New Energy Vehicles: Silicone Builds a Solid Safety Barrier for the “Electric Heart”

In today’s rapidly evolving new energy vehicle (NEV) industry, silicone has long evolved from an “auxiliary material” to a “core safeguard.” Compared with traditional fuel vehicles that use only 2.5 kg per car, NEVs consume up to 20 kg of silicone—nearly a tenfold increase—reflecting its irreplaceable performance advantages.
As the “heart” of an electric vehicle, the battery pack’s safety directly determines the vehicle’s value. Silicone sealants, with their superior sealing properties, completely isolate battery modules from the external environment. Even when the vehicle wades through water or operates in humid conditions, they effectively block moisture and dust, preventing short-circuit risks at the source. Meanwhile, the large amount of heat generated during battery operation—often the “culprit” behind performance degradation—can be efficiently managed with silicone thermal gels and greases, which form a high-efficiency heat dissipation network that quickly transfers localized heat to cooling components, keeping the battery temperature within the optimal range and extending service life by more than 30%.
In electric drive systems, silicone’s resistance to extreme temperatures excels—it withstands the heat of motor operation and the cold of northern winters while maintaining insulation stability. During vehicle lightweighting, silicone adhesives serve as the “perfect partner” for new materials like aluminum alloys and carbon fiber, providing strong bonding while reducing weight and improving range. From battery to body, silicone’s comprehensive protection network has become key to NEV safety upgrades.
