The Global Graphene Group

Global Graphene Group Adding a Registered Patent Agent to Team

DAYTON, OHIO, November 5, 2019 – Intellectual property is at the core of Global Graphene Group, Inc.’s success as a leader in the graphene industry. Global Graphene Group (G3) drives innovation in graphene manufacturing processes, from filing the first patent on graphene in 2002 to today’s expansive IP portfolio of 430 U.S. patents and 150 international patents and counting. Kurt Jacobs, an Intellectual Property Engineer at G3, recently passed the U.S.P.T.O Registration exam, commonly known as the patent bar. This will enable him to practice in patent cases before the Patent and Trademark Office. The patent bar is a difficult exam, with a pass rate of 47.2% in 2018*. Jacobs will now be able to file and prosecute patent applications, and draft patent applications for the company.

“Global Graphene Group’s R&D scientists average six to ten patent applications filed per month,” says Bob Crouch, G3’s Director of Intellectual Property. “I am excited to have Kurt’s role at G3 expand to handle more of our company’s patent work. Kurt worked very hard to study for this exam, and passing the exam is a great personal accomplishment for him.”

“I have been very fortunate to find these opportunities at G3, being able to work on both the R&D, and IP sides of the business has given me an exciting insight into the forefront of the industry,” says Kurt Jacobs. “It is exciting to have a role in the development and protection of our technology. And it is exciting to see what will happen next.”

Jacobs, a 2017 Ohio State University alumnus, received a Bachelor’s degree in Chemical Engineering before joining Global Graphene Group. He has worked as an engineer at G3 since 2017, developing and scaling a continuous graphene oxide production method, in research and development for graphene applications and working on G3’s silicon anode production. He transitioned to G3’s Intellectual Property team in October 2018.

G3 Welcomes Visit From Engineers’ Club Group

G3 Welcomes Visit From Engineers’ Club Group

Global Graphene Group welcomed 16 members of the Dayton Engineers’ Club’s Barn Gang to our Dayton facilities yesterday afternoon. The Barn Gang is comprised of retired engineers, and they meet regularly to tour area companies. G3’s John Davis, Dr. Aruna Zhamu and Stuart Blair presented to the group about what graphene is, it’s trajectory in commercialization and Global Graphene Group at a high level.

The Barn Gang was full of great questions and were very interested in graphene’s potential applications. The group toured our thermal labs and discussed our thermal film production both here in Dayton and in Taiwan. The group learned about our graphene-silicon anode production and our plans to increase it in 2020.

G3’s experts discussed our masterbatches and composites, showing off the graphene-infused ECD lacrosse heads we produced last year. The group toured our Quality Lab and discussed our recent ISO re-certification. We finished the tour with a walk through our battery prototyping center and 3,000 square feet of dry rooms.

“Global Graphene Group was proud to host the Engineers’ Club Barn Gang,” said Dr. Aruna Zhamu, G3 co-founder. “Considering Dayton’s history of innovation in engineering, the Barn Gang was very interested in graphene’s applications and how it will change the world.”

“We were excited to welcome the Barn Gang to our Dayton facilities,” said John Davis, G3 COO. “Today’s tour is a great example of sharing the story of graphene and our company with the Dayton area. We are committed to expanding in the Dayton region as we continue to ramp up our commercial production.”

Leading Graphene Innovator Sees Graphene Market at a Tipping Point

The Global Graphene Group (G3) has a 17-year relationship with graphene since Dr. Bor Jang, cofounder of Nanotek Instruments, Inc., discovered graphene in 2002.

Today, the G3 organization currently consists of three groupings of companies. First, there is Nanotek Instruments that holds the over three hundred patents the company has filed since its inception in 1997.

Another of the three branches involves graphene production and this branch includes Angstron Materials Group and Taiwan Graphene Company. Angstron Materials is involved in producing graphene intermediates and thermal interface materials. Taiwan Graphene Company produces graphene oxide and graphene powder.

The third branch of the corporate structure of G3 involves the company’s energy storage interests. This includes two companies: Honeycomb Battery Company and Angstron Energy Company. Angstron Energy produces both a high-energy silicon anode and a graphene-enabled cathode. Honeycomb Battery is focused on producing lithium-sulfur batteries, non-flammable electrolytes and next-generation lithium battery technologies.

