Coating thickness gauge

stationarynon-contactin-line

Overview
The X-ray 100% measurement system is a high-precision, non-contact inline solution for continuous monitoring of cathode coatings on battery electrodes. It continuously measures surface density across the full web width, detects edge-thinning and local thin spots, and stores all measurement data for complete traceability. The patented Reechi detection specifically identifies edge/thinning areas that conventional methods often miss, enabling targeted process control and better lifetime performance of lithium-ion cells.

Product highlights

• Full-width measurement across the entire web
• Complete data traceability for each electrode
• No traversing required — true 100% inline measurement

Customer benefits

• Immediate detection of coating defects and thin spots
• Faster response to process deviations through real-time feedback
• Reduced scrap rates and lower production costs
• Comprehensive documentation and traceability of coating quality

Applications
Complete control of surface density for cathode coatings during lithium‑ion battery cell production; detection and monitoring of edge thinning zones; 100% inspection during winding, slitting and roll-to-roll processes.
