▎ 摘　　要

NOVELTY - The flexible heat transfer material (1) comprises a matrix and a filler. The thermal conductivity of the filler is greater than the thermal conductivity of the matrix. The heat transfer material forms a unit of an inflatable thermal management duct (11). The duct is located within a battery pack (10) that has multiple cells. The unit of the duct is in contact with the surface of one cell. The duct is inflated such that a unit of the duct conforms to a unit of the surface shape of at least one cell. The matrix comprises low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), or high-density polyethylene (HDPE). The filler (3) has carbon, carbon black, graphite, graphene, multi-walled carbon nanotubes, or single-wall carbon nanotubes. The filler has aluminum oxide, silicon carbide, boron nitride, silicon nitrate, alumina, aluminum nitride, or zinc oxide. USE - Flexible heat transfer material for thermally contacting one cell within a battery pack. ADVANTAGE - The flexible heat transfer material increases thermal conductivity and maintains a low electrical conductivity and has the flexibility of the material and prevents the duct from over-inflating and bursting. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of forming a flexible heat transfer material for thermally contacting one cell within a battery pack. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic sectional view of a heat transfer material.
