Global Graphene Group (G3) – an IP Leader in Solid-State Batteries for Next-Gen Electric Vehicles

About G3:
Global Graphene Group, Inc. (G3) is a Dayton, Ohio, USA-based advanced materials and battery technology company. G3 researchers discovered and patented graphene in 2002, two years before Nobel Physics Prize winners, Drs. A. Geim and K. Novoselov, are credited with their “discovery” of graphene in 2004 [Science 306, 666–669 (2004)]. G3 is focused on commercialization of next-generation EV batteries and its fully-owned subsidiary, Angstron Materials, Inc. (AMI), provides graphene and selected non-battery products.

Currently, G3 has 490+ patents specifically related to advanced batteries and it is ranked at the forefront in IP ownership among all the battery start-ups in the world. G3 was recently recognized as one of the two US leaders in solid-state batteries (Solid-State Li-ion Batteries with Inorganic Solid Electrolytes Patent Landscape 2021 – KnowMade). Based on the data compiled in 2021 by KnowMade, a French IP landscape analyzer, G3 had a total of 41 patent families related to solid-state lithium batteries with inorganic solid electrolytes.

Problems Associated with Current Lithium-ion Batteries:
The EV industry is looking for batteries that can deliver four key features: increased energy density for extended driving range on one battery charge, fire safety, fast charging and lower cost. According to Dr. Bor Z Jang, co-founder and CEO, the battery technologies developed by G3 are aimed at addressing these EV battery challenges. Today’s EV batteries are largely based on lithium-ion cells, wherein each cell is typically composed of an anode (negative electrode), a cathode (positive electrode), a separator that electrically isolates the two electrodes, and a liquid electrolyte that provides a medium through which lithium ions can migrate back and forth between the anode and the cathode. The EV battery issues are directly related to the anode, the cathode, and the electrolyte used.

Anode and Cathode Materials of Current Lithium-ion Batteries:
The incumbent anode material is graphite, which stores lithium ions at a theoretical specific capacity of 372 mAh/g (practically, 340-360 mAh/g). A lithium-ion cell, having a graphite anode and a lithium nickel cobalt manganese oxide cathode (NCM, 175-210 mAh/g), provides a specific energy of typically 220-260 Wh/kg. Alternatively, another common cathode material used is lithium iron phosphate (LFP). However, since LFP has a lower capacity (150-160 mAh/g), the energy density achieved is typically lower than 200 Wh/kg. For perspective, the EV industry is looking for a reliable battery capable of delivering a specific energy of 350-450 Wh/kg.

Replacing Graphite with G3 ’s Silicon-Rich Anode Materials for Improved Energy Density:
By replacing the graphite in an anode with silicon (Si, which has a theoretical specific capacity of 3,580-4,000 mAh/g), one can obtain a cell having the desired energy density of 350-400 Wh/kg. G3 has improved silicon anodes by developing a cost-effective graphene/silicon composite anode material that enables a significantly higher energy density (e.g., a 40% increase in the EV driving range) at a 15% reduction in the cell cost ($/kWh). Graphene has proven to be effective in resolving the battery capacity decay problem caused by repeated volume expansion/shrinkage of silicon. G3 provides silicon-rich high-capacity anode materials (Figure 1 below) that exhibit the highest performance-to-cost ratio and make it possible to significantly extend the EV driving range on one battery charge.

G3 is ready to expand its current production capacity of Si-rich high-capacity anode materials from 25 metric tons/year to thousands of metric tons in 3 years.

Replacing Graphite with G3’s Protected Lithium Metal for Improved Energy Density
Alternatively, graphite may be replaced with lithium metal (Li) in the anode to obtain a lithium metal battery, which is commonly believed to be capable of delivering an energy density in the range of 400-500 Wh/kg, depending upon the cathode material used. However, such a potential benefit does not come without challenges. During the charge-discharge cycles of a lithium metal cell, needle-like growths called “lithium dendrites” can occur in the lithium metal in the anode. These dendrites can penetrate through the separator and reach the cathode side and cause internal shorting, which poses fire and explosion hazards. In addition, repeated reactions between the lithium and the liquid electrolyte will continue to consume both the active lithium ions and the liquid electrolyte, leading to rapid capacity decay. While these technical issues have thus far impeded the practical utilization of lithium metal batteries to replace the conventional lithium-ion batteries for EV applications, G3 has developed several lithium metal protection strategies to address these issues.