G3 recently became a member of The Graphene Council and we took the opportunity to talk to the company’s representatives, including Dr. Jang. Here is our discussion.

Q: The Global Graphene Group (G3) has an interesting pedigree, being a holding company for Angstron Materials, Nanotek Instruments and Honeycomb Battery. Could you provide a bit of background of how the company came to be and how the various companies that make it up create an overall strategy for the commercialization of graphene?

A: In order to properly answer this question, we would like to tell a brief story about a 17-year relationship with graphene.

Dr. Bor Jang founded Nanotek Instruments Inc. in 1997 and over the past two decades, researchers at Nanotek have developed a broad array of nanomaterials and energy storage and conversion technologies.

A significant accomplishment of Nanotek researchers is the fact that Dr. Jang’s research team discovered/invented graphene in 2002, two years before Drs. A. Geim and K. Novoselov published their first paper on graphene in 2004 [Science 306, 666–669 (October 2004)]. Drs. Geim and Novoselov won the 2010 Nobel Physics Prize for their work on graphene.

There is no doubt that Drs. Geim and Novoselov have made highly significant contributions to graphene science and, as such, well-deserve this Nobel Prize. However, it is important for Graphene Council’s members and associates to recognize that Nanotek researchers had submitted three (3) US patent applications and delivered a lecture on graphene before October 2004 when that milestone paper was published. This fact is evidenced in the following:

  • B. Z. Jang and W. C. Huang, “Nano-scaled Graphene Plates,” US Patent Application No. 10/274,473 (submitted on 10/21/2002); now U.S. Pat. No. 7,071,258 (issued 07/04/2006).
  • B. Z. Jang, et al. “Process for Producing Nano-scaled Graphene Plates,” U.S. Patent Application No. 10/858,814 (06/03/2004).
  • Bor Z. Jang, “Nanocomposite compositions for hydrogen storage and methods for supplying hydrogen to fuel cells,” US Pat. Appl. No. 10/910,521 (08/03/2004); now US Pat. No. 7,186,474 (03/06/2007).
  • W. Schwalm, M. Schwalm, and B. Z. Jang, “Local Density of States for Nanoscale Graphene Fragments,” Am. Phy. Soc. Paper No. C1.157, 03/2004, Montreal, Canada.

(In March 2004, Dr. Jang and his colleagues (Drs. W. Schwalm, M. Schwalm, and J. Wagner) presented a paper at the American Physical Society’s Annual Meeting in Montreal, Canada that discussed the density of state function and related electronic properties of graphene.)

Contrary to the common misconception in the graphene space that the liquid phase exfoliation method was developed in 2008 by a Dublin College team (Hernandez, Y. et al. “High-yield production of graphene by liquid-phase exfoliation of graphite,” Nature Nanotechnology, 3, 563–568 (2008)), Dr. Zhamu/Dr. Jang’s research team at Nanotek developed this method and filed a patent application in 2007.

This provides an effective way of producing pristine graphene directly from graphite without chemical intercalation or oxidation [A. Zhamu, et al., “Method of Producing Exfoliated Graphite, Flexible Graphite, and Nano-Scaled Graphene Plates,” US Patent Application No. 11/800,728 (05/08/2007); now US Patent No. 7,824,651 (11/02/2010)].

Between 2002 and 2007, the Nanotek teams also developed other important graphene production processes, including chemical oxidation, supercritical fluid exfoliation, and electrochemical exfoliation.

Supported by significant IP on several different graphene production processes and graphene applications in composites, thermal management, supercapacitor, and batteries, etc., Drs. Zhamu and Jang decided to co-found Angstron Materials, Inc. in 2007 to begin to scale-up of selected graphene production processes and certain graphene application products.

Subsequently, after many years of development, prototyping, and mass production efforts and establishment of a vast IP portfolio, we found the timing was right for us to establish several business units for more effective commercialization of vastly different products for different industries.

