Angstron Materials

Dr Bor Jang founded the company in 2007 and prior to this he had started Nanotek Instruments in 2002. Dr Bor Jang is a well-known figure in the field of graphene and claims to be the first to file patents on the material. Angstron Materials produces graphene oxide and reduced graphene oxide powdres. Angstron Materials currently has a 20 tonne per year production capacity (by powdre weight). Their production technique is based on oxidization-reduction. Indeed, they sell both graphene oxide and graphene powdres. Recently, they have started moving up the value chain and are developing silicon anode materials for Li-ion batteries. This is because, as Mr Beech puts it, no one is going to get rich from supplying graphene alone.

Surface-mediated cells mean faster battery charging

Nanotek Instruments, Inc., and its subsidiary Angstron Materials, Inc., in Dayton, Ohio, have developed a new approach energy storage devices based on rapidly shuttling large numbers of lithium ions between electrodes with massive graphene surfaces.

New energy storage paradigm could lead to reduced EV charging time

Researchers from Nanotek Instruments, Inc., and its subsidiary Angstron Materials, Inc. have proposed a new principle for energy storage that can be applied to electric vehicles, as published in //Nano Letters//.

Graphene supercapacitor breaks storage record

Researchers in the US have made a graphene-based supercapacitor that can store as much energy per unit mass as nickel metal hydride batteries - but unlike batteries, it can be charged or discharged in just minutes or even seconds. The new device has a specific energy density of 85.6 Wh/kg at room temperature and 136 Wh/kg at 80 °C. These are the highest ever values for "electric double layer" supercapacitors based on carbon nanomaterials.
