With the booming development of the new energy vehicle industry, the performance and safety of power batteries have become the focus of the industry. UV battery coatings are playing an increasingly critical role as an important material to ensure the stable operation of power batteries. With the continuous expansion of the new energy vehicle market, consumers' requirements for vehicle range, charging speed and safety performance continue to increase, which makes the technological innovation of power batteries imminent, and UV battery coatings play an indispensable role in it.
In terms of performance improvement, the UV insulating battery coating (EvoProtect 455 UV) developed by Lankwitzer's Lanwei Paint (Shanghai) Co., Ltd. performs exceptionally well. The coating is irradiated with ultraviolet rays to achieve ultra-fast curing, and the whole process takes less than 5 seconds, greatly improving production efficiency. In the production of power batteries, fast curing means that a large number of cells can be coated in a short time to meet the market demand for battery capacity. Moreover, it supports automated production, enabling continuous production lines without human intervention, reducing the impact of human factors on product quality, ensuring the consistency and stability of each cell coating.
In terms of safety protection, the insulation performance of UV battery coatings is crucial. The EvoProtect 455 UV coating can effectively isolate the current inside the battery and prevent the occurrence of safety accidents such as short circuits. It adapts to high-precision inkjet processes and can accurately apply the paint to the key parts of the battery cells to achieve accurate insulation protection. At the same time, the coating is also an environmentally friendly product, in line with the current trend of green development in the automotive industry. At present, the product has been widely used in several battery coating production lines in Germany and China, with more than hundreds of millions of batteries coated, and the market feedback is good.
Compared with traditional battery insulation protection methods, such as PET \"blue film\" coating, UV battery coatings have obvious advantages. Take the all (high) solid UV insulating coating developed by Hunan Dijing New Materials Co., Ltd. as an example. As a substitute for \"blue film\", it has better performance in insulation, voltage resistance, wear resistance, weather resistance, and anti-aging. \"Blue film\" may have problems such as aging and falling off during long-term use, which affects the insulation effect of the battery. With its good adhesion and stability, UV battery coatings can provide more durable and reliable protection for power batteries.
At the market application level, many battery manufacturers and automakers have adopted UV battery coating technology. On January 14, 2025, SAIC Passenger Vehicle Central Laboratory and MF Material Coating jointly organized an exchange and discussion. Lanwei Coatings introduced its UV insulating coating development results, which can achieve room temperature curing, and the qualified rate of finished materials can reach 90%, attracting the attention of many enterprises. Jinlitai also received an order from a leading new energy battery company to provide insulating coating materials and coating process verification for its battery products, which shows the broad application prospects of UV battery coatings in the field of new energy vehicle power batteries.
