Bringing the Thermal Management Methods of Consumer Electronics to Transportation Batteries Using SpreaderShield™ Flexible Graphite

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

High-Performance Graphite Thermal Management Solutions Increase Battery Performance

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.

Thermal Propagation Control Strategies in the Electric Vehicle Industry Using SpreaderShield™ Flexible Graphite

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.

Automotive Transition to EV’s Creates New Challenges and New Opportunities

The EV space is developing at an accelerated rate, and it is critical to create safe and reliable transportation. This development creates challenges and opportunities for OEMs and Tier 1s to smoothly and successfully make the transition to EV. NeoGraf Solutions remains committed to this transition in the transportation industry.Learn More

Flexible Graphite Use in Electric Vehicles

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
