We rely on our computers for many tasks throughout our days. From browsing the internet to crunching numbers in Excel, to creating vibrant Power Point presentations and writing copy, we’re using our laptops to multitask and get our jobs done. And now in these times of COVID-19, many of us are using our laptops to tackle our work from home, or children are using them to attend their classes remotely. We demand our computers to work hard, churning through gigs of data to create videos, play games and more.

And that means many of us find our laptops heating up. Unlike desktop PCs, laptops are much smaller in size, not allowing much room for the internal components to have space for air movement. Thermal stress can cause irreparable damage to your laptop. Persistent overheating can fry the motherboard, video card and other internal components of your laptop. It also can decrease your laptop’s lifespan. Overheating can also make the laptop’s battery lose a charge quickly, and if left untreated, could even cause the battery to explode.

Global Graphene Group has the solution to laptops’ thermal management problem. Our heat spreader thermal films dissipate heat throughout a laptop, or any other consumer electronic device, to keep it cool and operating efficiently and safely.

Our AT1500 thermal film dissipates heat twice as fast as a commonly used graphite sheet. Just a thin layer of our thermal film will help laptops run cooler, extending their lifespan. Your laptop will be more reliable, continuing to work hard just like you. And don’t worry about a potentially exploding laptop battery! Our thermal films keep the heat moving away from the battery, eliminating the chance for a fire to spark.

This thermal management technology isn’t years away – it’s available NOW. G³’s thermal film is a drop-in solution, letting computer manufacturers easily incorporate it into their existing production process. Computer manufacturers can leverage graphene’s thermal management properties now in our thin thermal film solutions, which can be cut and sized to exact measurements needed for each laptop model. Our thermal films will keep your laptop cool while you put it to work.

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.

Thermal Management Webinar On Demand

Cell phones, laptops, EV car batteries and more can heat up fast! Heat dissipation is a challenge for manufacturers of consumer electronics, cars and other goods. Graphene is the key to keeping these products cool with its high thermal conductivity.

Our team of experts at Global Graphene Group have developed a portfolio of thermal management products to help companies keep heat under control:

G³ is passionate about graphene and its applications. Graphene’s ability to dissipate heat is a key advantage to add to today’s commercial electronics, automotive, batteries, and more. G³‘s Dr. Matthew Wang and Nathan Holliday presented a recent webinar on graphene’s thermal management applications. Watch G³‘s on demand webinar here. You can download the slides from the webinar here.

Talk with our experts today and learn how graphene can handle your product’s thermal management needs.

Next Generation Graphene Technology – Today

“The sample (Graphene/Sulfur Composite) is the best one we have ever tested.”

“(We’ve) tried other graphene suppliers and found that G³ is the only supplier that offers single layer graphene oxide that works best for their application.”

Graphene is known as the “wonder material,” and major OEMs are turning to Global Graphene Group (G³) to help them improve their product offering. From EV battery solutions to thermal management products, graphene can improve automobiles performance and durability.

G³ knows graphene – our co-founder, Dr. Bor Jang, filed the first patent on graphene in 2002. We’re the market leader in mass producing graphene and graphene-enhanced products. And we’ve worked with many of the major OEM’s to solve their energy storage and thermal management problems. Automotive manufacturers are teed up to leverage graphene’s benefits.

A challenge for OEMs is EV battery capabilities. Current EV batteries are expensive, and limited in their mileage per charge, their energy density, their battery life, their safety and their recharge time. For example, a major EV passenger car has a battery pack with ~250 Wh/kg of energy density, takes over 30 minutes to charge just to 80% and costs about $120/kWh.

G³’s EV battery solutions can solve these problems:

Drive for 1,000 km on one charge
Run for 1 million km without replacing batteries
Resistant to fire/explosion hazards
Recharge within 5-15 minutes
Low-cost (< $100/kWh)

“Our EV products are truly game changers,” said Dr. Aruna Zhamu, President of Honeycomb Battery Company, a subsidiary of G³. “We can help EV vehicles stay on the road longer, make them more affordable and make sure they’re safe.”

Another area OEMs are focused on is heat management. G³’s thermal heat spreaders are drop-in solutions made of single layer graphene and are highly engineered to achieve a variety of thickness needs for different applications, like display screens. They’re easy to handle and die cut into many shapes, making them a nice replacement of thermal paste product to avoid messiness and improve process convenience. Durable and stable, our heat spreaders are long-lasting at temperature range of -40 to 400^oC.

Graphene thermal coating material has many beneficial characteristics: high temperature resistance, fast rate of heat spreading, high thermal conductivity, high heat radiation, insulation, corrosion resistance, and resistance to strong acids and alkalis. G³‘s graphene thermal coatings are specifically designed for use with radiant, bulk heat source. And, with its adhesion and processing properties, G³’s thermal coatings are suitable for a wide range of applications.

G³has developed a series of graphene-based composites for heat dissipation purposes. Sample testing trends show both tensile strength and thermal conductivity are improved as the concentration of graphene in the composite increases. It is a perfect solution for casing applications to housing power modules and battery packs. G³ prepares masterbatches for customers with maximum graphene concentration.

“Our graphene-enhanced thermal solutions have so many applications for OEMs,” said Adam Quirk, President of Taiwan Graphene Company, a subsidiary of G³. “It’s amazing what graphene can accomplish. We’re excited to partner with our customers on their next generation products.”
