Battery Cell Coating: Lankwitzer’s Innovative Solutions Powering the Battery Industry

In the dynamic battery industry, battery cell coating is of great significance. As the demand for high - performance, reliable batteries continues to soar across various sectors such as electric vehicles (EVs), energy storage systems, and portable electronics, the quality of battery cell coatings becomes a key determinant of battery performance, safety, and lifespan.

Lankwitzer, a leading company in the battery coating domain, has been actively driving innovation in battery cell coating. At the 3rd eic Three - Electric and Energy Storage “Insulation, Flame Retardancy, Heat Insulation, and Sealing” Technology Conference in 2024, Lankwitzer made a splash with its latest battery cell coating solutions. The company’s representatives emphasized their unwavering commitment to developing advanced products to meet the diverse and demanding requirements of the battery market.

Lankwitzer’s Evoprotect455UV series serves as a prime example of its prowess in battery cell coating. Evoprotect455UV (UE55 - 0500/0), developed over three years, entered production in 2018. With an impressive production volume exceeding 4,000 tons and an initial operation pass rate of over 98%, it has been extensively applied on 24 cell - coating production lines in Germany and China, coating more than 500 million battery cells. This wide - scale adoption speaks volumes about its reliability and effectiveness.

Evoprotect455UV (UE55 - 0500/7), launched in 2023, further showcases Lankwitzer’s technological capabilities. Even after enduring 1,000 hours of 85/85 aging tests, it still meets customized customer requirements. Boasting a shear strength of over 12mpa, low curing energy, an insulation withstand voltage of more than 6kvdc, and a dielectric strength of over 150kv/mm, this product effectively safeguards the long - term stability and performance of battery cells.

Lankwitzer’s battery cell coatings offer multiple advantages. The UV - curing technology allows the coating to solidify in less than 5 seconds, with a production cycle that can reach 50 - 60 ppm. This significantly boosts production efficiency and cuts down time - related costs. In terms of environmental protection and cost - control, the coatings exhibit excellent recycling performance, with a comprehensive utilization rate of up to 95%. They also generate almost no volatile organic compounds (VOCs) during the curing process, aligning with strict environmental standards.

In the EV industry, Lankwitzer’s battery cell coatings have delivered remarkable results. A well - known EV manufacturer adopted Lankwitzer’s coatings, and the battery modules in their vehicles demonstrated enhanced performance. After 5,000 charge - discharge cycles, the capacity retention rate was over 85%, far surpassing the industry average.

Lankwitzer’s Shanghai Testing Center, equipped with a full - process spraying line, offers customized spraying services for battery cells. This enables customers to save the investment in building a trial - production line and accelerates the implementation of new technologies.

Thanks to its consistent innovation, Lankwitzer has provided battery cell coatings for over 450 million commercial battery cells. As the battery industry continues to evolve, Lankwitzer’s advanced battery cell coatings will play an even more significant role in propelling the industry forward.
