Under the high temperatures of End of Heat, thermal management in new energy vehicle (NEV) battery packs faces challenges. Silicone rubber seals are extensively used within battery modules, enduring extreme temperatures from -50°C to 250°C to ensure sealing and prevent short circuits. Silicone gel potting materials provide cushioning and protection for battery cells, effectively absorbing shocks from rough roads. Industry data shows penetration rates for organic silicone materials in domestic electric vehicles exceeded 80% in 2023. Some companies are developing polysilazane coatings for battery packs to further enhance fire resistance, making material innovation a new frontier in EV safety.
