XianXiang Zhongke Science & Technology Co. Ltd Purchases NDC FG710S Sensor to Measure Thickness of Battery Separator Film
“Our conclusion is that only NDC’s FG710S infrared sensor can accurately measure the actual thickness of our lithium ion battery micro-porous films. This unique solution surpasses anything else in the business”
Mr. Pang Jinsen, General Manager, Xinxiang Zhongke Science & Technology Co. Ltd.

To produce uniform LIB separator film, Zhongke decided that it needed to accurately measure and control the thickness. LIB film thickness is important because if the film is too thin or porous, then a battery will discharge quickly with the risk of overheating or worse, catching fire. If the film is too thick, then a battery will underperform. Zhongke’s program involved evaluating three very different measurement technologies to determine the best solution for measuring the thickness of their LIB separator films. Their objective was to select a high-technology gauging supplier to measure and control the thickness of their separator films and help improve battery quality in terms of safety and performance. |

Thickness or Weight Measurement?
Zhongke purchased and evaluated web gauging equipment from three different companies, each with distinctly different measurement technologies. NDC supplied its unique infrared FG710S direct thickness sensor, while the other two companies delivered their transmission x-ray and beta sensor technologies. Direct thickness measurement is especially important for micro-porous film products, as any non-uniform stretching on the line can produce micro-porous “gradients” resulting in thickness and density variations.
During the evaluation process, Zhongke concluded that the x-ray and beta sensors could only measure the total mass of their LIB films and not the thickness. This was because the micro-pores within the film structure resulted in thickness variations that these traditional technologies were unable to detect.
The Solution: FG710S Unique Thickness Measurement
What is unique about the FG710S is its ability to compute the true thickness of LIB film by measuring both the transmitted light passing through the film and the light scattered by the micro-pores using specific near infrared wavelengths. The FG710S combines these two values, with its patented optical engine and powerful sensor algorithms providing fast, accurate thickness measurement for micro-porous films. This has translated into distinct quality and production improvements for Zhongke’s LIB film.
Delivering the Results: Advanced Profile Control
In addition, Zhongke were impressed with NDC’s automatic profile control (APC). The combination of accurate thickness measurement plus APC control has provided far more stable control resulting in flatter, more uniform film. As a result, Zhongke has now standardized on NDC’s web gauging systems for its other LIB film separator lines.
