ESS Cell Coating: Lankwitzer’s Innovative Approach Revolutionizing Energy Storage

In the rapidly expanding energy storage industry, ESS cell coating plays a crucial role. As the world transitions towards renewable energy sources, energy storage systems (ESS) are becoming increasingly important. ESS cell coating serves as a safeguard, protecting cells from environmental factors, preventing short - circuits, and improving overall system efficiency.

Lankwitzer, a prominent company in the battery coating sector, has been at the forefront of innovating ESS cell coating. At the 3rd eic Three - Electric and Energy Storage “Insulation, Flame Retardancy, Heat Insulation, and Sealing” Technology Conference in 2024, Lankwitzer unveiled its latest ESS cell coating solutions. The company’s representatives emphasized their commitment to developing advanced coatings that can meet the unique challenges of the energy storage market.

Lankwitzer’s Evoprotect455UV series has proven to be highly effective for ESS cell coating. 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%, it has been widely adopted on 24 cell - coating production lines in Germany and China. It has coated more than 500 million battery cells, many of which are used in energy storage systems.

Evoprotect455UV (UE55 - 0500/7), introduced in 2023, further demonstrates Lankwitzer’s technological prowess. Even after 1,000 hours of 85/85 aging tests, it still meets customized customer requirements. This coating offers 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 features ensure the long - term stability and reliability of ESS cells.

Lankwitzer’s ESS cell coating solutions offer multiple advantages. The UV - curing technology enables the coating to solidify in less than 5 seconds, with a production cycle that can reach 50 - 60 ppm. This significantly improves production efficiency and reduces manufacturing costs. In terms of environmental protection, the coatings have excellent recycling performance, with a comprehensive utilization rate of up to 95%. They generate almost no volatile organic compounds (VOCs) during the curing process, aligning with strict environmental standards.

In a large - scale energy storage project, Lankwitzer’s ESS cell coatings demonstrated their effectiveness. The energy storage system equipped with Lankwitzer - coated cells maintained stable performance even under extreme weather conditions. After extended use, the system’s capacity retention rate remained high, far exceeding industry benchmarks.

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

Thanks to its continuous innovation, Lankwitzer has provided ESS cell coating for over 450 million commercial battery cells. As the energy storage industry continues to grow, Lankwitzer’s ESS cell coating solutions will continue to drive the industry forward, setting new standards for energy storage performance and reliability.
