SpreaderShield™ flexible graphite heat spreaders provide lightweight, reliable thermal management for space and aerospace, efficiently dissipating heat from high-power electronics and protecting sensitive components from temperature extremes in orbit or flight. […]Learn More
Next-generation electric vehicles (EV), electric airplanes (ePlane), and marine battery systems require rapid charging, high energy density, safety, and long lifespans. For this, they need thermal-management materials that are thin, lightweight, and durable. These materials must not only cool the cells during harsh charging and operating conditions but also prevent propagation in case of a cell failure. SpreaderShield® flexible graphite is used as cooling fins between the cells of a pack or module. It directly replaces bulky, heavy aluminum fins in these lithium-ion battery packs, where being lightweight, compact, and safe is essential.Learn More
The UAV and eVTOL industries have experienced significant growth over the past decade, driven by advancements in technology and increasing applications across various sectors, including military, agriculture, logistics, surveillance, and entertainment. These advancements have led to improved performance and safety of UAVs and eVTOLs, including the critical battery systems that power these aerial vehicles. The engineers and the R&D team at NeoGraf Solutions, continue to find the best graphite thermal management solutions for this rapidly evolving market. Learn More
An emerging trend over the last two to three years has been to add layers of thermal insulation and flame/gas impingement barriers between the pouch and prismatic format cells in a battery pack to prevent thermal propagation. This passive thermal management solution has been shown to effectively prevent propagation without adding excessive weight to the battery. The obvious downside of this method is that the battery cells are surrounded by insulation, and there is no easy path for the internal heat of the cells to spread to the environment outside of the pack. How do you fix the problems caused by using an insulation-only strategy? It’s simple: Add NeoGraf Solutions’ SpreaderShield™ thin, flexible, and lightweight graphite heat spreader to the battery pack. [...] Learn More
In many early battery-powered electric vehicles, cell temperatures were controlled by aluminum. It was a time-tested thermal management material and it could take on some of the structural duties of the battery pack. Battery pack designers recognized aluminum’s drawbacks and began looking for alternative thermal management materials. To spread the same amount of heat as an aluminum plate, NeoGraf Solutions’ SpreaderShield™ flexible graphite is only half of the thickness and one-third of the weight. […..] Learn More
In order for battery powered transportation to become fully viable in the near future, energy density of the battery pack must increase. The optimal solution is to use large surface area pouch cell batteries packed tightly together to form highly energy dense modules. NeoGraf Solutions’ has produced a new video that shows unique an-isotropic arrangement of the high conductivity graphene layers in their SpreaderShield™ graphite. It illustrates how the material prevents battery hot spots, maintaining allowable temperatures and restricts transferring the heat to adjacent battery cells with the thinnest and lightest form-factor possible.

When it comes to safety in an Electric Vehicle (EV), the most important aspect is controlling the massive amount of energy stored in the battery pack. To help with this, significant advances have been made in cell design and battery management systems (BMS). However, even with these advances, the possibility of a single-cell failure is always present. SpreaderShield™ flexible graphite heat spreaders are often used as the thermal management material in high-performance battery packs where a small and lightweight form factor is desirable.

Over the last fifteen years, most of the common consumer electronic devices have gradually become thinner and lighter. Large screen TV’s, cell phones, laptops, and tablets have all had reductions in size and weight, even though the devices themselves are becoming more powerful. One of the main reasons for this has been the switch to flexible graphite heat spreaders.Learn More
