The latest Global Graphene Group (G3) news:

Global Graphene Group launches a graphene-silicon Li-Ion battery anode material

Global Graphene Group, and its subsidiary Angstron Energy (AEC) has developed a new graphene/silicon composite anode material (GCA-II-N) which can increase the capacity of Li-Ion batteries while reducing the battery's size and weight. AEC current market focus is on electronic bikes and consumer electronics, but is also working with Tier-1 electric cars and trucks makers.

Global Graphene Group graphene-silicon anode material
AEC tells us that by wrapping single-layer graphene (or r-GO) around silicon nanoparticles, the volume expansion/contraction of the Silicon during the battery's charge/discharge cycle can be cushioned by the flexibility and mechanical strength of the graphene. The graphene sheets also form a 3D conductive network which ensures good electrical contacts between the Silicon particles and the current collector.

G3 launches G3-Fireshield Technology, a graphene-based line of components for the reduction of battery fires

Global Graphene Group (G3), the holding company of Angstron Materials and Nanotek Instruments, has announced G3-Fireshield Technology – a suite of next generation battery components to dramatically reduce the risk of fire occurrences in EVs, portable electronics, and a range of other devices.

G3 states that this breakthrough is the first of its kind to overcome the intrinsic flammability problems associated with multiple battery material components. G3 explains that a conventional Li-ion battery is made up of three primary components: a negative electrode, a separator soaked in electrolyte solution, and a positive electrode. At elevated temperatures, brought on by mechanical, electrical or thermal abuse, each of these components undergoes chemical and/or structural changes that release energy from the cell in harmful ways.

G3 and Lanka Graphite enter agreement to develop graphene-enhanced products

Global Graphene Group (G3), a holding company for subsidiaries like Angstron Materials, has signed Heads of Agreement with Lanka Graphite, a graphite exploration company. The joint venture entity (LGR 50%, G3 50%) will develop a range of commercial graphene projects.

G3 is reportedly scaling a broad range of commercial platforms of graphene applications in several , areas like energy storage, coatings, and thermal management. Lanka Graphite will supply vein graphite product into the joint venture in addition to assisting with sourcing investment, marketing and administration. G3 proposes to supply its experience in developing IP and research grants, commercialization planning and manufacturing infrastructure.

Experts roundup: on Graphene Oxide for composites

Last month we launched a new feature - Experts Roundup. In this feature we ask graphene professionals to answer a short graphene related question. Last month's question was "will CVD ever be a viable commercial way to produce graphene?" and we got great response to that. Hopefully this month feature will be just as good.

In the growing field of graphene-enhanced composites, especially plastics, how does graphene oxide fit in? Does it have any significant advantages over graphene?

Ian Fuller, VP business development & engineering, Angstron Materials : I would classify graphene oxide as a functionalized graphene nanomaterial. Functionalization, in general, allows for tailored nanomaterials for applications such as polymer nanocomposites. The oxygen-based groups on the surface of graphene oxide often promote coupling between the polymer and the nanomaterial leading to enhanced properties such as strength and quality of dispersion (however, electrical and thermal conductivity are often reduced). Similarly, other functional groups can be added to the surface of a graphene platelet to customize it for a range of applications and polymers.

Angstron Materials' holding company secures $10 million investment

G3 (Global Graphene Group), a holding company for subsidiaries Angstron Materials, Honeycomb Battery and Nanotek Instruments, announced that it has secured the first $10 million of a Preferred Series A investment from Western & Southern Financial Group, with conditions for a second close of an additional $13 million for a total $23 million Series A investment with Western & Southern as the sole investor.

G3 is engaged in commercializing graphene raw materials, and graphene-enabled applications including nanocomposites, thermal interface materials, and advanced batteries. G3 is headquartered in Dayton with operations in Asia.
