Product News: Honeywell’s Optical Caliper Measurement Sensor

Promises to measure total thickness of electrode material during coating and pressing operations, boosting lithium ion battery performance.

Honeywell announced the introduction of an Optical Caliper Measurement Sensor designed to optimize lithium ion battery (LIB) production. The new sensor provides an effective solution for measuring the true thickness of electrode material during coating as well as at the pressing station during LIB manufacturing, according to its maker, which notes that accurate thickness measurement is a key criterion for optimal battery performance.

The Honeywell LIB Optical Caliper Sensor uses novel displacement-measurement technology to measure total thickness of coatings. This technique provides one-micron measurement accuracy and enables operators to detect and classify defective areas in the electrode material prior to downstream processing. Honeywell’s solution also promises seamless integration of the measurement platform with advanced controls and a web-based Human-Machine Interface (HMI).

“Honeywell’s LIB Optical Caliper Sensor is proven to measure the total thickness of the electrode material from edge to edge and provides precise data that can be used as a control feedback, thus helping to optimize the thickness of the sheet material,” said Fredrik Westerberg, director, strategic planning, Honeywell Process Solutions. “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.” 

With the addition of the LIB Optical Caliper Sensor to its family of gauging products, Honeywell can provide a complete, integrated solution for end-users and Original Equipment Manufacturers (OEMs) in the LIB manufacturing industry, they claim.
