In today's rapidly evolving new energy vehicle industry, battery safety has become one of the most critical concerns for consumers. Liquid silicone rubber (LSR), a seemingly ordinary material, is quietly emerging as the "safety guardian" of new energy vehicle batteries, providing comprehensive protection.

LSR offers outstanding sealing performance and chemical corrosion resistance. In the battery packs of new energy vehicles, LSR is used for sealing rings, fitting tightly at the juncture between the battery pack housing and cover, effectively blocking the ingress of rainwater and dust. At the same time, it resists potential corrosion from the electrolyte during battery operation, preventing short circuits or fire risks caused by sealing failure. Even under extreme temperature conditions – from -60°C cold to 200°C heat – LSR maintains excellent elasticity, ensuring stable sealing performance.

Beyond sealing, LSR also plays an important role in battery heat dissipation. Batteries generate significant heat during charging and discharging. If this heat is not dissipated in a timely manner, it can lead to battery capacity degradation or even thermal runaway. Thermally conductive pads made from LSR, filled between individual battery cells, efficiently transfer heat to the cooling plate, maintaining uniform temperature distribution across the battery and extending its service life.

Furthermore, LSR offers good insulation properties. At the interfaces between battery terminals and wiring harnesses, LSR insulating sleeves withstand voltages above 300V, blocking current leakage and providing reliable insulation protection for the battery's high-voltage operating environment. This comprehensive protection makes new energy vehicle batteries safer and more reliable.
