Lankwitzer Revolutionizes EV Battery Safety with Advanced Application UV Coating

As the EV market accelerates, the application UV coating has emerged as a critical technology for addressing battery challenges like thermal runaway, electrical shorting, and environmental corrosion. Lankwitzer’s EvoProtect455UV series sets the benchmark, offering rapid-curing, high-adhesion coatings that form a robust protective layer on battery cells, separators, and connectors.

In 2025, Lankwitzer launched the EvoProtect455UV (UE55-0500/7), a next-generation application UV coating developed in collaboration with CATL for 800V high-voltage platforms. This solution delivers a dielectric strength of 150kV/mm and a thermal conductivity of 0.12W/m·K, effectively isolating cells while dissipating heat during fast charging. Its 5B-level adhesion ensures long-term stability in extreme conditions, as validated by tests in NIO’s ET7 battery packs, where it reduced thermal runaway incidents by 40%.

Lankwitzer’s technical advantage lies in its nanocomposite formulation, integrating boron nitride nanosheets to create a three-dimensional insulation network. This design enhances chemical resistance to electrolytes and mechanical resilience to vibrations, critical for EVs navigating rough terrains. The company’s AI-driven R&D platform in Shanghai reduces coating development time by 30%, enabling rapid customization for clients like Tesla, which uses the technology in its 4680 cylindrical cells.
