Lankwitzer's Breakthroughs in Lithium Battery Coating Process Optimization
In the dynamic landscape of the lithium - battery - driven energy storage and electric vehicle industries, the optimization of the lithium battery coating process has become a focal point for enhancing battery performance, durability, and safety. As the global demand for high - quality lithium batteries continues its upward trajectory, companies are scouring the market for innovative solutions. Lankwitzer, a renowned name in the coating manufacturing sphere, has been at the forefront of revolutionizing the lithium battery coating process.
Lankwitzer, established in 1952 as Lankwitzer Germany Premium Coating, has a rich legacy of delivering top - notch industrial coating solutions. Their "Made in Germany" products are a testament to their commitment to quality, flexibility, and continuous innovation. This expertise has been particularly evident in their foray into lithium battery coating process optimization.
One of the key aspects of Lankwitzer's lithium battery coating process optimization lies in their UV - curing technology, as exemplified by their Evoprotect455UV coating. When applied to lithium - ion batteries, this coating offers a multitude of benefits. The curing process is incredibly rapid. With ultraviolet irradiation, the coating can be fully cured in under five seconds. This short curing time is a boon for lithium battery manufacturers as it significantly reduces the overall production cycle. In high - volume production scenarios, this time - saving aspect can translate into substantial cost savings.
Moreover, the Evoprotect455UV coating is engineered to support automated production lines. Lithium battery manufacturing often requires high - precision and high - volume output. By integrating this coating into unmanned continuous production lines, Lankwitzer ensures stability and reliability in the coating application. This not only cuts down on labor costs but also minimizes the risk of human - error - induced defects. The coating's compatibility with high - precision inkjet processes further refines the coating application. Each lithium - battery cell can be coated with utmost precision, ensuring a uniform and high - quality finish. This uniform coating is crucial for maintaining consistent battery performance across an entire batch.
In terms of performance, Lankwitzer's lithium battery coatings, such as Evoprotect455UV, offer excellent protection against environmental factors. Lithium batteries are often exposed to harsh conditions, including humidity, temperature fluctuations, and chemical contaminants. The coating acts as a robust shield, preventing long - term atmospheric and chemical degradation of the battery cells. This protection mechanism significantly extends the lifespan of lithium batteries, which is a critical factor for both electric vehicle manufacturers and energy storage system providers.
When compared to traditional coating methods used in lithium battery production, Lankwitzer's approach stands out. Traditional PET blue films, for instance, have adhesion issues that can compromise the safety and reliability of lithium - ion batteries. Lankwitzer's UV - cured coatings, on the other hand, exhibit superior adhesion properties, ensuring a more secure and long - lasting bond with the battery surface. In comparison with epoxy and powder coatings, Lankwitzer's solutions also show an edge in production efficiency, insulation performance, and edge coverage, all of which are vital for high - performance lithium batteries.
Lankwitzer's energy storage & power cell UV insulating coating Evoprotect455UV (UE55 - 0500/0) has been a resounding success in the market. After three years of intensive R & D, it was launched into production in 2018. With a production volume surpassing 4000 tons and a first - run qualification rate of over 98%, it has been widely adopted across 24 cell - coating production lines in Germany and China, having coated over 500 million batteries. It has a shear strength greater than 12mpa, low curing energy, an insulation withstand voltage greater than 6kvdc, a dielectric strength greater than 150kv/mm, and an insulation resistance > 10gω. Even after 1000 hours of 85/85 aging tests, it still meets customized customer requirements. This product's high recycling performance, with a comprehensive utilization rate of up to 95% and a finished - product yield of over 99% when using recycled products, also aligns with the growing trend towards sustainable manufacturing in the lithium - battery industry.
