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

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:

  1. Liquid electrolyte-lithium metal reactions
  2. Lithium dendrite-induced internal shorting and formation of inactive lithium particles
  3. 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.

Global Graphene Group Awarded Patent on Elastic Anode Battery Materials

DAYTON, OH, September 30, 2020 – Global Graphene Group (G3), a Dayton, Ohio-based materials science company, was recently awarded a US Patent that is in-line with leading EV OEM technical solution roadmaps. G3’s patent for its elastomer-encapsulated particles of high-capacity anode active materials for lithium batteries (US Patent No. 10,734,642 (08/04/2020)) covers essentially any high-elasticity and ion-conducting polymer for lithium-ion battery anode applications.

G3 plans to capitalize on the explosive growth in EV battery development and is expanding production of its silicon-based anode materials.

G3’s expansion supports the industry’s need for better battery solutions recently discussed by a leading EV OEM. G3’s focus on silicon anodes will drive significant improvements in lithium-ion batteries. Industry-leading EV OEMs indicate elastic and ion-conducting polymer-encapsulated Si technology will be needed to drive EV battery technology that will lower cost and provide higher energy density, extending the EV driving range by 20%. G3’s innovative Si anodes can deliver this and more today as a drop-in technology. Furthermore, G3’s entire suite of battery-enabling technologies can deliver driving range improvements of 50-100% at significant cost savings.

G3 has developed the anode materials that precisely meet battery requirements for next-generation EV batteries as outlined by the industry. G3 is actively seeking to establish partnerships for expanding manufacturing capacity of its advanced anode materials.

Leading EV OEMs are focusing on silicon anodes that have the following features:

  • Low-cost Si particles
  • Elastic, ion-conducting polymer coating on these Si particles
  • Highly elastic binder used in the anode to maintain electrode structural integrity.

“G3’s Si-anode technology meet these criteria,” said Dr. Bor Jang, G3 CEO and co-founder. “Recent announcements by EV OEM’s validate that G3’s Si-anode solutions will be a key enabler for next-generation EV batteries. Our team is excited that the EV industry is focused on the same critical path as we see as foundational using Si-anode improving EV batteries.”

“Electric vehicles will continue to grow global market share over the next decade,” said Adam Quirk, G3 VP of Business Development. “Our EV battery technology, including Si-anode, are very attractive to EV manufacturers. It’s a drop-in solution that can easily be incorporated into existing manufacturing processes. We are engaged with many top-tier OEMs who are now validating our solutions.”

G3 is holding a free webinar on Thursday, October 8 at 2 p.m. Eastern to discuss this and other battery technologies for EVs and the direction of the EV battery market. Registration is open for the webinar online: https://bit.ly/3jfI1D0.

Recently, industry leaders stated that the anode material cost could be dropped to $1.20 a kilowatt hour by using new surface stabilization and elastic binder approaches (88% reduction in the anode material cost). G3’s innovative solutions start with silicon and stabilize it with an elastic, ion-conducting polymer that integrates into the electrode with an elastic binder. G3 has the most significant intellectual properties (IPs) in high-capacity anode materials with 80+ US patents (issued or pending), 35 of which are specifically directed at elastic ion-conducting polymer coatings and binders.

The most commonly used material for lithium-ion batteries today is graphite. However, graphite can only store lithium up to 372 mAh/g during a battery charge. In contrast, Si can store lithium up to an amount of 4200 mAh/g), significantly increasing energy density.
