Lithium Iron Phosphate (LiFePO4 ) Micron Powder for Li-ion Battery Cathode Applications

The performance of lithium-ion batteries that we have started to use in electronics almost every day, depends on the properties of the materials that they are produced of. Generally the materials that are used for the production of lithium ion batteries are expensive to be produced and they offer limited energy storage possibility.

Thus, it is very important to develop new types of lithium ion batteries which should be simplified, efficient and environmentally friendly. For this purpose lithium iron phosphate which discovered in the late 1990s and is currently the most studied cathode material for lithium-ion batteries.

Lithium iron phosphate is a desirable cathode material due to its outstanding features, like low cost, superior thermal stability, enhanced safety, high theoretical specific capacity and suitable charge/discharge voltage plateau. Since there is a strong P-O covalent bond in lithium iron phosphate, it is thermodynamically and dynamically stable even at temperature above 200°C.

To get the best result in terms of electronic conductivity and cycle life from lithium iron phosphate cathode material there are some options that can be applied. For example carbon coating of lithium iron phosphate cathode can be shown as the most efficient method found up to now to do this. The electrochemical properties of the final lithium iron phosphate - carbon composites are strongly dependent on the quality of the carbon coating – its amount, morphology, degree of graphitization, and the distribution on the surface. By the coating of carbon on lithium iron phosphate cathode, you can end up with a cathode material with superior properties.

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

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.
