Event Details


The battery lifetime, the performance of charge and discharge and the thermal Runaway safety risk are some of the concerns that Thermal Interface Material (TIM) can address. To achieve an efficient thermal management during the vehicle operating life, a high thermal conductivity value is not sufficient, material properties as (1) adhesion strength, (2) coefficient of thermal expansion and (3) elastomeric modulus will secure the interface contact which is critical to reduce the interfacial thermal resistivity and maintain a stable heat flow during the battery pack lifetime. The change from the modular design (cell to pack) to structural pack design (cell to chassis) is addressed in the Webinar to highlight the importance of the design on the material selection. Indeed, the original design has seen a large adoption of Gap filler as TIM, the new design sees a shift to adhesive TIM. Achieving a high thermally conductive value while maintaining, both durable adhesion and a stable elastomeric modulus, is a material technology challenge. An efficient combination of fillers combined with the proper chemistry can provide the expected performance. After an introduction on the role of silicone materials in thermal management and the formulation options, this Webinar describes and compares several thermal material solutions for electric vehicles Battery pack.


  1. Learn how a passive thermal management system enhances performance and safety of battery packs.
  2. Understand the role and benefits of silicone materials in thermal management
  3. Learn to identify a suitable thermal material in respect of form, physicals properties and processability tailored to the application design (battery pack) and prevent the usual focus on the thermal conductivity as the sole selection criteria.
  4. Develop a good understanding of the TIM (thermal interface material) performance optimisation possibilities.
  5. Learn on the impact of fillers on TIM performance


  1. Introduction on the role of silicone materials in thermal management
  2. The formulation options: comparison of different filler types and combination performances
  3. Maintaining an interfacial surface contact to assure heat flow stability during assembly lifetime
  4. The design impact on the TIM selection – Illustration: from the modular design (cell to pack) to structural pack design (cell to chassis) 

Who Should Attend:
