Graphene Battery

Batteries have become an important part in our electricity dependent modern lives. Every electronic device ranging from cell phones to computers rely on batteries for electricity storage. Even automobiles sector is shifting toward electric vehicles as the oil depletion and the environmental issues increase. The need for better battery with higher capacity, more stability and faster charging rates is in continuous demand. The solution is definitely in the development of new materials that have excellent properties which can increase the performance of the batteries. Graphene represent one of the best materials with extraordinary properties for the development of the batteries.

Graphene has very high surface area, hundred times better conductivity than copper and show good flexibility properties. Making battery out of graphene is one of the choices that battery developments have been working on. So far, hundreds of researches have been done that show the increase of the capacity, stability and charging rates of the graphene embedded batteries. Commercially, a Chinese company named Gongxu optoelectronics announced the first graphene battery with 4,800 mAh capacity and can be recharged in 13-15 minutes. Another company from Spain called Graphenano claims that they will produce graphene polymer cells that have 1,000 watt-hours per kilogram which is five times that of current lithium-ion cells. These developments show the importance of implanting nanomaterials such as graphene in different applications which can lead to excellent improvements in our daily lives.

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.

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 that i

Magnesium Oxide Nanoparticles/Nanopowder and Applications

General Information about Magnesium Oxide Magnesium oxide which has the chemical formula of MgO, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of Magnesium. It is a white powder at room temperature. Magnesium Oxide has very high melting point (2825 o C) and boiling point (3600 o C). Magnesium Oxide Nanoparticles/Nanopowder and Usage Areas Magnesium Oxide nanoparticles/nanopowder can be used in many different areas. For example Magnesium Oxide nanoparticles/nanopowder are used as a fire retardant for chemical fiber and plastics trades. For making crucible, smelter, insulated conduit, electrode bar, and electrode sheet Magnesium Oxide Nanoparticles/Nanopowder can be used as electric insulating material. Magnesium Oxide nan
