Insulation Material for Battery Cells: Lankwitzer’s Innovation Driving Industry Advancement

In the fast - evolving battery industry, insulation material for battery cells has emerged as a crucial element. As the demand for high - performance and safe batteries surges across various sectors, especially in electric vehicles (EVs) and energy storage systems, the quality and innovation of insulation materials play a decisive role in determining battery performance and safety.

Lankwitzer, a leading company in the field of battery coatings, has been at the forefront of innovation in insulation material for battery cells. At the 3rd eic Three - Electric and Energy Storage “Insulation, Flame Retardancy, Heat Insulation, and Sealing” Technology Conference in 2024, Lankwitzer showcased its latest insulation solutions for battery cells. The company’s representatives shared insights into their ongoing research and development efforts, emphasizing their commitment to meeting the stringent requirements of the battery market.

Lankwitzer’s Evoprotect455UV series is a prime example of its innovative insulation material for battery cells. Evoprotect455UV (UE55 - 0500/0), developed over three years, 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 applied on 24 cell - coating production lines in Germany and China, coating more than 500 million battery cells. This extensive application demonstrates its reliability and stability.

Evoprotect455UV (UE55 - 0500/7), another product in the series, was developed in 2023. Even after 1,000 hours of 85/85 aging tests, it still meets customized customer requirements. It features 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. These excellent performance parameters effectively enhance the safety and durability of battery cells.

Lankwitzer’s insulation material for battery cells offers multiple advantages. In terms of production efficiency, the UV - curing technology enables the coating to solidify in less than 5 seconds, with a production cycle that can meet 50 - 60 ppm. This significantly shortens the production cycle and reduces time costs. In terms of environmental protection and cost control, the coatings have 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, meeting strict environmental standards.

In the EV industry, Lankwitzer’s insulation material for battery cells has been proven effective. In a cooperation project with a well - known automaker, the battery module equipped with Lankwitzer’s insulation coatings maintained a capacity retention rate of over 85% after 5,000 charge - discharge cycles, far exceeding the industry average. This significantly improves the endurance and service life of EVs.

Moreover, Lankwitzer’s Shanghai Testing Center is equipped with a full - process spraying line, providing customized spraying services. This helps customers save the investment in building a trial - production line and accelerates the implementation of technologies.

Thanks to its continuous innovation, Lankwitzer has provided insulation material for battery cells 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 battery industry continues to develop, Lankwitzer’s innovation in insulation material for battery cells will further drive the industry forward.
