Angstron Materials announced a spin-off company called Angstron Supercapacitor that was formed to produce a new supercapacitor electrode material made from Graphene.

The new material (patented by US patent #7,623,340) is based on nano graphene platelets (NGPs). Angstron developed curved graphene sheets that resist restacking and this dramatically improved surface area and energy density.

Nanotek Instruments was awarded $1 million by the Ohio Third Frontier Commission to accelerate the commercialization of its nano graphene platelets-based electrode materials for next generation supercapacitors. This is a joint project by Nanotek and its manufacturing company Angstron Materials.

Nanotek says that their NGP material has solved the low energy density problem by demonstrating an energy density that exceeds that of commercially available supercapacitors and is comparable with nickel metal hydride batteries.

Angstron Materials announced that its Graphene material is being used by a 'major manufacturer' to produce sensing components for touch screens. The company says that this is the world's first commercial graphene application.

We don't know the exact product yet - and how the Graphene is used in it.

Angstron Materials introduced a new high quality graphene oxide product, available in 0.5% water or solvent dispersion. The new graphene oxide product is available in large quantities and Angstron provides next-day delivery. The material is only 0.34 1.0 nanometers thick and is nearly transparent at visible light wave making the material especially suited to applications for transparent coatings.

Angstron Materials has teamed with K2 Energy Solutions to participate in a Department of Energy (DOE) research project for the development of hybrid nano graphene platelet-based high-capacity anodes for Lithium-ion (Li-ion) batteries. The team will commercialize its new anode technology which has the capability to capture the high charge capacity allowed with silicon over extended charge/discharge life, using a network of highly conductive yet inexpensive nanoscale graphite filaments.

Angstron and K2 will conduct the project over three phases with initial activity focused on demonstrating the commercial and technical viability of new high-energy anode materials. This will include delivering data on anodes capable of initial specific capacities of 650 mAh/g and achieving ~50 full charge/discharge cycles in small laboratory scale cells (50 to 100 mAh) at the 1C rate with less than 20 percent capacity fade. Phase II will target development of process technology for cost-effective production of the optimized Si-coated NGP/CNF blends.

Nanotek Instruments, parent company of Angstron Materials, has been issued a US Patent for its development of a new high-performing class of meso-porous nanocomposites.  The new nanocomposite provides a superior supercapacitor electrode material for uses that include hybrid electric vehicles (EVs), transportation and energy storage. The technology is based on the company’s breakthrough discovery of nano graphene platelets (NGPs). Angstron, the world leader in production of NGPs, will make the nanocomposite material.

Angstron will provide the meso-porous NGP nanocomposites in two forms: NGPs coated with a thin layer of conducting polymer or surface functional groups and NGPs bonded by a conductive binder, coating, or matrix material such as a polymeric carbon. The platelets in these products are comprised of a sheet of graphite plane or multiple sheets of graphite plane with a thickness less than 10 nm and an average length, width, or diameter smaller than 500 nm. The binder or matrix material bonded to the platelets to form the nanocomposite material create a surface area greater than 500 m.sup.2/gm.

Angstron Materials announced that they have been awarded a $1.494 million project to develop processes for mass-producing chemically modified (functionalized) Nano Graphene Platelets (NGP) for a nearly limitless number of applications in the aerospace, energy, defense, automotive and telecommunications markets. Angstron was selected for the award by the U.S. Commerce Department’s National Institute of Standards and Technology (NIST).

Angstron developed NGPs as an alternative to carbon nanotubes, which are difficult to disperse in plastic and often have purity issues—not to mention the cost factor. NGPs have been shown to have striking material properties; among other things, it has the highest intrinsic strength and the highest thermal conductivity of all existing materials as well as exceptional in-plane electrical conductivity (up to ~ 20,000 S/cm)and electron mobility that is 100 times faster than silicon.

Angstron Materials will invest $400,000 in machinery and equipment to expand its manufacturing, with Daytona city to support the expansion with a $100,000 grant from its development fund.

Angstron has developed a new class of nanomaterial referred to as nano graphene platelets,. Angstron’s nano-graphene material is protected by 18 U.S. patents and several international patents, issued and pending.