Flame-Resistant Electrolytes for Improved Safety
The safety of lithium-ion or lithium metal batteries hinges upon the availability of a non-flammable electrolyte. The liquid electrolytes commonly utilized in current lithium-ion batteries contain a lithium salt dissolved in an organic solvent, which contains volatile molecules that can catch fire. In contrast, solid-state electrolytes, comprising no volatile chemical species, are being developed for both lithium-ion and lithium-metal battery types. Further, solid-state electrolytes, when used as a separator, can significantly reduce or eliminate the lithium dendrite issues. However, solid-state electrolytes bring along other types of challenges to a battery designer, including a higher internal impedance (hence, lower power), lower anode or cathode active material proportion (hence, lower-than-expected energy density), and a higher manufacturing cost. The latter challenge is largely a result of the need to develop a new process and new equipment for producing the solid-state separator and for assembling the required components into a battery cell.

G3 has developed a versatile solid-state electrolyte technology that overcomes the issues commonly associated with the state-of-the-art solid-state electrolytes. G3’s electrolytes (trademarked as FireShield TM , Figure 2 below) are process-friendly and compatible with current lithium-ion cell manufacturing processes. Specifically, G3’s disruptive material process technology will enable all current lithium-ion cell manufacturing facilities to produce solid-state or quasi-solid electrolyte-based safe lithium batteries below) without the need to change existing equipment and facilities. This implies that the lithium-ion battery industry can readily enjoy the benefits of solid-state, lithium metal batteries right away, not having to wait 5-10 years.

G3’s battery technology will provide significant benefits across multiple battery parameters, including capacity, operating life, and safety, while minimizing cost. G3 is also ready to commercialize the graphene-protected lithium metal anode technology, which is essential to the accelerated emergence of a solid-state lithium metal battery industry. Further, the process-friendly electrolytes are also ready to solidify G3’s leadership position in converting the entire lithium battery industry into a quasi-solid and solid-state status.

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.

Lightening Up Ships and Keeping Rust at Bay

We rely on goods and products to be shipped around the world each day. Many of the items you purchase may have come from another country, sending weeks or more at sea on their way to your door.  There are over 50,000 cargo ships around the world. We rely on these ships to bring our goods from other countries, and to ship our products abroad. Keeping the ships in great shape is a priority. And one of the biggest problems that plague ships is corrosion.

Anti-corrosion coatings are key to ships to limit the damage done to ships. Corrosion takes place from the combination of high moisture and salt-laden sea spray, both of which directly attack the steel of the ship’s hull. Cargo ships can take upwards of a few million gallons of paint to properly coat their hull. Parts of the ship above the waterline will generally get three coats while those below get seven. To keep it in perspective, one gallon of paint cover 400 square feet. The layers of paint on the ships add to the ships’ weight, which means it must reduce the onboard weight. And these ships need to be repainted every few years, leading companies to spend billions of dollars per year.

Graphene has amazing anti-corrosion properties. A small amount of graphene added to paint can dramatically increase the ship’s anti-corrosion resistance. And the graphene-enhanced paint can extend the coating’s life, taking the lifespan of the paint and extending it to 10 or more years between coatings. That’s a cost savings in terms of the man hours it takes to recoat a vessel and the amount of paint it needs to purchase. In addition, the graphene-enhanced pain reduces the coating weight by 50-60%, allowing for more equipment to be onboard the ship.

Another plus of using graphene-enhanced paint is a reduction in zinc dust in the paint. Zinc dust is typically used in paints to for anti-corrosion. And zinc dust is a known carcinogen. By replacing the zinc dust with graphene, the paint is safer for people.

Graphene-enhanced coatings allow less paint to be needed for covering ships. It reduces the weight of the coatings and increases its anti-corrosion properties. The graphene-enhanced paint is more sustainable, lasting upwards of 10 years between recoats. And it is safer for people’s health with less zinc dust being added to the paint mixture.
