Lithium Battery Coating Process Optimization: Lankwitzer’s Pioneering Approach
In the fast - paced lithium battery industry, lithium battery coating process optimization is of utmost importance. As the demand for high - performance, long - lasting lithium batteries continues to rise, the coating process significantly impacts battery safety, performance, and production efficiency. Many companies are vying to optimize this process, and Lankwitzer has emerged as a pioneer.
At the 3rd eic Three - Electric and Energy Storage “Insulation, Flame Retardancy, Heat Insulation, and Sealing” Technology Conference in 2024, Lankwitzer, a leading player in the field, shared its profound insights on lithium battery coating process optimization. The company introduced its Evoprotect455UV series, which represents a significant leap forward in lithium battery coating.
Lankwitzer’s Evoprotect455UV series incorporates a revolutionary UV - curing technology, which is a key aspect of its lithium battery coating process optimization. This technology allows the coating to solidify in less than 5 seconds, with a production cycle reaching 50 - 60 ppm. As a result, production efficiency has been significantly enhanced. A large - scale lithium battery manufacturer reported a nearly 30% increase in production efficiency after adopting Lankwitzer’s coating process. This not only shortens the production cycle but also reduces time - related costs.
Another remarkable aspect of Lankwitzer’s lithium battery coating process optimization lies in coating recycling. The company has achieved a recovery rate of nearly 100% and a comprehensive utilization rate of 95% for its coatings. The high - quality recycled coatings contribute to a finished - product yield rate of over 99%, further cutting down production costs.
In terms of product performance, the Evoprotect455UV (UE55 - 0500/7) offers outstanding features. It has an insulation withstand voltage of more than 6 kVdc and a dielectric strength of over 150 kV/mm. Even after 1000 hours of 85/85 aging tests, it can still meet customized requirements. Lankwitzer customized its UV Insulation Battery Coating (Evoprotect455UV) for BMW. This optimized coating effectively protects battery units from long - term atmospheric and chemical influences. Compared to traditional PET blue films, it has superior adhesion, meeting BMW’s strict requirements for lithium battery safety and performance.
Lankwitzer’s Shanghai Testing Center, equipped with a full - process automated spraying line, plays a crucial role in lithium battery coating process optimization. It provides customized spraying services, helping clients save the investment in building UV spraying trial - production lines. The center can also optimize lithium battery coating processes promptly based on client feedback.
To date, Lankwitzer has provided coatings for over 450 million commercial lithium battery units. These units are widely used in more than 2 million electric vehicles and plug - in hybrid vehicles, as well as numerous energy storage projects, covering global markets.
