▎ 摘  要

NOVELTY - The thermal interface composite (710,720) has a hydrocarbon matrix material and a predetermined number of graphene particles. The graphene particles are dispersed within the hydrocarbon matrix material including paraffin. The graphene particles are dispersed within the hydrocarbon matrix and include a loading percentage between approximately 1 percent and 20 percent. USE - Thermal interface composite for electronic devices, e.g., batteries (claimed) such as high performance lithium ion batteries. ADVANTAGE - Reduces the temperature rise inside the battery since the thermal management in batteries relies on the latent heat stored in a phase change material as its phase changes over a small temperature range. Improves heat conduction outside of the battery pack which leads to a significant decrease in the temperature rise due to the combination of latent heat storage. Facilitates increased thermal conductivity of the composite by easy attachment of hydrocarbon molecules to graphene flakes at the experimentally determined processing temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method of cooling a battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic sectional view of the system using a thermal interface composite.
