Angstron Materials // New Graphene Application / Nanotek Gets $1m

ongoing development of touch screens for consu- mer electronics is driving a growing need for sense data. Angstron’s graphene material is being used by a major manufacturer which produces actuator and sensing components for this market. The world’s largest producer of nano graphene platelets (NGPs), Angstron’s single layer graphene has exhibited the highest electrical properties including exceptional in-plane electrical conductivity (up to ~20,000 S/cm) when compared to other nanomaterials including carbon nano-tubes (CNTs) and carbon nano-fibers (CNFs).

Furthermore, Angstron Materials Inc., has invented a graphene-based supercapacitor with ultra high energy density, a feature that permits storage of a significant amount of energy. As a rechargeable en- ergy storage device, supercapacitors can be charged and discharged more quickly than batteries but have been challenged by their inability to store energy in the amounts required by automotive and electronic applications. Angstron’s graphene-based supercapaci- tor has demonstrated an energy density that exceeds that of commercially available supercapacitors and is comparable with nickel metal hydride batteries.

“A supercapacitor that can store this much energy yet be completely charged or discharged in seconds

ngstron Materials Inc., announced the world’s first commercial graphene application. The

or minutes offers a number of promising applications for the automotive and electronics industries,” said Dr. Bor Jang, co-founder of Angstron. “This type of supercapacitor is especially attractive for electric ve- hicle applications where the pairing of supercapaci- tors with fuel cells or batteries could provide a hybrid system capable of delivering high power acceleration and energy recovery during braking.”

Angstron Materials offers a variety of graphene mate- rials in sizes ranging from nano to micron in the x, y and z axis. These advanced materials are collectively referred to as nano graphene platelets (NGPs).

Anymore, The Ohio Third Frontier Commission awarded Nanotek Instruments Inc. $1 million to accelerate commercialization of its nano graphene platelets-based electrode materials for next generati- on supercapacitors. Nanotek’s NGP electrode tech- nology offers the energy density of a modern bat- tery yet can be recharged in less than two minutes. Nanotek will team with its manufacturing arm Ang- stron Materials Inc. on the project which promises to provide a breakthrough step in energy storage. “The commercialization of supercapacitor techno- logy is crucial not only to advancing the transition
