PVDF Binder for Li-ion Battery Electrodes

Polyvinylidene fluoride (PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. PVDF is a specialty plastic used in applications needing the highest purity, as well as resistance to solvents, acids and hydrocarbons. PVDF is used as piping products, sheet, tubing, films, plate and an insulator for premium wire. PVDF is used in many different areas like in semiconductors, madical and defense industries. One of the important area that PVDF is used is lithium ion batteries as binder.
In lithium ion batteries the binder can be considered as a key component . The major function of the binders in lithium ion batteries is to act as an effective dispersion agent to connect the electrode species together and then steadily adhere them to the current collectors.
PVDF is one of the most commonly binders used for cathode of lithium ion batteries because of its superior electrochemical and thermal stability and good adhesion between the current collectors and electrode films.
By the adhesion between the current collectors and electrode films obtained by PVDF Binder for Li-ion Battery Electrodes the longer cycle life and higher energy density can be obtained at even lower PVDF binder addition. Also the polar functional groups in PVDF binder result in lower internal energy. Long‐term stability can be ensured by the PVDF's excellent chemical resistance in the aggressive environment of lithium ion batteries, which includes organic carbonates and lithium salts.

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...
