“…and their derivatives have attracted increasing attention because they can be used as the electrode materials for electrochemical applications in recent years. As the intercalation compounds, V 3 O 7 Á H 2 O and VO 2 (B) are promising cathode materials in lithium-ion batteries [20,23,24,26,[55][56][57]. It was reported that the electrochemical properties of the electrode materials were influenced by many factors, such as intrinsic structure, morphology, and preparation methods.…”

“…Vanadium [15] are interesting electrode materials for lithium ion batteries because of its typical intercalation structure, low cost and tunable oxidation state (from +2 to +5). Among these, VO 2 and V 3 O 7 Á H 2 O have attracted much attention due to its potential application in transistors, electrical and optical switch devices and lithium ion battery [16][17][18]. VO 2 (B) is one of vanadium dioxide polymorphs [6].…”

“…In practical use for the Li battery, MoO 3 has poor ionic and electronic conductivity [22]. To improve the conductivity of MoO 3 , carbon nanotubes [11,23], graphene [24], or conducting polymer [25,26] could be the best choices of conductive fillers. Very recently, it was suggested that graphene, a new two-dimensional nanomaterial composed of sp 2 -hybridized carbon, could be employed as an excellent candidate for the preparation of metal oxide − graphene nanocomposites due to its high conductivity, large surface area, flexibility, and chemical stability [27].…”

Highly flexible, binder-free, MoO3 nanobelt/graphene film electrode is prepared by a two-step microwave hydrothermal method. Graphene is first prepared by an ultra-fast microwave hydrothermal method and then mixed with MoO3 solution to synthesize the MoO3 nanobelt/graphene composite, which exhibits the combination of stacked graphene sheets and uniform MoO3 nanobelts with widths of 200-500 nm and lengths of 5-10 μm. The charge-discharge measurements show that the as-synthesized MoO3/graphene hybrid materials demonstrate excellent rate capability, large capacity, and good cycling stability compared to the pure MoO3 film. An initial discharge capacity of 291 mAh g-1 can be obtained at 100 mA g-1, with a capacity of 172 mAh g -1 retained after 100 cycles. The results show that the MoO 3/graphene designed in this study can be used as a free-standing cathode material in rechargeable bendable Lithium batteries. © 2012 Published by Elsevier B.V.

(2013). Rapid synthesis of free-standing MoO3/ Graphene films by the microwave hydrothermal method as cathode for bendable lithium batteries. Journal of Power Sources, • A new method to synthesize high quality of MoO 3 nanobelts from commercial bulk.• Ultra-fast microwave hydrothermal method for fabrication MoO 3 /graphene films.• MoO 3 /graphene hybrid materials demonstrate good cycling stability as cathode. 3 IntroductionThe There are several reports on the hydrothermal synthesis of MoO 3 nanostructures to produce materials with high purity, homogeneity, good crystallinity, and unique properties [20,[38][39][40]. Microwave irradiation can be used as an alternative heat source for the 5 hydrothermal process [41,42]. It leads to a rapid heating to attain the desired temperature in a short time and increases the reaction kinetics compared to the conventional hydrothermal method. In a microwave-assisted hydrothermal reaction, the heating rate is extremely rapid, due to the dielectric property of the medium or solvent [41,42]. Recently, Phuruangrat et al. [43] reported MoO 3 nanowires 50 nm in diameter and 10-12 μm in length that were synthesized by the microwave assisted hydrothermal method with cetyl trimethylammonium bromide (CTAB) as the surfactant-template.Here, we present a new method to synthesize high quality MoO 3 nanobelts from commercial bulk MoO 3 without a surfactant-template and combine them with graphene via a two-step microwave hydrothermal method for fabrication of highly flexible free-standing MoO 3 /graphene films. The free-standing MoO 3 nanobelt/graphene films prepared by the above method followed by the vacuum filtration technique were investigated as a cathode material for bendable Lithium batteries and compared with MoO 3 nanobelt films prepared by a similar method ...
