Application of Thermally Conductive LSR Composite Materials in Electric Vehicle Battery Thermal Management

04/14/2026

Electric vehicle battery systems generate significant heat that requires effective thermal management to maintain performance and safety. Thermally conductive liquid silicone rubber composites incorporating boron nitride or graphene fillers achieve thermal conductivity values exceeding five watts per meter-kelvin while maintaining electrical insulation and environmental protection properties essential for battery pack applications.

Composite formulation optimizes filler loading to maximize thermal conductivity while maintaining processability in standard LSR molding equipment. Dispersion techniques ensure uniform distribution of thermally conductive particles throughout matrix materials. Mechanical properties including tear strength and elongation remain suitable for sealing and protective applications.

Battery pack applications include module encapsulants, cooling plate interfaces, and connector seals that require both thermal conduction and environmental protection. Design flexibility enables custom shapes and thicknesses to accommodate specific thermal management requirements. Installation simplicity reduces assembly time and potential error sources.

Performance validation includes thermal cycling endurance, electrical insulation maintenance, and environmental resistance testing. Quality assurance protocols verify consistent thermal conductivity and mechanical properties throughout production batches. These advanced materials support electric vehicle performance and safety through effective thermal management solutions.
