“…Condensation via olation progressively decreases. Depending on the experimental conditions (pH and temperature) this leads to the formation of nanowires [42,43,44,45], nanofibres [46,47], nanoribbons [48], nanorods [49,50,51,52,53], nanobelts [54,55,56,57,58,59,60,61,62] and nanosheets [63]. …”

A wide range of vanadium oxides have been obtained via the hydrothermal treatment of aqueous V(V) solutions. They exhibit a large variety of nanostructures ranging from molecular clusters to 1D and 2D layered compounds. Nanotubes are obtained via a self-rolling process while amazing morphologies such as nano-spheres, nano-flowers and even nano-urchins are formed via the self-assembling of nano-particles. This paper provides some correlation between the molecular structure of precursors in the solution and the nanostructure of the solid phases obtained by hydrothermal treatment.

“…Approaches that provide interlayers that (i) coordinate Mg 2+ , (ii) shield interaction with the negatively charged host lattice, and (iii) remain as stable interlayer scaffolds are of significant interest. [38], polyethylene glycol [39], poly(3,4-ethylenedioxythiophene) [40], polypyrrole [41], and polyaniline [41,42] have been reported. The intercalation of PEO within the V 2 O 5…”

Rechargeable magnesium batteries provide the potential for lower cost and improved safety compared with lithium-ion batteries, however obtaining cathode materials with highly reversible Mg-ion capacities is hindered by the high polarizability of divalent Mg-ions and slow solid-state Mg-ion diffusion. We report that incorporating poly(ethylene oxide) (PEO) between the layers of hydrated vanadium pentoxide (V 2 O 5) xerogels results in significantly improved reversible Mg-ion capacities. X-ray diffraction and high resolution transmission electron microscopy show that the interlayer spacing between V 2 O 5 layers was increased by PEO incorporation. Vibrational spectroscopy supports that the polymer interacts with the V 2 O 5 lattice. The V 2 O 5-PEO nanocomposite exhibited a 5-fold enhancement in Mg-ion capacity, improved stability, and improved rate capabilities compared with V 2 O 5 xerogels. The Mg-ion diffusion coefficient of the nanocomposite was increased compared with that of V 2 O 5 xerogels and is attributed to enhanced Mg-ion mobility due to shielding interaction of PEO with the V 2 O 5 lattice. This study shows that beyond only interlayer spacing, the nature of interlayer interactions of Mg-ions with V 2 O 5 , PEO, and H 2 O are key factors that affect Mg-ion charge transport and storage in layered materials. The design of layered materials with controlled interlayer interactions provides a new approach to develop improved cathodes for magnesium batteries.
