Goodbye 2020 – We’re Excited for 2021!

This year has not turned out the way most everyone imagined it would from the start. No one could have predicted that we’d be in the middle of a worldwide pandemic. Despite the challenges that 2020 presented, the team at Global Graphene Group is ending 2020 on a high note. Graphene is part of the global conversation now more than ever before. And G3 is prepared to provide our solutions and technology to help improve lives.

To help fight the global pandemic, G3 is currently working with a company to produce PPE masks using our graphene solutions. Graphene is known for its anti-microbial and anti-viral properties. Researchers have incorporated graphene into N-95 masks, essential PPE for healthcare workers and others. This added layer of protection has shown to provide up to 99% effectiveness at blocking the COVID-19 virus.

G3 continues to work with a leading Fortune 75 company to incorporate graphene into their products. G3’s graphene oxide dispersion has shown to improve nylon tensile strength by as much as 400% in the similar markets. We’re looking forward to commercializing our efforts with this company in 2021.

G3 is also working on our graphene-enhanced coatings for several key industries. Adding a small weight percentage of graphene to paints and coatings can reduce the amount of material needed to coat a structure by more than 40%, while adding significant anti-corrosion properties. This will decrease the costs of coatings for companies and extend the life of the coating.

Many areas of the world have pushed for EV adoption in the next few years, making EV OEMs look for ways to increase battery energy density and safety, ramp up the mileage per charge and decrease production costs. One top-tier OEM announced its intention to use a specific anode technology using elastic polymers, which G3 owns the IP for.

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 is working with several top-tier EV OEMs to validate our EV battery solutions and we look to increase production of our Si anode solution in 2021.

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.

The Quest for the Million Mile EV Battery is Heating Up

Today is Tesla’s first annual Battery Day. It’s a day to focus on EV technology and what’s next in advancing it towards widespread consumer adoption. We’ve been focusing on how to maximize today’s EV batteries to make them high density, quick charge, affordable and safe for years. At Global Graphene Group, we know that EVs are the future, and our drop-in graphene-enhanced solutions can help EV manufacturers improve their battery function, today.

Elon Musk, Tesla’s CEO, tweeted yesterday that today’s Battery Day announcements will include news on long-term manufacturing of EV’s, including semis, cybertrucks and a roadster.

A leak surfaced recently that a larger cell will be announced during today’s Battery Day. The rumored 4070 cell would be used in batteries for electric semi and cybertrucks. No matter which size the battery cell will be, the heat dissipation will be a more serious problem than the current 2170 cell because heat will need to travel at least twice the distance from the core of the cell.

Heat can be a big spoiler for the EV batteries companies like Tesla are banking on. Heat builds up when batteries are super charged and under continuous driving conditions. That’s exactly what online leaks suggest Tesla has planned with batteries for semi and cybertrucks. While it makes sense to prioritize these types of vehicles in terms of their environmental impact, having delivery trucks and freight carriers with massive batteries driving continuously add up to a potential power disaster.

There’s already evidence of EV batteries losing their power density and becoming unsafe in high heat areas – think Arizona, Texas, Nevada and other areas of the country that tend to heat up. In some of these areas, they experience more than five days per year with temperatures climbing over 100°F. Much of the country experiences temperatures above 80°F throughout the summer months. Those high temps can decrease the battery life dramatically. Lithium-ion batteries have a decreased lifespan under high and continuous heat situations. Vehicles that are heavily used throughout the day with little break and ones driving in tropical weather areas are affected.

Specifically, the corrosion reactions between the battery’s electrolyte and the current collector can be very serious above 113°F. And that is why many EV owners observed reduced charging current when their battery pack reached 113°F during fast-charging in order to prevent the damage. Research shows even just parking outside when the ambient temperature is above 90°F can permanently damage the EV battery. E-trucks are supposed to run for hours continuously every day which will damage the battery pack from heat more than passenger EVs.

So how to EV manufacturers mitigate the high heat issues for their batteries? Of course, a nice cooling system can solve this problem, but it also consumes the energy from the battery and thus shortens the mileage per charge. They could adjust the battery’s power during fast charging when the battery temperature hits the upper temperature limit. But some real data showed up to 50% more time will be needed for fast charging in hot climates, which is a negative for consumers. EV owners could park in the shade or avoid driving during hot days, but that’s not always possible.

