Global Graphene Group Lithium Metal Battery Patents Hold Key to EV Future

11/18/2020 by Amy Maggart Leave a Comment

DAYTON, OHIO, November 18, 2020 – Global Graphene Group (G³) announces the issuance of 8 key patents for long range lithium metal battery technology. This suite of patented solutions is fundamental for EV OEMs to move forward with solid-state or lithium metal battery development, an energy dense battery that will give EVs an extended driving range on a single charge. This technology will enable widespread market adoption of EVs. The patents were approved between May and November of 2020.

There are the four components that make-up a lithium battery: the cathode, anode, separator and the electrolyte. G³’s patented technologies provide not only the precise quantities and quality of ingredients, but also how we combine and prepare them, since not every lithium battery is the same. The make-up of the key raw materials, energy and power density, safety, service life, etc. – all of this has been thoroughly researched, tested and evaluated by our team of subject matter experts.

Specifically, these patents address the three most critical problems in lithium metal batteries:

Liquid electrolyte-lithium metal reactions
Lithium dendrite-induced internal shorting and formation of inactive lithium particles
Large solid electrolyte-electrode gap and high interfacial impedance

These problems can cause safety issues including fire hazards and reduced energy density, lowering the EV battery’s performance and cycle life.

G³ has all the required technologies and expertise to overcome the technical barriers that have so far impeded the emergence of next-generation lithium metal batteries.

“Solid-state lithium metal batteries are the ‘holy grail’ for EV OEMs,” said Dr. Bor Jang, G³ co-founder and CEO. “Current Li-metal batteries have issues with the anode. For instance, when the battery discharges, a gap is created in the anode that downgrades the battery’s performance. G³’s patented elastic polymer-based anode technology creates a protective layer that eliminates this problem. Our patented technology is the leader in anode protective layers for solid state Li-metal batteries.”

“EV OEMs are focused on moving to solid-state Li-metal batteries for the future expansion of the EV market,” said Adam Quirk, G³ VP of Business Development. “Solid-state batteries have a higher energy density, meaning people can drive further on a single charge. But the EV OEMs will need to leverage G³’s lithium metal protection patents to develop safe and high performing solid-state batteries.”

“We’re excited about this technology and working with companies to partner with us to bring this new technology to life for solid-state batteries,” said Quirk.

G³ plans to host a webinar on December 9 to discuss their lithium metal anode protection patents. Registration for the free webinar is available now at https://bit.ly/32V7pbl.

NAI Names Dr. Bor Jang to 2019 Fellows Class

12/12/2019 by The Global Graphene Group Leave a Comment

DAYTON, OHIO, December 12, 2019 – The National Academy of Inventors (NAI) has named Dr. Bor Jang, CEO and Co-founder of Global Graphene Group (G³), a 2019 Fellow. Dr. Jang joins a class of 169 innovators from around the world in this year’s Fellows group.

According to the NAI, “Election to NAI Fellow is the highest professional distinction accorded solely to academic inventors. To date, NAI Fellows hold more than 41,500 issued U.S. patents, which have generated over 11,000 licensed technologies and companies, and created more than 36 million jobs. In addition, over $1.6 trillion in revenue has been generated based on NAI Fellow discoveries.”

Dr. Jang is recognized as the world’s number 1 graphene inventor, writing the first patent on graphene, B. Z. Jang, et al, “Nano-scaled Graphene Plates,” U.S. Pat. Appl. No. 10/274,473 (10/21/2002); now U.S. Pat. No. 7,071,258 (07/04/2006), two years before the Nobel laureates Andre Geim and Konstantin Novoselov published their results on mechanical exfoliation of graphene using Scotch tape. He is an inventor on at least 245 issued U.S. patents, at least 290 pending U.S. patent applications, at least 85 active international (PCT) patent applications, at least 80 more expired international (PCT) patent applications, and many dozens of foreign issued patents and pending patent applications based on those international (PCT) patent applications. The vast majority of these relate to graphene, graphene-related products, batteries, battery components, supercapacitors, and/or fuel cells.

Dr. Jang’s influence on the graphene market is immense. His graphene-enabled innovations have helped lead G³ to become the world’s largest mass producer of single-layer graphene and graphene-enhanced silicon anode.

“It is a sincere honor to be recognized by the National Academy of Inventors,” said Dr. Jang. “I have dedicated my career to driving innovation and continue to focus on bringing new technologies to market to make a difference in the world.”

“We are proud of Dr. Jang’s recognition by the NAI,” said Dr. Aruna Zhamu, Vice President of New Product/Process Development and Co-Founder of Global Graphene Group. “Innovation is a key to our company’s success, and Dr. Jang’s contributions to our scientific team are immeasurable.”

Prior to starting G³, Dr. Jang served as the head of Department of Mechanical Engineering and Applied Mechanics at North Dakota State University from 2002-2005 and was promoted to Dean of College of Engineering and Computer Science at Wright State University from 2005 until 2010 when he retired from academia. He holds a B.S. in Physics from National Central University in Taiwan, and an M.S. and PhD in Materials Science and Engineering from MIT.

Dr. Jang will be inducted into the NAI Fellows Program in a ceremony to be held in Phoenix, Arizona, on April 10, 2020.

Global Graphene Group Adding a Registered Patent Agent to Team

11/05/2019 by The Global Graphene Group Leave a Comment

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.
