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.

Rundown about Silicon Oxide Wafer

The main insulating material used in micro-technology is Silicon Dioxide, which in chemical symbols is written as SiO2. In semiconductor technology, SiO2 thin film layers are mainly used as dielectric material film in transistors, capacitors (DRAM) or flash-memories. Silicon Oxide Wafers are produced using crystallization, solid state and other ultra-high purification processes such as sublimation. This process forms a cylindrical ingot, which is then sliced and polished to form wafers. Thermal oxide is a kind of "grown" oxide layer, compared to CVD deposited oxide layer, it has a higher uniformity, and higher dielectric strength, it is an excellent dielectric layer as an insulator . In most silicon- based devices, thermal oxide layer play an important role to pacify the silicon surface to act as doping barriers and as surface dielectrics. The simplest way to produce an insulating silicon oxide layers (SiO2) on silicon wafers is to oxidize silicon with oxygen, which ...

New Way of Deaf-Mute Communication with 3D Graphene

Image retrieved from: http://blogs.rsc.org/cc/2016/09/01/3d-graphene-adds-dimension-to-deaf%E2%80%93mute-communication/ Chinese scientists have developed wearable electronic device with conductive 3D graphene structure to translate sign language into written text. This technology can be applied by injecting graphene ink from a syringe under printed electronic field. For medical field, such as adhesive patches which determine heart, brain signal and neural activity, wearable and bio-integrated medical devices are very important. Due to noticeable properties of cast graphene, for example a 2D honeycomb lattice, excellent mechanical and electrical behaviors, Graphene has an important material in warble technology. However, it is difficult to preserve advantages of Graphene material in a 3D material which has an information about forces from every angle. Yanlin Song  and co-workers at the University of the Chinese Academy of Sciences, Beijing, and Shenyang Jianzhu University...
