Why Do EV Battery Modules Need Aerogel Insulation Pads?
When one EV battery cell enters thermal runaway, heat can spread to neighboring cells and turn a localized failure into a module-level fire. The most effective passive solution is to place a validated aerogel insulation pad between adjacent cells or other critical heat-transfer paths. Aerogel provides high thermal resistance with relatively little thickness, making it attractive for compact, energy-dense EV battery modules.

READ MOREHow to Prevent Thermal Runaway Propagation in EV Battery Packs？
This technical report addresses a critical safety challenge in electric vehicles: mitigating catastrophic battery thermal runaway. It analyzes why conventional polyurethane or plastic cell spacers fail under extreme heat, leading to structural collapse and fire propagation. The report presents high-performance ceramic silicone foam sheets as the definitive engineering solution. When temperatures exceed 1000°C, this advanced elastomer undergoes an endothermic, ceramifiable chemistry transformation, turning into a rigid, non-conductive ceramic shield. Supported by a comparative data matrix against standard PU foams and traditional aerogels, the document demonstrates how ceramic silicone maintains physical integrity, handles cell swelling via compression elasticity, and blocks high-pressure toxic gases. Validated by UL 94 V-0 flammability metrics and SAE international automotive safety guidelines, this material ensures strict compliance and passenger safety in next-generation EV battery p
