Lithium Battery Coating Process Optimization: Propelling the Lithium Battery Industry Forward

In the fast - evolving lithium battery industry, the pursuit of higher - performance, more cost - effective batteries is relentless. Lithium battery coating process optimization has emerged as a crucial factor in meeting these demands, significantly influencing battery performance, safety, and production efficiency.

Lankwitzer, a leading player in the battery coating sector, has been actively engaged in optimizing lithium battery coating processes. At the 3rd eic Three - Electric and Energy Storage “Insulation, Flame Retardancy, Heat Insulation, and Sealing” Technology Conference in 2024, Lankwitzer shared its latest breakthroughs in lithium battery coating process optimization. The company’s experts emphasized their commitment to improving the quality and efficiency of coating processes.

Lankwitzer’s Evoprotect455UV series represents a remarkable achievement in lithium battery coating process optimization. The development of Evoprotect455UV (UE55 - 0500/0) took three years, and it entered production in 2018. With a production volume exceeding 4,000 tons and an initial operation pass rate of over 98%, this product has been widely adopted on 24 cell - coating production lines in Germany and China, coating more than 500 million battery cells. The large - scale application is a testament to the optimized coating process, which ensures stable product quality.

The optimized lithium battery coating process of Lankwitzer brings multiple benefits. In terms of performance, the company’s coatings enhance battery safety. The excellent insulation properties of Evoprotect455UV series prevent short - circuits, a major safety concern in lithium - ion batteries. In the electric vehicle (EV) industry, this is of utmost importance as short - circuits can lead to catastrophic failures. Also, the coatings improve the adhesion between electrodes and electrolytes, optimizing ion transfer during charging and discharging. As a result, the battery’s charging speed and overall energy efficiency are enhanced.

Cost - effectiveness is another advantage of Lankwitzer’s optimized lithium battery coating process. The coatings have an excellent recycling performance, with a comprehensive utilization rate of up to 95%, which significantly cuts down costs. The production cycle of Lankwitzer’s coating process can meet 50 - 60 ppm, ensuring high production efficiency. Additionally, Lankwitzer’s Shanghai Testing Center has established a full - process spraying line. This not only helps customers save the investment in building a UV spraying trial - production line but also provides customized spraying services, further reducing costs for customers.

In the energy storage power station scenario, Lankwitzer’s optimized lithium battery coating process has enabled energy storage batteries to endure 1,000 hours of high - temperature and high - humidity aging tests. This ensures the stable operation of energy storage systems over an extended period.

Thanks to its optimized lithium battery coating processes, Lankwitzer has provided coatings for over 450 million commercial battery cells. These cells are installed in more than 2 million electric vehicles and plug - in hybrid vehicles, covering global markets. As the demand for lithium batteries continues to grow, Lankwitzer’s continuous innovation in lithium battery coating process optimization will further drive the development of the lithium battery industry.
