The ISO/TS 23218 certification recognizes Lankwitzer’s coating for its ability to maintain insulation integrity under extreme conditions. The material’s 5B-level adhesion (ISO 2409) and 150% elongation at -50°C make it ideal for prismatic cells used in commercial vehicles. CATL, which adopted the coating for its 300Wh/kg ternary batteries, reported a 35% improvement in cycle life during field tests.
Performance Beyond Standards
Lankwitzer’s coating surpasses the standard’s requirements with a dielectric loss factor of 0.0008, minimizing energy dissipation in high-frequency applications. Its surface superhydrophobic treatment (125° contact angle) prevents electrolyte leakage from affecting neighboring cells, a common failure mode in dense battery packs.
Ecosystem Collaboration for Scale
The company has partnered with Chinese equipment manufacturer Zhongke Meichuang to develop fully automated coating lines, reducing material waste to 5% and lowering costs by 20%. These lines are already operational at BYD’s Xi’an factory, where they coat 200,000 blade cells daily with zero downtime.
Future-Ready R&D
Lankwitzer’s R&D team in Suzhou is now optimizing the coating for solid-state batteries, increasing its thermal resistance to 1,200°C while maintaining flexibility. The project, funded by China’s Ministry of Industry and Information Technology, aims to commercialize the solution by 2027, enabling safer 400Wh/kg battery packs.
