Battery insulation coating: the key guarantee for the development of new energy
With the rapid expansion of the new energy vehicle market, the requirements for battery performance and safety are becoming more stringent. As the "protective coat" of the battery, the battery insulation coating can effectively isolate the current and prevent safety hazards such as short circuit and leakage. For example, when the electronic components inside the battery fail, the insulating coating can prevent the abnormal conduction of current and avoid causing serious accidents such as fire or explosion.
Market data show that 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 growth trend reflects the huge demand for battery insulation coatings in the field of new energy. The major coating companies have layout, such as Libang has disclosed an invention patent "a kind of fire resistant flame retardant insulation coating and its preparation method and application", the coating can protect the entire power battery system when the power battery single cell or multiple cells occur thermal runaway, to ensure that no fire does not explode within 5 minutes, and reserve time for personnel escape.
In terms of technological innovation, the evoprotect455uv series of cell UV insulation coatings developed by Lanwei Coatings perform well. Its short curing time can support automated production and greatly improve production efficiency. And the paint recovery rate is close to 100%, which effectively reduces the production cost and environmental pollution. The coatings are used on 26 cell coating lines in Germany and China, protecting more than 450 million commercial battery cells.
In addition, some new battery insulation coatings also have good adhesion, water resistance, wear resistance and impact resistance, which can maintain a stable protection effect in complex environments. In the future, with the continuous breakthrough of new energy technology, battery insulation coatings will develop in the direction of higher performance, more environmentally friendly and more intelligent, providing a solid guarantee for the sustainable development of the new energy industry. Whether it is a new energy vehicle, or energy storage equipment, can not be separated from the escort of battery insulation coating, it will continue to shine in the new energy era.
