Cathode Materials for Li

A rolled foil (RA-type), made from wrought Cu is generally used for high-energy, high-power applications. Aluminum foils are used as the cathode current collector of secondary Li-ion batteries. Currently, the anode is comprised of a Graphite mixture, while the cathode combines Lithium and other choice metals, and all materials in a battery have a theoretical energy density.

Types of Lithium

Its high specific energy makes Li-cobalt the popular choice for mobile phones, laptops and digital cameras. The battery consists of a cobalt oxide cathode and a graphite carbon anode. The cathode has a layered structure and during discharge, lithium ions move from the anode to the cathode.

Graphite Material Supplier

Synthetic graphite was discovered accidentally in the late 1800's. This high purity, highly crystalline material is used in a variety of applications including friction, foundry, electrical carbons, fuel cell bi-polar plates, coatings, electrolytic processes, corrosion products

Quartz Properties

Type 214 rod has the high purity, elevated temperature characteristics and low coefficient of thermal expansion required for wafer carriers and push rods used in semiconductor wafer processing. The material is available in diameters of 1 to 20 mm. Very tight quality control and special processing of raw materials is used to achieve low levels of trace element contamination.

Carbon Fiber Properties

Natural graphite is extracted from ore [39] and is flake-shaped. However, synthetic graphite is extracted by the complete crystallization of the amorphous carbon under high-temperature treatment of more than 2000 C, up to 2500 C. This graphite has excellent[39]

Oxide Ceramics – Aluminum Oxide (Al2O3)

Alumina or aluminum oxide (Al2O3) in its various levels of purity is used more often than any other advanced ceramic material. CeramTec offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design.

Carbon nanotube

The HiPCO process helps in producing high purity single walled carbon nanotubes in higher quantity. The HiPCO reactor operates at high temperature 900-1100 C and high pressure ~30-50 bar. [79] It uses carbon monoxide as the carbon source and Iron pentacarbonyl or Nickel tetracarbonyl as a catalyst.

Magnetic properties of materials

It's important to realize that the magnetization curves for ferromagnetic materials are all strongly dependant upon purity, heat treatment and other factors. However, two features of this curve are immediately apparent: it really is curved rather than straight (as with non-ferromagnets ) and also that the vertical scale is now in teslas (rather than milliteslas as with Figure MPA ).
