Volt Carbon Technologies has released test results from the University of Waterloo regarding its expanded graphite foil. The material demonstrated an in-plane thermal conductivity of 219 W/mK and signal attenuation over 99.99%, making it a potential alternative to aluminum for heat management and electromagnetic shielding. These materials are being developed for use in energy storage, conductive composites, and thermal management systems. While the results are promising, the company is still working on scaling production and validating specific commercial use cases.

The thermal conductivity numbers look good on paper, but I want to see how this handles actual cycling in a battery pack. Lab results at 0.189 mm are one thing, but long term durability in a high vibration environment is where these materials usually fail. Does anyone know the projected cost per square meter?

Agreed on the cost. If this is significantly more expensive than aluminum, it stays in the lab. For industrial retrofits, the labor to install specialized shielding often outweighs the performance gain unless the space savings are massive.

Interesting from a supply chain perspective. If they can use dry separation for natural graphite, it might bypass some of the heavier chemical processing requirements that trigger stricter environmental regulations. That could speed up permitting for new production plants.

Basically, Volt Carbon is testing a new graphite foil that moves heat better than aluminum and blocks almost all EMI signals. It is still early stage, so no revenue or timelines yet, but it is a solid technical step for energy storage materials.
