CNC Machined Parts for Battery Cell Swelling Testing Details
We provide professional battery cell swelling test fixture solutions for lithium-ion battery R&D, validation, and testing applications. The fixture is designed to apply controlled mechanical compression to the cell during charge and discharge cycles, while accurately measuring swelling behavior, including thickness change and expansion force.
Unlike standard off-the-shelf fixtures, we focus on custom engineering and application-specific solutions. Whether you are working with prismatic cells or pouch cells, we can design and manufacture fixtures tailored to your cell format, test conditions, and project requirements.
What We Help You Solve
Accurate and repeatable swelling data is critical in battery development. However, many test setups fail to replicate the real mechanical constraints found in battery packs, and standard fixtures often cannot accommodate different cell sizes or testing conditions.
Our solution ensures that cells are tested under stable and controlled mechanical conditions. With integrated sensor compatibility, we enable synchronized measurement of displacement, force, and temperature, significantly improving data reliability and consistency.
Our Engineering Capabilities
We offer more than just a fixture—we provide full engineering support from concept to delivery.
Based on your cell specifications and test requirements, we develop customized fixture structures and optimize them through mechanical simulation, ensuring uniform force distribution and structural rigidity. With high-precision 5-axis CNC machining, we achieve excellent dimensional accuracy and assembly consistency. Surface treatments such as anodizing enhance durability and long-term stability. All critical components can be verified using CMM (Coordinate Measuring Machine) inspection to ensure quality and reliability.
Key Features
The fixture features a high-rigidity structure that maintains stability under long-term loading, ensuring consistent test results. The compression force is adjustable to simulate real-world pack conditions, and the design is compatible with multiple cell formats. It also supports integration with displacement sensors, load cells, and temperature monitoring systems, making it easy to build a complete testing setup.
Applications
This fixture is suitable for a wide range of battery testing scenarios, including cell swelling evaluation, thickness expansion measurement, and swelling force testing. It is also widely used in cycle life testing, high-temperature and overcharge testing, and battery pack structural validation. Typical applications include EV battery development and energy storage systems (ESS).
Customization
We offer flexible customization based on your specific needs. This includes adapting to different cell sizes and formats (prismatic or pouch), designing compression structures and loading methods, developing multi-channel test fixtures, and integrating sensor solutions for displacement, force, and temperature measurement.
