Honeywell Solutions for Lithium Ion Battery Manufacturing

Optical Caliper Sensor 
For Manufacturers of LIBs, the coating and pressing sections of the battery manufacturing line have demanding requirements. It is particularly important to produce electrode sheets with a uniform coating on the top and bottom sides of the material.

The Honeywell LIB Optical Caliper Sensor uses novel displacement measurement technology to measure total thickness of coatings. This technique provides sub-micron measurement accuracy and enables operators to detect and classify defective areas in the electrode material prior to downstream processing.

The sensor’s high-precision measurements are key to producing uniform electrode material, reducing scrap and increasing battery production yield. This capability differs from current practices where electrode defects only become observable further down-stream in the process – often resulting in expensive wastage, rejects and reduced production yield.
