Lithium Manganese Oxide ( LiMn2O4 ) Powder for Li-ion Battery Cathode Applications

One of the components that can be used as cathode materials in lithium ion batteries is lithium manganese oxide. Lithium Manganese Oxide ( LiMn2O4 ) Powder for Li-ion Battery Cathode Application provide a low cost and it is an environmental friendly cathode material.

In lithium ion batteries manganese is one of the most common transition metals used because of having multiple oxidation states, which leads the possibility to intercalate more than one lithium atom, and obtaining a wide potential range between depending on the crystal structure and the chemical composition. Being not toxic and highly available makes manganese a good material can be used in lithium ion batteries.

Manganese may have oxidation states of 2+, 3+ and 4+. With different oxidation states of manganese it is possible to obtain different geometries that can be used in lithium ion batteries. Depending on the geometry around the central metal ion and its oxidation state, the manganese gives the possibility to exploit a higher number of redox couples which are not possible to be exploited with other transition metal elements. This situation is extremely important for the design of new materials for Li-ion batteries.

But manganese-based cathode materials may have a problem related to their stability because of Mn2+ dissolution in the electrolyte and the Jahn-Teller effect of the Mn3+ ion which limits their cycle life. Of course scientist have worked on this problem and they have found some solutions. These solution include doping or surface coating. Another aspect for this situation is to develop composite electrodes using structurally integrated layered Li2MnO3 and spinel LiMn2O4. The combination of these two structures provides increased structural stability during electrochemical cycling while achieving higher capacity and rate-capability.

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.
