Conductive Carbon Black for Lithium Ion Battery Applications

Nowadays there is a rapid development in lithium ion batteries because of their usage in electronics like mobile phones and electric vehicles. There are basically anode and cathode parts of lithium ion batteries and when we look at the cathode part we can see that it consists of particles of active material and inactive materials. For inactive materials we can give conductive additives as an example.
Conductive additive plays a role in increasing in the electric conductivity. For conductive additives carbon black can be given as an example. Conductive Carbon Black for Lithium Ion Battery Applications optimizes the electrical conductivity of the positive electrode but is not involved in the electrochemical redox process in lithium ion battery.
Actually the main duty of carbon black in lithium ion battery is to contribute to enhancing the cathode cyclability by filling the free spaces in between the particles of active material. So by this action the electrode conductivity increases.
Carbon black is a good choice to be used as conductive material in lithium ion batteries due to their low cost, low weight, high chemical inertness and property of being nontoxic. Also carbon black provides higher battery capacity and rate capability. To have a higher battery stability and high voltage charging for high energy carbon black will be a good choice. In some studies it has been observed that carbon black improves the battery cycle life. Since carbon black has low weight, you may load higher solids which enables higher coating speeds and this reduces battery manufacturing cost.

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...
