As electric vehicles (EVs) demand higher energy densities, insulation material for battery cells has become a critical safety component. Lankwitzer’s new solution combines aerogel nanoparticles with UV-curable polymers, creating a flexible yet robust barrier that withstands temperatures exceeding 1,000°C. 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’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. Tesla’s 4680 battery cells, now using this insulation, demonstrate 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 Tesla’s Gigafactory throughput by 30%, while energy consumption per cell drops by 70%. Lankwitzer’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 CO? extraction aligns with EU Battery Passport requirements. Lankwitzer’s new 1,600 m2 facility in Osterwieck, set to open in late 2025, will triple production capacity, targeting 50% of global EV battery insulation material market share by 2030.
