Thermo-responsive materials have been extensively used for lithium batteries with high performance and high safety. Types of reversibly thermo-responsive materials and their response mechanism to temperature were classified.
However, using these heat-resistant or flame-retardant materials can only delay but not weaken or even eliminate the attack of thermal runaway, and also cannot endow the battery with shutdown or reusability especially as the temperature that batteries are subjected to is not going to keep rising.
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.
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.
