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.

Bismuth Oxide Sputtering Targets and Applications

Bismuth oxide with the chemical formula of Bi 2 O 3  is one the most important bismuth compounds. Bismuth oxide has been investigated extensively due to its optical and electrical properties such as large energy gap (from 2 to 4 eV), refractive index and high oxygen ion conductivity at high and medium temperatures. These properties make bismuth oxide one of the most perspective candidates for application in optoelectronics, solar cells and solid oxide fuel cells (SOFCs). Bismuth oxide has a few main polymorphic forms that are known as α, β, γ, δ. All polymorphs have different crystal structure and various optical, electrical and mechanical properties. Only two of them, the low temperature monoclinic α-phase and high temperature face-centered cubic δ-phase are stable. The other phases are metastable. Magnetron sputtering is a widespread method because of high deposition rate, dense and highly adhesive films, and possibility of using commercially available large area depositio...

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 ...
