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.
The thermal spreading interval between the thermal runaway battery and the neighboring batteries in the module is increased to an infinite length, and only the thermal runaway battery shows the phenomenon of spraying valve such as fire and smoke. It is expected to have a guidance for the design of thermal insulation in lithium-ion battery modules.
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.
The battery pack consists of pouch cells connected in series with necessary internal components such as wiring, battery management system, cooling plates, and metallic housings. The customized pack is similar to the battery pack used in our electric mobility applications.
In view of the limited literature on the usage of commercially available thermal barrier materials in the battery pack to prevent cell-to-cell thermal runaway propagation, we characterize the thermal performance of different materials and the usage of selected materials in a battery pack-level overheating test.
Li-ion battery packs comprise many individual battery cells grouped together in modules. The modules are enclosed in a structure to provide support, stiffness, electrical insulation, and chemical resistance to the entire module structure. These can be comprised of metallic or polymeric materials.
