New energy battery insulation coating: the key shield of new energy development
In the wave of vigorous development of the new energy industry, the importance of new energy battery insulation coatings as a key material to ensure the safe and stable operation of batteries has become increasingly prominent. It is not only the "safety guard" of new energy batteries, but also an important force to promote the new energy industry to a higher level.
With the widespread popularity of new energy vehicles and energy storage equipment, higher requirements have been put forward for the performance and safety of new energy batteries. New energy batteries in the charge and discharge process, will produce a lot of heat and current, if there is no effective insulation protection, easy to cause short circuit, leakage and even fire explosion and other serious accidents. The new energy battery insulation coating can form a dense protective film on the surface of the battery, effectively isolate the current and heat, prevent mutual interference between the internal components of the battery, and greatly improve the safety and stability of the battery.
From the market data point of view, the new energy battery insulation coating market has shown a rapid development trend. In 2024, China's power battery "insulation and voltage resistance, flame retardant and fire protection" coating market can reach 13.9 billion yuan, an increase of 19.80% from 2023. This significant growth trend reflects the huge demand for new energy battery insulation coatings in the field of new energy. Major coating companies have increased investment in research and development, and actively layout this market. For example, an invention patent disclosed by Libang "an insulating and flame retardant coating with fire resistance and its preparation method and application", the coating can effectively protect the entire power battery system when the power battery single cell or multiple cells occur thermal runaway, ensuring that there is no fire or explosion within 5 minutes, and fighting for precious time for personnel escape.
In terms of technological innovation, the evoprotect455uv series of cell UV insulation coatings developed by Lanwei Coatings perform well. The coating curing time is extremely short, only a few seconds to complete spraying and curing, supporting automated production, greatly improving production efficiency and reducing labor costs. And the paint recovery rate is close to 100%, which is both environmentally friendly and economic. Currently, the coatings are used on 26 cell coating lines in Germany and China, providing reliable protection for more than 450 million commercial battery cells.
In addition, some new types of new energy battery insulation coatings also have good adhesion, water resistance, wear resistance and impact resistance, and can maintain a stable protective effect in complex and harsh environments. In the future, with the continuous breakthrough of new energy technology, new energy battery insulation coatings will develop in the direction of higher performance, more environmentally friendly and more intelligent. It will continue to meet the growing safety and performance needs of new energy batteries, provide a solid guarantee for the sustainable development of the new energy industry, continue to shine in the new energy era, and help new energy vehicles and energy storage equipment and other industries to a new height.
