Fluorosilicone oil drives innovation in new energy equipment: Technological breakthroughs in wind power and energy storage systems

1.The demand for wind power equipment maintenance has exploded, and fluorosilicone oil has become the core solution
With the rapid growth of global wind power installed capacity, the demand for high-performance lubricating materials in the equipment maintenance field has soared. The new type of fluorosilicone oil maintains stable lubrication performance within a wide temperature range of -70 ℃ to 280℃ by optimizing its molecular structure, which can significantly extend the service life of key components such as gearboxes and bearings. Experimental data shows that the major overhaul cycle of wind power gearboxes using fluorosilicone oil has been extended from 500,000 kilometers to 800,000 kilometers, with maintenance costs reduced by 35%.
In terms of adaptability to extreme environments, fluorosilicone oil has a salt spray resistance of over 5,000 hours, effectively resisting the erosion of high humidity and high salt content in coastal areas. The measured data of a certain offshore wind farm shows that the equipment failure rate using fluorosilicone oil is 60% lower than that of traditional grease, and the annual power generation increases by 12%.

2. The thermal management technology of energy storage systems has been upgraded, opening up new scenarios for fluorosilicone oil
The requirements for thermal conductivity and fire resistance in the energy storage field have driven the technological iteration of fluorosilicone oil. The thermal conductivity of the new type of thermal conductive fluorosilicone oil reaches 0.25W/(m · K), which can meet the heat dissipation requirements of lithium battery modules. Meanwhile, its flame-retardant property enables the energy storage system to remain stable even when the battery cells are thermically out of control, meeting the UL94 V-0 fire protection standard. The latest technology roadmap of CATL shows that the purchase volume of fluorosilicone oil for energy storage will increase by 75% year-on-year in 2025.
In the field of hydrogen fuel cells, the hydrogen brittleness resistance of fluorosilicone oil has become a key technological breakthrough. The hydrogen embrittlement resistant fluorosilicone oil developed by Shanghai Jiao Tong University has passed the 1,000-hour durability test, successfully solving the corrosion problem of metal parts and extending the lifespan of the stack to over 8,000 hours. The related products have entered the supply chain systems of leading domestic enterprises.

3. Catalytic technology innovation promotes the large-scale application of fluorosilicone oil
The application of the two-component catalytic system has significantly improved the production efficiency and product performance of fluorosilicone oil. By combining the temporary catalyst with the permanent catalyst, the reaction temperature was reduced from 130℃ to below 100℃, and at the same time, the volatile problem of traditional lithium-based catalysts was avoided, increasing the preparation efficiency of high-molecular-weight fluorosilicone oil by 40%. This new type of technology has built a pilot production line with an annual output of 5,000 tons in Shandong, and the product performance has reached the international leading level.
On the raw material side, the domestic production capacity of silicone monomers is expected to exceed 6 million tons by 2028, and the prices of key raw materials will drop by 15% to 20%, providing a cost advantage for the large-scale production of fluorosilicone oil. The research and development of bio-based fluorosilicone oil is advancing simultaneously. The proportion of renewable raw materials has reached 60%, and the energy consumption in the production process has been reduced by 45%. It has passed the EU REACH certification.

4. The dual drivers of policy dividends and green transformation drive the development of the industry
The "14th Five-Year Plan" of the country has listed special lubricating materials as a key development area. The fiscal subsidies and tax preferential policies will last until 2027, directly promoting the technological upgrading of fluorosilicone oil enterprises. A leading enterprise has reduced the carbon emissions of fluorosilicone oil production to 3.2 tons of CO₂ per ton through photovoltaic power generation and waste heat recovery systems, a 58% decrease compared to the industry average, and has been recognized as a green manufacturing demonstration project by the Ministry of Industry and Information Technology.
In international competition, domestic fluorosilicone oil has rapidly replaced imported products by virtue of its cost-performance advantage. The fluorosilicone oil for wind power of a certain enterprise has passed the DNV GL certification. Its price is only 70% of that of similar products in Germany. The market share in Europe is expected to exceed 15% in 2025. The international standard "Test Method for Fuel Resistance of Fluorosilicone Oil" (ISO 23045), led and formulated by China, has been officially implemented, filling the international gap in this field.
In the next five years, with the in-depth advancement of the "dual carbon" goals, the application of fluorosilicone oil in the new energy sector will continue to deepen. It is estimated that by 2030, the market size of fluorosilicone oil in the wind power and energy storage sectors will exceed 800 million yuan and 1.5 billion yuan respectively, becoming the core engine driving the growth of the industry.
