Lankwitzer China Unveils Advanced UV-Curable Coatings for EV Battery Safety

As China’s EV market surpasses 10 million annual sales, Lankwitzer China is accelerating its role as a key supplier of advanced battery materials. Its new UV-curable coatings, designed for pouch and prismatic cells, combine aerogel nanoparticles with UV-curable polymers to create a flexible yet robust thermal barrier. The material’s thermal conductivity of 0.015 W/m·K is 50% lower than traditional PET films, effectively isolating cells during extreme charging cycles.

Aerogel Composite Technology
Lankwitzer China’s proprietary aerogel-resin hybrid matrix forms a three-dimensional thermal barrier, minimizing heat transfer between cells. The material’s nanostructure also enhances flame retardancy, achieving UL94 V-0 certification without halogen additives. BYD’s Blade Battery, now using this insulation, demonstrates a 60% reduction in thermal runaway propagation speed during testing.

UV-Curable Process Advantages
The UV-curable formulation enables rapid manufacturing, with curing times reduced from 20 minutes (traditional epoxy) to 3 seconds. This efficiency boost has already increased BYD’s Nanjing factory throughput by 30%, while energy consumption per cell drops by 70%. Lankwitzer China’s automated coating system ensures uniform 0.1mm thickness, eliminating manual errors common in traditional insulation methods.

Sustainability and Scalability
The material’s 92% recycling rate via supercritical CO₂ extraction aligns with China’s dual-carbon goals. Lankwitzer China’s new 1,600 m² facility in Nanjing, set to open in late 2025, will triple production capacity, targeting 50% of China’s EV battery insulation market share by 2030.
