Phase Change Composite (PCC™) Thermal Management Material

When lithium-ion batteries get too hot, three bad things happen: cycle life decreases, battery performance decreases, and risk of a battery fire increases.

AllCell’s PCC composite thermal material absorbs and distribute heat to mitigate the negative impacts.

Lithium-ion cells in the battery pack are placed in direct contact with our PCC. The material spreads the heat evenly throughout the pack, avoiding hot spots and ensuring temperature uniformity. Thermal energy is absorbed by an internal melting process rather than continuing to raise the temperature. More details on the PCC™ technology can be found here.

AllCell produces several standard versions of the PCC™ material available for purchase for battery and non-battery applications (see data sheet here), and customized versions can be designed with different thermal, mechanical, and electrical properties.
