HP-MoO2: A High-Pressure Polymorph of Molybdenum Dioxide

“…5,[9][10][11][12][13] It can be found in the mineral tugarinovite (named after the geochemist Alexsey Ivanovich Tugarinov) 14 and shows a metal-like electric conductivity being unusual for transition-metal oxides. 15,16 It does not have a variety of technological applications such as MoO3 but there are some interesting approaches for usage as anode material in lithium-ion batteries, 15,[17][18][19][20] films for energy storage, 21 soft-magnetic and optical materials, [22][23][24] and as nanorods. 22,25 The synthesis of other oxides with metal ions in just one oxidation state probably cannot be achieved by conventional chemical methods, like oxidation or reduction.…”

Hydrothermal synthesis and electrochemical properties of α-MoO3 nanobelts used as cathode materials for Li-ion batteries

“…Lithium ion batteries are used in a wide range of portable electronic devices, including mobile phones, laptop computers, and video cameras [1,2]. It is well known that the electrochemical properties of lithium-ion batteries strongly depend on the synthetic conditions, such as starting materials, test temperatures, lengths of times, and cooling rate [3].…”

“…It is well known that the electrochemical properties of lithium-ion batteries strongly depend on the synthetic conditions, such as starting materials, test temperatures, lengths of times, and cooling rate [3]. To improve the capability of batteries to get high power density, utilization of nanostructured materials with small particle size and large surface area is considered, in order to reduce diffusion distance of ions [1,2], including to increase electrochemical activity and charge/discharge efficiency [4]. It was demonstrated that the rate capabilities of nanostructured electrodes were improved, comparing to their bulk counterparts.…”

“…It was demonstrated that the rate capabilities of nanostructured electrodes were improved, comparing to their bulk counterparts. The improvement of rate capability is associated with large surface area and short diffusion path length in the nanostructured materials [1,5]. Especially, one-dimensional nanomaterials have attracted great interest because of their unique physicochemical properties, arising from their high surface area, novel size effects, and significantly enhanced kinetics [6].…”

The Role of Nanostructure in Improving the Performance of Electrodes for Energy Storage and Conversion

“…Due to the different experimentation, a direct comparison is not possible, but in general, all these tin-oxide-based anodes for Li-ion batteries show interesting performance and stability. Other nanostructured metal oxide anodes investigated recently include nickel oxide nanowires (diameter about 25 nm), [97] nanosized MoO 2 , [98] iron oxide nanoflakes [99] or nanotubes, [100] manganese oxide nanofibres, [101] Cu 2 O nanorods [102] and various mixed oxide nanosized materials, such as ZnFe 2 O 4 [103] with spinel structure and metal-doped Li 2 Ti 3 O 7 [104] with ramsdellite structure. Interesting properties are also shown by oxyfluorides such as TiOF 2 and NbO 2 F. [105] It should be noted that the data do not provide a full comparison, in terms of performance and stability, to determine the preferable class of materials.…”
