“…Liu et al synthesized mesoporous vanadium oxide with pore sizes ranging from 3 to 4 nm by electrodepositing from a VOSO 4 solution in the presence of a block polyalkylene oxide polymer (P123). [74] This polymer surfactant plays a key role in the formation of mesoporous structure. The authors specifically investigated the rate performance of the mesoporous vanadium oxide electrode and found that the material delivered a capacity of 125 mA h g À1 at a high rate of 508C, corresponding to a capacitance of 450 F g…”

Developments in Nanostructured Cathode Materials for High‐Performance Lithium‐Ion Batteries

Nanostructured materials lie at the heart of fundamental advances in efficient energy storage and/or conversion, in which surface processes and transport kinetics play determining roles. This Review describes some recent developments in the synthesis and characterization of nanostructured cathode materials, including lithium transition metal oxides, vanadium oxides, manganese oxides, lithium phosphates, and various nanostructured composites. The major goal of this Review is to highlight some new progress in using these nanostructured materials as cathodes to develop lithium batteries with high energy density, high rate capability, and excellent cycling stability resulting from their huge surface area, short distance for mass and charge transport, and freedom for volume change in nanostructured materials.

“…Through the synthesis of electrode materials with nanoscale dimensions, the electrochemical performance of many materials has been greatly improved [17][18][19][20][21] . In recent years, with the rapid development of nanostructure synthesis, electrode materials from mesoporous nanostructures have attracted much attention since it has been shown to provide a significant increase in rechargeable lithium ion battery performance with respect to energy density, life cycle, and speed performance [22][23][24][25][26][27][28][29] . This comes as a direct consequence of a greater specific surface area leading to a concomitant increase in current density.…”

LiMn 2 O 4 with nanostructured morphologies possess rapid kinetics which is favorable for the intercalation of lithium ions in battery electrodes 1 . In this work, we have studied the effect of varying the amount of water in the hydrothermal synthesis of nanostructured LiMn 2 O 4 spinel. It was found that three distinct nanostructured morphologies of this compound are obtained when the volume of water used during the synthesis is varied. The powders were morphologically and structurally characterized using TEM, XRD, and BET yielding particle sizes ranging from 1 to 50 nm, with 90 % of the sample possessing a particle size of 21.7 nm. X-ray diffraction analysis show characteristic peaks and confirm the compound's identity and crystalline structure. Furthermore, the electrochemical behavior of this material in lithium ion batteries was studied. The results indicate that the electrochemical performance is strongly influenced by the size and shape of the α-LiMn 2 O 4 nanoparticles.

Carbon nanocage supported synthesis of V2O5 nanorods and V2O5/TiO2 nanocomposites for Li-ion batteries

We present the facile synthesis of crystalline V 2 O 5 nanorods and V 2 O 5 /TiO 2 nanocomposites structures by a carbon nanocage (CNC)-assisted growth process, using vanadium triisopropoxide oxide and titanium isopropoxide precursors in air at 500 C. The diameters of the resultant V 2 O 5 nanorods ranged between $10 and 70 nm, while the crystalline V 2 O 5 /TiO 2 nanocomposite structures adopted a unique morphology, due to both crystallisation and templating processes, with V 2 O 5 adopting small-diameter nanowire and nanorod morphologies surrounded by sub-30 nm TiO 2 nanoparticles. The V 2 O 5 nanorods and V 2 O 5 /TiO 2 nanocomposites were characterised by electron microscopy and X-ray diffraction techniques and subsequently reviewed as positive Li-ion electrodes. The phase-pure V 2 O 5 nanorod structures exhibited appreciable Li + storage properties over the potential range of 2.0-4.0 V vs. Li/Li + , displaying capacities of up to 288 mA h g À1 with appreciable cyclic behaviour at test rates of up to $1 C. The crystalline V 2 O 5 /TiO 2 nanocomposite structures displayed similar Li + storage properties, however, increasing molar fractions of TiO 2 led to a decline in the overall capacity versus the single-phase V 2 O 5 counterparts. Interestingly, the Li + insertion behaviour of the V 2 O 5 /TiO 2 nanocomposite displayed character more-typical of amorphous V 2 O 5 , which was ascribed to a structural buffering effect of the inactive TiO 2 phase.
