Lithium Cobalt Oxide Micron Powder for Li-ion Battery Cathode Application

Lithium cobalt oxide is a chemical compound with the chemical formula of formula LiCoO2. Lithium cobalt oxide is a dark blue or bluish-gray crystalline solid and is commonly used in the positive electrodes of lithium-ion batteries.

As all we may know lithium ion batteries are used in household electronics like mobile phones and laptop and these batteries are considered as the most promising energy storage and conversion device candidates for use in future electric vehicle applications because of having very high energy density.

In lithium ion batteries lithium cobalt oxide is one of the earliest founded lithium metal oxides used as cathode materials. The usage of lithium cobalt oxide started with the studies of Sony. Sony combined the lithium cobalt oxide cathode with a carbon anode and made the first successful lithium ion battery. It was a visionary study because this kind of battery now dominates the lithium battery market. Lithium cobalt oxide is preferred to use as cathode material in lithium ion batteries for its good performance and stability.

The studies on the usage of Lithium Cobalt Oxide Micron Powder for Li-ion Battery Cathode Application are still continued. Until now lithium cobalt oxide has been the subject of literally thousands of papers. Some studies are about the improvements in capacity and recharge ability of lithium cobalt oxide. One of the studies related to this field states that the capacity of lithium ion batteries where lithium cobalt oxide is used as cathode material could be improved by coating a metal oxide or phosphate on the surface of the lithium cobalt oxide particles.

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.
