Application of Kitronyx's Pressure Distribution Measurement System for Secondary Battery Probes
Purpose
Secondary battery cells undergo a series of quality inspections before final assembly into modules or packs. In charge/discharge testing, accurate electrical contact between the probe and the cell is crucial.
To quantify and optimize the contact condition, we conducted tests using Kitronyx’s PressureScan II system. By placing the pressure mapping sensor on a jig and applying the probe under actual conditions, we visualized the pressure shape in real time and quantified uniformity of the pressure applied.
Results
1. Key Outcomes – Quantitative Data Acquisition
The experiment yielded detailed quantitative data, including:
•Active Area (contact size)
•Pressure Distribution Patterns
•Standard Deviation (STDEV)
•Center of Force (COF)
These indicators enabled precise evaluation of contact consistency and localized pressure variation between the probe and the cell.
2. Sensor Performance Comparison – Spatial Resolution
•TFM3000 offers significantly higher resolution than SFM6000CXR2, capturing more localized variations across the same area.
•Due to this finer resolution, TFM3000 tends to produce higher STDEV values, which is a natural result of its sensitivity to minute pressure differences.
Therefore, direct numerical comparisons between sensors with different resolutions should be avoided. It's recommended to select and benchmark sensors appropriate to the process requirements.
3. Customer Preference & Evaluation
For this project, the customer preferred the TFM3000 due to the need to inspect uniformity in battery probes that feature fine pin structures. The sensor's high spatial resolution clearly highlighted pressure concentration zones caused by individual pins — a feature not as prominently observed with the SFM6000CXR2.
This confirmed that TFM3000 is more suitable for applications requiring detailed analysis of pressure uniformity over small contact areas.
⚠️ Note: A high-resolution sensor is not always the optimal choice for every process. Sensor selection should align with process goals and quality control criteria
Expected Benefits and Applications
Detailed Quantification of Microstructures
Enabled precise evaluation of force concentration over micro-sized structures.
Data-Driven Optimization
The acquired data supports the establishment of optimized inspection parameters and quality standards.
Process Automation & Smart Manufacturing
When used in conjunction with ForceLAB2’s OK/NG auto-judgment feature, the system enhances data handling and decision-making efficiency, enabling:
•Automated inspection
•Improved traceability
•Quality-driven process improvements
Kitronyx supports smart manufacturing innovation through process-specific solutions and hands-on field support, developed based on actual operational requirements.
