graphene composites have been widely reported in energy storage and conversion systems. However, the controllable synthesis of graphene-based nanocomposites with tunable morphologies is far less reported. In this work, we report the fabrication of V2O5 and reduced graphene oxide composites with nanosheet or nanoparticle-assembled subunits by adjusting the solvotherma...
