Graphite is leading the transportation revolution. From heat spreaders in batteries, to thermal interface material in LED headlights, to engine gaskets and seals, to fire retardant composites and foams, graphite is changing how we interact with transportation on a daily basis. And NeoGraf is the power behind it, developing new ways to use graphite that every transportation enthusiast would admire.
In both battery electric vehicles (BEVs) and hybrid electric vehicles (HEVs), the battery modules must be safe, lightweight, and compact. Traditional thermal management metals, such as aluminum, result in battery modules that are unacceptably large and heavy. Flexible, natural graphite directly replaces aluminum to cool the cells during regular charge/discharge operation and to prevent propagation in the event of a cell failure. Lightweight and effective graphite additives can assist in reducing or eliminating the risk of a fire.
For commercial marine applications, such as ferry boats and diesel-electric hybrid cargo ships, having battery systems that are safe, reliable, compact, and lightweight is critical. In addition to having expected lifetimes of up to 10 years, these marine systems must be able to pass the rigorous anti-propagation standards set forth by groups such as DNV·GL. Economical natural graphite is used as a direct aluminum replacement in these battery systems to provide propagation control, while maintaining a small footprint and lighter weight.
Drone & Aerospace Batteries
In commercial, package delivery, military, and aerospace Drones / UAV’s, battery thermal management is critical. However, being compact and lightweight is just as important. Traditional thermal management metals, such as aluminum, result in battery modules that are thick and heavy, reducing flying time and carrying capacity. Flexible graphite is used as a direct aluminum replacement in these battery systems to provide the needed battery cooling while maintaining a small footprint and lighter weight.
EV/PHEV Chargers and Power Electronics
Charging Electric Vehicles requires reliable, high-performance thermal management materials. From IGBT / Power modules to Inverters, NeoGraf Solutions’ graphite provides the most efficient thermal interface and heat-spreader solutions. Without compromising reliability for performance, these graphite solutions provide versatility to the most demanding of applications.
Automotive Electronics & LIDAR
LIDAR and dashboard electronics need proper thermal management to operate correctly. Heated and cooled seats, armrests, and steering wheels have proven to be some of the most effective ways to ensure passenger comfort. eGraf® SpreaderShield™ Flexible Graphite Heat Spreaders offer the best performance and cost-effectiveness in electronics design and ownership. Whether for internal combustion engines (ICE) or electric vehicles (EVs), NeoGraf has the broadest range of graphite heat spreaders to address all of these automotive electronics challenges.
Head gaskets, exhaust manifolds and EGR valves are but a few places where GraFoil® flexible graphite are used. By providing automotive gasket suppliers with superior quality and reliability for more than 40 years, GraFoil® flexible graphite has become the preferred material for challenging high-temperature automotive sealing applications.
Automotive & Mass Transit Foams
NeoGraf manufactures GrafGuard® expandable graphite products used in foam seating, headliners and engine/battery compartment barrier walls for automobiles, trains, aircrafts and more. Our intumescent materials can be used alone or synergistically with other chemical and intumescent fire retardant materials to limit fire propagation.
The adoption of LEDs in automotive headlights has been swift and effective. Thermal management is critical to ensure the brightness, uniformity, and life of these headlights. Flexible graphite solutions for both thermal interface and heat spreading help reduce or eliminate active cooling while ensuring long-term reliability, performance, and low total cost of ownership.
