Transportation

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. 

Automotive Batteries

Automotive Batteries

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.

Marine Batteries

Marine Batteries

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

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.
