Application of Kitronyx's Pressure Distribution Measurement System for Secondary Battery Cell Thickness Inspection.
Purpose
The thickness of secondary battery cells plays a critical role in determining both performance and safety. If the cell thickness is inconsistent, it can lead to reduced battery life or, in severe cases, safety issues such as overheating. For this reason, precision thickness inspection is a vital part of the post-production quality control process.
In particular, thickness inspection equipment that directly contacts the cell must apply pressure uniformly across the surface. Any non-uniform pressure or structural unevenness can lead to inaccurate measurements. Therefore, verifying the uniformity of pressure application is essential to ensure the reliability of the inspection equipment.
Kitronyx’s pressure mapping sensors are extremely thin and flexible, allowing them to be inserted directly into inspection equipment. They enable precise visualization of pressure distribution at the contact interface. With real-time measurement, quantitative analysis, and data logging capabilities, the system significantly improves inspection reliability.
For these reasons, the customer chose to replace conventional pressure indicating films with Kitronyx’s PressureScan II system to evaluate pressure uniformity and strengthen quality control across their process.
Results
Comparison of Pressure Uniformity Measurements: Pressure Indicating Film vs. PressureScan II
The image below illustrates a comparison of pressure uniformity measurements on the same equipment, conducted by the customer using two different methods: conventional pressure indicating film and Kitronyx’s PressureScan II.
When using pressure indicating film, it was difficult to clearly identify which areas were subjected to higher or lower pressure. The pressure distribution and intensity could not be precisely interpreted, and no quantitative data could be obtained.
In contrast, when using PressureScan II, regions of high and low pressure were clearly distinguishable through differences in color intensity. Furthermore, the system enabled pressure distribution to be quantified in real time, providing numerical data for objective analysis.
Why the Customer Replaced Pressure Indicating Film with PressureScan II
Conventional pressure indicating films (e.g., LW, LLW types) must be selected and replaced according to the target pressure range. A single film type cannot cover a wide range of pressures, which often leads to issues such as incomplete pressure patterns or inaccurate readings when a mismatched film is used.
In addition, pressure films are prone to contamination during handling or installation—such as smudging from finger contact or environmental factors—which may distort results. Most importantly, since they only provide a static image of the pressure shape, they do not allow for quantitative or objective analysis of pressure uniformity.
In contrast, PressureScan II supports a significantly broader pressure range with a single sensor and enables continuous, real-time measurement. It provides quantitative pressure distribution data, allowing for objective evaluation of pressure uniformity.
The system also allows for immediate data storage and replay, making it possible to observe pressure changes over time. This enables faster, more precise responses across various use cases, such as:
•Equipment condition tuning
•Design optimization
•Early detection of process anomalies
For these reasons, the customer adopted PressureScan II to replace traditional pressure films, aiming to improve pressure uniformity diagnostics and strengthen overall quality control.
Expected Benefits and Applications
Enhancing Inspection Reliability and Preventing Quality Issues with PressureScan II
By utilizing Kitronyx’s PressureScan II, manufacturers can precisely evaluate the pressure conditions within inspection equipment. This leads to improved reliability in battery quality inspections and helps prevent both product defects and potential safety incidents.
In particular, real-time analysis and time-series data management enable early detection of process anomalies, optimization of equipment settings, and enhanced process control. The system is not only effective in the secondary battery industry, but also highly adaptable to various other industries where uniform pressure distribution is critical for quality and performance.
