“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 400oC.
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.
G3 has 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.”
