Honeycomb Battery Company and Nubia Brand International announce closing of business combination

Last year, Global Graphene Group (G3) announced plans for its subsidiary, Honeycomb Battery, to merge with a SPAC company (Nubia Brand International Corp.) in a deal worth $925 million. Earlier this month, it was announced that this business combination was completed.

Upon the completion of the business combination, the combined company was renamed Solidion Technology. Beginning on Monday, February 5, 2024, Solidion’s common stock was expected to begin trading on the NASDAQ Global Market under the new ticker symbol “STI.”

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.

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) logo imageGlobal 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.

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 sets up new company and reveals plans to revolutionize the graphene market

Angstron Materials has announced the establishment of a sister company called EnerG Nano, that is looking to invest around $20 million to open a production facility in Miamisburg. The company has picked a developer and a site at the Mound campus, but is still working to line up investors and incentives before making a commitment.

It seems that the plan is for Angstron to sell graphene to EnerG Nano, which would use it to make energy storage devices such as lithium-ion batteries. To boost production, Angstron is ramping up for a more than $1 million expansion that would more than double its space, according to an economic grant application. The investment would go toward purchasing a nearby 26,000-square-foot facility as well as renovations and equipment.
