PP Pouch Cell Test Fixture 150kg Working Pressure ATOMFAIR®

Description

ATOMFAIR® ATM-PCBT-PP POUCH CELL BATTERY TEST FIXTURE (PP BASIC VERSION)

RESEARCH GRADE MATERIAL

Product Overview

The ATOMFAIR® hardware core matrix delivers an ultra-lightweight battery test fixture engineered to secure stable planar clamping fields during repetitive pouch cell expansion validation. Specifically optimized for academic professors, Ph.D. students, and corporate materials laboratory technicians conducting low-to-medium pressure battery cycle testing routines, this configuration features a premium polypropylene platform. The ATM-PCBT-PP Basic Version architecture features an integrated structural matrix that remains fully electrolyte-resistant to prevent layer swelling or decomposition across demanding trial matrices. Utilizing a symmetric 4-corner screw locking closure backed by linear spring buffers, it provides a gentle clamping interface that completely protects outer laminated cell films from abrasive scratch distortion.

Key Features & Advantages

Technical Advantage: Premium-grade pure polypropylene construction eliminates liquid chemical reactions, preventing dimension distortion or layer swelling.
Technical Advantage: Calibrated 4-corner screw closure combined with high-rebound die spring buffers delivers smooth, symmetric force distribution without sharp stress edges.
Technical Advantage: Soft, non-abrasive material faces safeguard delicate outer pouch current collector tabs and outer films against deep scratches.
Technical Advantage: Highly customizable configuration parameters allow fast tuning of internal spacing heights to accommodate battery thicknesses between 0.1 and 1.5 cm.

APPLICATION SCOPE: Low-to-medium pressure pouch cell battery cycle stability verification, structural expansion tracking, multi-cell high-throughput research rows, aggressive fluid optimization trials, and glovebox/cleanroom routine setups.

PACKAGING: Dispatched safely inside heavy-duty, impact-resistant industrial packing. Each individual assembly unit comes fully equipped with the selected polypropylene plates, matching precision die spring buffers, and corner locking hardware components.

IMPORTANT NOTICE: Materials intended strictly for scientific validation and laboratory prototyping applications. Abide by the structural sizing rule: maximum cell width and length must remain ≤ fixture parameters minus 30 mm to preserve safe clearing boundaries and protect the cell edge seals. Do not apply mechanical loads exceeding the rated 200 kg threshold to prevent structural polymer deformation.

Constraints

This fixture imposes constraints on cell dimensions and clamping pressure to ensure safe and effective battery cycle testing. Material selection must account for electrolyte compatibility to avoid swelling or degradation of the fixture.

Cell Dimension Constraint: The pouch cell must be at least 30 mm smaller than the fixture in both length and width to allow proper alignment and clamping.
Pressure Limitation: Maximum clamping pressure is 200 kg for standard configurations; exceeding this limit may damage the fixture or cell.
Electrolyte Material Compatibility: Polypropylene (PP) and HDPE are suitable for standard electrolyte contact; stainless steel and aluminum alloys require anodization or coating for complete resistance.
Spring Buffer Compliance: The die spring buffer provides compliant force to accommodate cell swelling during cycling, but must be periodically checked for fatigue.

FAQ

How does the choice between PP and 316 stainless steel affect the maximum working pressure and corrosion resistance in the Atomfair Pouch Cell Battery Test Fixture?

The PP version (basic) supports a standard working pressure of 150 kg, customizable up to 200 kg, while 316 stainless steel can handle 0-500 kg. However, PP is fully electrolyte-resistant with no swelling, whereas 316 stainless steel offers the best electrolyte corrosion resistance suitable for leakage or immersion conditions. The trade-off is lower pressure capacity versus superior corrosion resistance for aggressive electrolyte environments.

What is the sizing rule for matching pouch cells to the Atomfair PP test fixture?

The maximum compatible cell dimensions are calculated by subtracting 30 mm from the fixture's length and width. For example, a fixture size of 8*120*160 mm can accommodate cells up to ≤15*90*130 mm. This 30 mm margin ensures safe clamping space and protects the cell from damage during testing.

What handling and safety considerations are important when using the PP version of the pouch cell test fixture under maximum load?

The PP fixture is ultra-lightweight and scratch-proof to protect cell film, but its maximum working pressure is 200 kg, requiring careful tightening of the 4-corner screw locking system. The die spring buffer provides a soft clamping action to prevent cell damage, so ensure the spring buffer is properly engaged before applying full pressure. The fixture should be handled with care to avoid dropping, as PP is tough but can be scratched by abrasive surfaces.

Assessment

The Atomfair PP Basic Version pouch cell test fixture offers an ultra-lightweight, cost-effective solution for medium and low pressure battery cycle testing, with full electrolyte resistance and scratch-proof protection for cell films. It is limited to a maximum 200 kg clamping force and has lower impact resistance than the HDPE option, making it best suited for standard laboratory cycling.

Positive

Electrolyte-resistant PP construction with no swelling: The polypropylene material resists electrolyte attack without swelling, ensuring long-term dimensional stability during cycle testing.
Soft scratch-proof surface protects cell film: The soft PP material avoids scratching the pouch cell film, preserving cell integrity and preventing test artifacts.

Trade-offs

Pressure limited to 200 kg max: The PP fixture is designed for medium and low pressure applications, with a maximum clamping force of 200 kg, restricting its use in high-pressure test scenarios.
Lower impact resistance than HDPE: Compared to the optional HDPE material, the standard PP has lower impact resistance, making it less suitable for tests involving mechanical shocks or rough handling.
