In-situ expansion analysis system

The In-situ Expansion Analysis System is designed for high-precision measurement of dimensional and volumetric changes in electrochemical cells and related materials during charge/discharge, storage, and abuse testing. The system enables real-time, non-destructive monitoring of cell expansion behavior under controlled temperature, pressure, and environmental conditions. It is widely used in lithium-ion, solid-state battery R&D, safety evaluation, and reliability testing.

Application

(1) In-situ expansion and swelling analysis of lithium-ion pouch, prismatic, and coin cells during charge/discharge cycles.

(2) Dimensional change monitoring of solid-state batteries and solid electrolytes under electrochemical loading.

(3) Thermal expansion and contraction testing under wide temperature ranges for battery reliability studies.

(4) Pressure-coupled expansion analysis for pouch cell fatigue and mechanical stability evaluation.

(5) Correlation analysis between expansion, voltage, cycle life, and degradation mechanisms.

(6) Abuse and reliability testing including overcharge, fast charging, and thermal stress conditions.

Standards

(1) ASTM E83 – Standard Test Method for Verification of Linear Displacement Measuring Systems.

(2) ISO 12417-1 – Mechanical Testing of Metals – Dilation Test.

(3) IEC 62660-2 – Secondary lithium-ion cells for propulsion of electric road vehicles – Reliability and abuse testing.

(4) DIN 51221 – Testing of adhesives – Determination of tensile shear strength (dimensional deformation reference).

(5) CE Certification – Conformité Européenne.

Features

(1) Sub-micron displacement resolution down to 0.01 μm for precise expansion measurement.

(2) Non-contact laser displacement sensors eliminate mechanical interference and measurement hysteresis.

(3) Multi-environment testing with integrated temperature chamber covering –40°C to 200°C.

(4) Dynamic pressure loading up to 50 bar for pouch cell fatigue and mechanical stress testing.

(5) Real-time 3D deformation imaging with structured light scanning technology.

(6) AI-assisted deformation analysis for quantification of anisotropic and localized swelling.

(7) Multi-channel architecture supporting up to 8 cells tested simultaneously.

(8) Automatic test sequencing with preloaded protocols for common battery test scenarios.

(9) Open data interface for synchronization with EIS, gas analysis, and thermal imaging systems.

Test Procedures

(1) Install the test cell into the appropriate sample holder and align using the laser positioning system.

(2) Configure test parameters including temperature profile, pressure loading, channel selection, and data acquisition rate.

(3) Connect the system to external electrochemical testers if synchronized testing is required.

(4) Start the test sequence; the system records displacement, temperature, pressure, and auxiliary signals in real time.

(5) Monitor expansion behavior during testing and export data for further analysis and reporting.

Maintenance Information

(1) Regularly inspect laser sensors, optical components, and mechanical fixtures for contamination or misalignment.

(2) Perform periodic calibration using certified displacement standards.

(3) Check temperature chamber seals, pressure components, and safety interlocks routinely.

(4) Keep optical windows and sensor surfaces clean to maintain measurement accuracy.

(5) Update software and back up data according to laboratory quality management requirements.