While many consider solid-state batteries to be the “holy grail” of EV batteries, but they’re still years away from commercialization. At G3, we have developed a portfolio of graphene-enhanced battery solutions that bridge the gap between today’s lithium-ion batteries and tomorrow’s solid-state.

Our graphene-coated current collector performs much better than bare aluminum current collector, even at temperatures above 131° making it a good fit for military applications under extreme conditions. It would also benefit E-trucks and every EV that needs higher power and real fast-charging. The theory behind this is that HF generated from a chain reaction in electrolyte can damage the surface of the current collector in a Li-ion battery. The corrosion reaction will become more serious when temperatures or voltage are high.

G3‘s graphene-coated Al current collector solves this problem. We did an accelerated cycling test at 55°C between 4.0 and 4.3V, the voltage range the corrosion is serious. You can see that when commercial bare Al was used, the capacity dropped rapidly to <80% capacity retention within 50 cycles.

Our graphene-coated Al current collector can last over hundreds of cycles. 55°C might be considered as an extreme condition but actually the battery can reach this temperature fairly easily. Super-charging, parking under direct sunlight in summer or tropical areas, or continuously driving for hours will let the battery heat to over this temperature and damage the battery permanently. In the future, we will use this product in our cells to improve the cycle life, making it capable of high-power charge/discharge, and giving consumers worry-free parking for days of hot weather. Tesla and other EV OEMs can surely benefit from our graphene-coated current collector.

We’re ready to talk about our EV battery technology. Give us a call at 937-331-9884 or email [email protected] to schedule a time. Our drop-in solutions are ready now and will lower EV battery costs, increase their range and provide a safer battery. Widespread EV adoption is around the corner, and G3 is prepared to be part of the EV revolution.

EV Adoption is Sooner than You Think

Years ago, Hanna-Barbera would have us think that we’d be living in 2020 driving flying cars. George Jetson zipped off to Spacely Sprockets for work in his flying car and made the idea of crazy advanced transportation being accessible to everyday people seem possible. All these years later, we’re still driving our gas guzzlers, but there are electric vehicles on the roads today. (Yes, we don’t have flying cars, yet…)

Electric vehicles are still in their early stages of adoption, especially in the US. 2019 EV sales in the US totaled 330,000. However, US EV sales account for only 2.2% market share. There is still major room for growth in the automotive sector for electric vehicles.

There are several factors for why EV’s have been slow to take off:

  • EV’s are expensive.
  • EV battery’s take long to recharge.
  • EV battery’s pose safety risks, with many accounts of EV’s catching fire.

Our Global Graphene Group headquarters of Dayton, Ohio, USA, is a Midwestern city known for its extraordinary innovation history. (Everyone has heard of the founders of flight, the Wright Brothers, right?) We have a population of around 800,000 in the metro area. We are situated along several large interstate highways, with gas stations always nearby. There are 82 charging stations in a 15 km radius of Dayton. That’s a far cry from the hundreds of traditional gas stations dotted around the region. Seventy-nine percent of the EV charging stations are free to use. Most charging stations have one or two available slots, meaning you may be forced to wait your turn to charge up your car. We’re used to quickly fueling up and going on our way. Who has time to wait 30 or more minutes to recharge their car?

Electric vehicles are the future and graphene helps that future become a reality now. Global Graphene Group’s experts have developed and tested graphene-enabled battery technology that is proven to allow EVs to:

  • Run for 1 million miles without replacing the battery
  • Drive for more than 500 miles on a single charge
  • Cost 40% less than current EV batteries
  • Recharge in 2-6 minutes
  • Be 100% safe from flammability problems

With G3’s innovative battery solutions, EVs will become less expensive. Consumers will trust that their electric vehicle won’t catch fire in their garage while recharging. Longer road trips will be possible without the need to find an out of the way charging station as your EV will able to go further on a single charge. Suddenly, an electric vehicle becomes transportation that people can easily fit into their lifestyle. And that’s when EVs will be more adopted and explode in popularity. Graphene is the key to making electric vehicles safer, cost-effective and more sustainable.
