Fluorosilicone oil has shown important application value in the field of new energy due to its unique properties such as high and low temperature resistance, chemical corrosion resistance, and low surface tension, which is specifically reflected in the following aspects:

1. Lithium battery safety protection
‌Thermal runaway protection‌: The modified silicone oil insulation system is applied to lithium battery modules, which can significantly delay the propagation of thermal runaway for more than 30 minutes, while maintaining an insulation resistance of up to 100MΩ in high temperature and high humidity environments, greatly improving battery safety.
‌Puncture short circuit protection‌: This system can reduce 98% of the puncture short circuit current and enhance the stability of the battery pack

2. Insulation materials for power equipment
‌Transformer innovation‌: In 500kV substations, the use of dimethyl silicone oil instead of mineral oil can increase the transformer ignition point from 160℃ to 316℃, extend the maintenance cycle to 8 years, and significantly improve the overload capacity
‌Supercapacitor optimization‌: The power capacitor impregnated with methylphenyl silicone oil has a capacitance increased to 4.7 times that of traditional products, an operating temperature range extended to -40℃~150℃, and a cycle life of more than 100,000 times.
‌Superhydrophobic insulation coating‌: Silicon carbide/fluorocarbon resin superhydrophobic coating (fluorine-containing silicon material) has excellent hydrophobicity and charge dissipation characteristics, and the wet flash voltage is increased by 90.6% compared with traditional coatings, which is suitable for power equipment in high humidity environments.

3. Key materials for fuel cells and hydrogen energy systems
Corrosion-resistant seals: Fluorosilicone (fluorinated silicone oil derivatives) are used for turbocharger pipes, crankshaft oil seals and other components of fuel cells. They can withstand strong corrosive media (such as hydrogen and acidic environments) to ensure long-term stable operation of the system.
High temperature adaptability: Oil-resistant seals and fuel hoses made from vinyl fluorosilicone oil can maintain performance under -60℃~200℃ working conditions, meeting the stringent temperature requirements of hydrogen fuel cells.

4. Material preparation and recycling technology
Precision polymerization process: Hydroxyl fluorosilicone oil is synthesized by ring-opening polymerization, and the degree of polymerization can be controlled in the range of 5~50, meeting the molecular weight requirements of different application scenarios.
Treatment of fluorine-containing wastewater: The ion exchange resin method (such as defluorination resin) efficiently removes fluoride ions from monocrystalline silicon production wastewater, reduces treatment costs, and helps the green production of new energy materials.
Industry Trends and Market Prospects
The global fluorosilicone oil market continues to grow, with a scale of US$226 million in 2023 and is expected to reach US$455.6 million in 2031 (CAGR of 8.1%), mainly driven by the demand for high-performance materials in the new energy field.

In summary, fluorosilicone oil has become an indispensable functional material in the new energy industry by improving battery safety, optimizing the insulation performance of power equipment, and ensuring the sealing reliability of fuel cells. Its technological innovation and standardization process will further support the high-quality development of the industry.
