Advanced Battery Electrode Coating Thickness Measurement Systems

Lithium-ion battery electrodes typically range from 50 to 200 microns in thickness, depending on the battery chemistry and application. Cathode coatings are often 80-150 microns, while anode coatings range from 60-120 microns. Our M-Ray systems can accurately measure across this entire range with micron-level precision.

The coating factor (also called loading density) refers to the mass of active material per unit area on the electrode, typically expressed in mg/cm². It directly relates to coating thickness and material density. Our systems measure thickness in real-time, which when combined with material density data, enables precise coating factor monitoring and control.

Contactless measurement prevents damage to delicate electrode coatings and enables continuous, real-time monitoring without disrupting production flow. Physical contact measurement methods can damage the coating surface, alter thickness readings, or introduce contamination—all critical concerns in battery manufacturing.

M-Ray technology uses millimeter waves instead of ionizing radiation, eliminating safety concerns and regulatory requirements associated with X-ray systems. It's completely non-nuclear and non-radioactive, allowing 24/7 operation without special licensing, shielding, or operator safety protocols while delivering comparable accuracy.

Yes, our systems can be configured with dual-sided measurement capabilities to monitor coating thickness on both sides of the current collector foil simultaneously. This is essential for double-sided electrode production and ensures balanced coating application critical for battery performance.

Our systems operate at multi-kHz measurement rates, enabling accurate thickness measurement at production line speeds up to 500 meters per minute. This high-speed capability ensures comprehensive coverage even in high-throughput battery electrode manufacturing operations.

Our measurement platforms feature Industry 4.0 connectivity with standard industrial communication protocols. They provide real-time data to your production control systems, enabling closed-loop feedback to coating equipment. The IoT app allows remote monitoring and analytics from any location.

Installation typically requires 1-2 weeks depending on system complexity and line configuration. This includes mechanical installation, electrical integration, system calibration, operator training, and validation testing. We work closely with your team to minimize production downtime during installation.
