With the rapid development of the new energy vehicle industry, the performance and safety of power batteries have attracted much attention, and the technical requirements for the latest power battery coatings have also been continuously improved. Among them, high-performance insulation has become a key point.
With the development of new energy vehicles towards high energy density and high voltage platforms, the current intensity and voltage inside the power battery have increased significantly. This makes the insulation performance requirements for battery coatings reach a new height. Taking the 800V voltage platform as an example, traditional battery insulation protection has been difficult to meet the demand, and new power battery coatings need to have higher breakdown resistance voltage, from the traditional 2500V to 3000-4000V. The UV insulating battery coating (EvoProtect 455 UV) developed by Lankwitzer's Lanwei Coatings (Shanghai) Co., Ltd. is excellent in this regard. The coating can effectively isolate the internal current of the battery, prevent short circuits and other safety accidents, and its insulation performance indicators such as breakdown voltage far exceed the industry average, meeting the technical requirements of the new generation of power batteries with high voltage.
The stability of the insulating coating is also an important consideration. During the charging and discharging process of the battery, heat and vibration are generated, and the working environment of the battery is complex and changeable. This requires the coating to maintain stable insulating properties under different temperature, humidity and mechanical stress conditions. Lankwitzer's EvoProtect 455 UV coating is specially formulated to ensure reliable insulation performance after high and low temperature cycles, high humidity environments and mechanical vibration tests, ensuring the safe operation of the battery under various operating conditions.
In addition, accurate insulation protection is also part of the latest technical requirements. The internal structure of power batteries is complex, and there are differences in insulation requirements in different parts. The latest power battery coatings need to be able to accurately apply on key parts to achieve accurate insulation protection. The EvoProtect 455 UV coating adapts to high-precision inkjet processes and can accurately apply paint on key parts of the battery cell, meeting this technical requirement, avoiding unnecessary paint waste, while improving the overall performance of the battery.
From the perspective of industry development trends, with the continuous expansion of the new energy vehicle market and the continuous innovation of battery technology, the technical requirements for high-performance insulation of power battery coatings will become more and more stringent. Only by continuously investing in research and development to improve the insulation performance of products can companies occupy a place in the fierce market competition. Like Lankwitzer, through continuous technological innovation, its products have been widely used in a number of battery coating production lines in Germany and China. The battery coating volume exceeds hundreds of millions, which has been fully recognized by the market and set a model for meeting the latest power battery coating technical requirements.
