Electric vehicle insulation and battery safety are facing new challenges
With the rapid popularization of electric vehicles, battery insulation and fire prevention are becoming major issues that automakers must confront. Especially the safety hazards caused by battery thermal runaway have become a highly concerned issue in the industry and among users.
In recent years, reports about self-ignition and collision fires of electric vehicle batteries have been frequent, and a considerable proportion of them are closely related to battery thermal runaway. Once heat spreads rapidly among battery cells, it may lead to a chain reaction of thermal diffusion, thereby endangering the safety of the entire vehicle. Therefore, the development of new and highly efficient heat insulation and fireproof materials can not only prevent the spread of high temperatures but also effectively delay the risks caused by thermal runaway, thus buying more escape time for passengers.
Insufficient low-temperature performance: In winter environments, battery packs are prone to malfunction due to excessively low temperatures and require advanced insulation materials to maintain stable performance.
Risks of traditional materials: Common organic foam insulation materials are flammable and release a large amount of toxic smoke when burning, seriously threatening the respiratory and nervous systems of passengers.
Space constraints: The internal space of electric vehicles, especially battery packs, is limited. Traditional complex insulation materials are difficult to apply, and there is an urgent need for new insulation solutions that are ultra-thin, convenient and efficient.
Against this backdrop, new types of inorganic, non-toxic, fire-resistant and ultra-thin thermal insulation materials are becoming a key research and development direction in the industry. Among them, aerogel, with its excellent thermal insulation performance, fire resistance and lightweight characteristics, is regarded as an ideal choice for thermal management and fire safety of electric vehicle batteries.
Aerogel for New Energy
Aerogel as new energy by providing superior thermal insulation for efficiency in buildings, industrial processes, and EVs, and by enabling advanced energy storage (batteries, supercapacitors) and conversion (solar thermal, catalysts) due to its low density, high surface area, and conductivity. Key applications include ultra-efficient insulation blankets, smart windows, components for faster-charging batteries, and materials for hydrogen storage and solar energy capture, promising significant carbon reduction and sustainable energy solutions.
Extreme Insulation: Unmatched thermal resistance ("frozen smoke").
Lightweight: Extremely low density, ideal for subsea and aerospace.
High Surface Area: Crucial for catalysis and storage.
Conductivity (Carbon Aerogels): Excellent electrical conductivity for battery and supercapacitor electrodes.
Energy Efficiency & Insulation:
Buildings: Aerogel insulation dramatically boosts R-values, reducing heating/cooling energy, with innovations in transparent aerogels for smart windows.
Industrial/Oil & Gas: Used in LNG facilities, distillation towers, and subsea pipelines for significant energy savings and lower emissions.
Electric Vehicles (EVs): Provides thermal management for batteries, improving safety and performance.
Energy Storage:
Batteries & Supercapacitors: Carbon aerogels enhance electrode performance, allowing for faster charging and longer life in batteries and supercapacitors.
Hydrogen Storage: Their high surface area makes them ideal for storing hydrogen, a key clean fuel.
Energy Conversion & Capture:
Solar Thermal: Used in solar collectors for efficient water and space heating.
Catalysis: Carbon aerogels act as efficient catalysts in various energy processes.
Advanced Materials:
Cellulose Aerogels: Biodegradable, renewable options with excellent properties for sustainable applications.
Smart Windows: Thermochromic aerogel films adjust solar transmittance for better building efficiency.
