5G is Here. Are You Ready?

Consumer electronics, especially cell phones, are a normal part of our daily lives. Most people depend on their cell phone, tablets, laptops and more to manage their work and personal lives. We use these devices to stay connected to our family and friends, now more than ever before. And graphene can give those devices a longer, safer battery life, to keep you connected to what matters most to you.

Have you ever noticed that your electronics tend to heat up with extended use? For example, if you’re talking on your phone long enough, your phone will start to get hot. That’s the battery inside your device working hard. 5G technology will put even more of a strain on your devices since it will enable you to run larger applications with faster speeds. Your poor device battery will overheat fast.

Graphene can eliminate that issue. A thin layer of graphene incorporated into your device’s battery will keep the battery cool. And that will keep your device safe. Take a look at this video we filmed using our graphene-enabled solutions for device batteries. In this video, we put an everyday nail through a lithium-ion battery, typically used in cell phones. The battery quickly ignites. Then we show the same nail penetrating a lithium-ion battery that includes a layer of our FireShield™ electrolyte technology, which does not ignite the battery. FireShield makes the battery safe.

Our graphene-enabled battery solutions also work to extend the battery life of your devices, and allow them to quickly recharge. Goodbye waiting around for your cell phone to recharge! Quick recharge times mean less electricity is used to charge your devices, helping the environment. Our solutions make your devices more user friendly, and so much safer.

Let’s talk about our graphene-enabled battery solutions and how we can improve consumer electronics.

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.

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.

Graphene Gets You Airborne Faster

Have you ever flown in the middle of winter? If you live in or have traveled to areas where snow and ice are the norm during the winter months, you’ve probably spent some time sitting in your seat on an airplane, waiting possibly hours for the plane to be de-iced and ready to take flight. It’s a pain for you, the traveler, and a major pain for the airlines, as it keeps planes on the ground longer and uses chemicals to defrost the plane.

Global Graphene Group is headquartered in Dayton, Ohio, the birthplace of aviation. The Wright Brothers built their first airplane and tested it in Dayton. We’re very proud of our aviation heritage. And graphene can have a positive impact on the aerospace industry and the environment. At G3, our team of experts have created thermal films with graphene that can sustainably de-ice airplane windows and wings. Currently, airlines use harsh chemicals and hardware that can go haywire to de-ice. It can take up to an hour and a half to de-ice a typical 747. More extensive snow and ice may involve a truck to spray the plane down with chemicals, which costs more and takes longer. But by adding a thin layer of our graphene-infused thermal film to an airplane’s windows and wings, planes can leverage graphene’s inherent electric conductivity to heat up the windows and wings of the plane. Airplanes will be able to take off in no time, and passengers will be getting where they need to go sooner.

Our thermal film, when added to airplanes, removes the need for chemicals to be used to de-ice the plane. The film keeps those chemicals from running off into our water streams, negatively impacting the environment. Our thermal film also lowers the cost of maintenance on planes by eliminating the hardware needed to manage the chemicals they currently use to de-ice. Airlines are able to de-ice their planes quickly, dramatically decreasing the downtime they currently use.

Challenge: Build a Structure Using Half the Material.

Have you ever been asked to do more with less? It seems like we’re asked to do more and more with fewer and fewer resources. Use less money, less time, less materials. It’s a difficult task to achieve, especially when thinking in terms of how your actions impact the environment.

When we look at the biggest offenders to the environment in terms of carbon dioxide (CO2) emissions, concrete is towards the top of the list. Everything from creating the concrete, transporting it and the amount needed to build a structure – it’s all a LOT!  Concrete is second only to water as the most-consumer resource on Earth. Concrete is the source of about 8% of the world’s CO2 emissions.

We can’t get away from using concrete. It’s an affordable building material that delivers structural strength and durability. Most buildings are made from it. What we CAN do to help lessen concrete’s environmental impact is make it more responsibly.

Not to mention the regulatory aspect of using concrete… According to this Forbes article, “Under a business-as-usual scenario, the cement company could expect to emit 120 units of GHGs. In the long-term, the goal is for the manufacturer to find ways of producing cement without emitting as many GHGs; to meet its regulatory burden in the short-term, it will need to buy carbon offsets to bring its emissions down to its mandate of 100 units.”  Companies need ways to decrease the amount of carbon emissions used in their buildings to earn carbon credits.

Enter graphene.

Adding a small amount of graphene into concrete allows for a 33%+ reduction of material needed for the same load bearing structure. This reduces the amount of CO2 during formation and all the associated transportation. The installation and curing times required are shortened, significantly reducing CO2. Installation and logistics costs are decreased.

Graphene-infused concrete lowers the amount of concrete needed while making the building stronger and more durable. This gives companies more carbon credits for using less material in their structure. Graphene-infused concrete is four times more water resistant and twice as strong as concrete alone.

Reinforce graphene concrete is more environmentally friendly and sustainable. It lowers the amount of maintenance needed on the structure in the long-term, ultimately saving money. It’s a win-win for the company and the environment.