Taiwan Graphene Company (TGC) was founded in 2015 as a leading producer of single-layer graphene oxide, graphene-based nano-intermediates and non-energy-focused application products. Angstron Energy Company (AEC) was founded in 2015 as producer of lithium battery anode and cathode materials. Honeycomb Battery Company (HBC) was also founded in 2015 as a developer and producer of next-generation safe and long-lasting lithium metal batteries, including quasi-solid state battery, lithium-sulfur battery, and lithium-air battery. Angstron Materials was assigned as a research and development company for development of new processes and products. Nanotek remains as the IP-holding company. As suggested by our investors, we also decided to position all five organizations under one umbrella – Global Graphene Group (G3).

Q: How are you marketing graphene at this point, i.e. are you selling graphene raw materials, master batches, etc.? Or are you developing products that incorporate graphene, specifically for Li-ion batteries? Are there other applications you’re pursuing in addition to energy storage?

A: Our Taiwan Graphene Co. (TGC) is selling graphene in powder and dispersion forms, masterbatches for composites, thermal management products, etc. Angstron Energy Co. (AEC) is selling graphene-enabled Si anode materials and graphene-enhanced cathode materials for the lithium-ion battery industry. Honeycomb Battery Company (HBC) is poised to commercialize lithium metal protection technology, non-flammable electrolytes, graphene-enabled sulfur and selenium cathodes, and graphene-enhanced current collectors for next-generation lithium batteries.

Q: What production methods do you use to make your graphene? How has this production avenue determined the applications for your material?

A: We use a combination of improved chemical oxidation process, liquid phase exfoliation, and other proprietary processes, which G3 invented. We have found that different applications require the use of different graphene types produced by different processes.

Q: What have you discovered to be the biggest challenges for your commercialization of graphene and how have you overcome them?

A: We see the greatest challenge to commercialization that it takes time to qualify the application of graphene into various products. We have relationships with several large OEMs in different markets working with our graphene. It just takes time to go through the qualification process.

Q: What direction do you see for the company in the future? Do you see the company moving further up the value chain to the point where all your graphene production is used internally?

A: The future is to grow. We’re targeting to reach $600m+ in annual sales within the next five years between the combination of products in our value chain and graphene raw materials.

Q: What do you think we can expect in the commercialization of graphene over the next 5 to 10 years?

A: Several major applications (so-called killer applications) of graphene are expected to emerge soon. We will see exponential growth as customers integrate graphene into their products to a point where large expansions of graphene manufacturing are necessary. The challenge will be keeping up with the demand.

G3’s Graphene-enhanced Heat Spreaders Outperform PGS for Thermal Management

Graphene is a two-dimensional nanomaterial with the highest thermal conductivity value* among all known materials. G3’s heat spreader, AT1500, offers a significant performance improvements over current heat spreading products such as PGS (Pyrolytic Graphite Sheet). Our IP-protected single-layer graphene technology enables us to produce a range of thicknesses from 20um-100um for different heat dissipation requirements. This range can also maximize your heat conduction flux capacity in confined and limited spaces.By controlling the alignment and orientation in the x-y direction of each graphene layer, AT1500 guarantees the highest in-plane thermal conductivity.** The thickness advantage of AT1500 cannot be reproduced by current PGS manufactures, which are limited to <40um. Even beyond 100um, G3 can precisely tailor the heat spreader thickness to meet your design expectations while still maintaining the highest thermal conductivity

In fact, our AT1500 at a thickness of 40um has out-performed PGS manufacturers at the same thickness and with bigger temperature drop and better temperature uniformity.

G3 now has roll-to-roll manufacturing capabilities to manufacture 60k sqm/year of freestanding and/or PET backed AT1500.

Cutting-edge Technology for a Classic Sport

For many, the change of seasons isn’t just about weather and longer days, but a change in sports. One of our favorites at G3 is lacrosse, with teams from high school to major league kicking off in the spring. G3 recently teamed with @ECDLacrosse in the development of material for their Rebel +Graphene heads, which were released in a limited edition.

Graphene’s properties, including its light weight and impact resistance, are featured in the customized composite of G3’s graphene with ECD’s polymer. The resulting Rebel +Graphene lacrosse heads exhibit increased impact strength, increased stiffness, and no perceptible additional weight.

We look forward to seeing the lab-tested results play out in on the field in the upcoming season!
