Vanadium Oxide Sputtering Targets and Applications

Vanadium oxide is the inorganic compound with the chemical formula of V2O5. It is a brown/yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange. Because of its high oxidation state, Vanadium Oxide (V2O5) Sputtering Targets (Size:1'' ,Thickness:0.125'' , Purity: 99.9%) is both an amphoteric oxide and an oxidizing agent. From the industrial perspective, it is the most important compound of vanadium, being the principal precursor to alloys of vanadium and is a widely used industrial catalyst.
Now let's look at one of the applications, thin film batteries, where vanadium oxide is used. Thin film batteries are composed of thin film cathode, anode and solid electrolyte. Most of the studies for thin film secondary batteries have been focused on preparation and electrochemical properties of thin film electrodes. This is because the discharge-charge capacity of thin film battery is mainly dependent on electrode materials. As the cathode electrode for lithium battery, lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4) and vanadium oxide (V2O5) have been studied. Among these, vanadium oxide sputtering target is a promising material for the cathode of thin film battery due to its high discharge capacity and good cycle performance. Moreover, it can be prepared at room temperature by vacuum system such as sputtering and such a low-temperature preparation is of great beneficial to on-chip applications. In the preparation of vanadium oxide films by radio frequency (RF) sputtering technique, the stoichiometry, structure and orientation of vanadium oxide can be influenced by the process parameters such as RF power, reactive gas atmosphere, temperature and substrate. The nature of vanadium oxide films can also affect their electrochemical properties. Therefore, a careful control is required to obtain high quality vanadium oxide thin films for battery application.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread th...

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product. Figure: Single Walled Carbon Nanotube (SWCNT) It ha...
