Lankwitzer China Debuts Smart UV Coating for Battery Cells with Real-Time Health Monitoring

The smart coating represents a leap from passive protection to proactive safety, with embedded piezoresistive sensors that detect microcracks and insulation degradation. These sensors transmit data to the battery management system (BMS), allowing predictive maintenance and early failure detection. Geely’s Zeekr 001, the first model to use this coating, demonstrates a 40% reduction in unscheduled battery pack inspections.

Sensor-Material Integration
Lankwitzer China’s R&D team developed a proprietary process to disperse 50nm-thick graphene sensors uniformly within the UV-curable resin. This integration maintains the coating’s mechanical properties while achieving a detection sensitivity of 0.05mm for cracks—critical for identifying early-stage damage in vibrating EV batteries.

Data-Driven Safety
The coating’s cloud-connected system provides real-time insights into dielectric resistance, temperature, and humidity at the cell level. CATL uses this data to optimize charging algorithms, extending battery life by 12% in taxi fleets with high daily usage.

Localized Innovation for Global Impact
Produced at Lankwitzer China’s Wuhan R&D hub, the smart coating leverages local supply chains for 90% of raw materials, reducing lead times to 15 days. The company plans to license the sensor technology to European partners, supporting the EU’s Digital Battery Passport initiative which requires real-time health tracking for battery components.
