From a thermal management standpoint, a minimum of two discrete thermal interface materials (TIMs) or “ gap fillers ” (GF) are typically employed in the current, modular-based, battery pack configuration, as illustrated in Figure 2.
A comparative study on four types of thermal insulating materials for battery packs has been carried out in . Among the studied materials: thermal insulating cotton, ceramic cotton fibre, ceramic carbon fibre and aerogel, the flame test results of aerogel material show promising results for its use as insulation material in battery packs.
Thermally conductive adhesives play a crucial role in electric vehicle (EV) battery packs by addressing the critical need for efficient heat management. EV battery packs generate significant heat during operation, which can negatively impact their performance, lifespan, and safety.
These materials inherently provide breathability inside the battery pack, specifically suitable for pouch cells with noticeable volume expansion. Even though the materials are classified to withstand a temperature of 1200 °C, the withstand time depends on the thickness and fire properties.
The graphite sheets are flexible and can go as thin as 0.85 mm, which is the lowest in the considered materials with acceptable thermal performance. Comparatively, graphite sheets are cheaper than most of the discussed thermal insulation materials. These properties make graphite sheets suitable as interstitial material of battery pack insulation.
Thermally Conductive Adhesives (TCAs) are key Thermal Interface Material (TIMs) used in Cell-to-Pack configurations, providing structural bonding and thermal conductivity. In this configuration TCAs are dispensed on the inside of the battery case and cells are then stacked in the case to create the battery pack structure.
