Pouch Cell Cycle Test Fixture 5-Layer 500–800 kg ATOMFAIR®

ATM-PCBT-CS-5L POUCH CELL CYCLE TEST FIXTURE

RESEARCH GRADE MECHANICAL EQUIPMENT

Product Overview

The ATM-PCBT-CS-5L is a high-rigidity, cost-optimized heavy-duty mechanical split test clamping tool engineered for the high-pressure parallel electrochemical evaluation of up to 5 multi-layer pouch cell batteries simultaneously. This robust system features an upgraded five-layer structural carbon steel grid configuration controlled by a single-nut central locking regulation mechanism and high-load die-spring displacement buffer arrays, successfully delivering 100% uniform face-to-face compression while completely suppressing physical cell thickness swelling variables under massive forces. Finished with an industrial-grade anti-wear and rust-proof coating to ensure long-term physical alignment and eliminate metal flex, it features an elevated standard working face pressure of 500 kg (customizable up to 800 kg Max. heavy-load theoretical threshold) and features an adjustable physical gap boundary layout perfectly supporting cells from 0.1 cm up to 3.5 cm.

FAQ

What are the performance trade-offs between the default carbon steel and the 7075-T6 aluminum alloy material options for the ATM-PCBT-CS-5L fixture?

The default carbon steel offers the lowest cost and strong load-bearing capacity for cost-sensitive high-pressure testing, while the 7075-T6 aluminum alloy provides lighter weight, the highest strength among aluminum alloys, insulation after anodizing, and the capability for real-time pressure monitoring via a built-in pressure sensor, making it more suitable for precision cycle testing. The trade-off is between cost and load capacity versus precision, weight, and monitoring capability.

Can the ATM-PCBT-CS-5L fixture be used with pouch cells that may leak electrolyte, and which material option is best for such immersion testing?

Yes, the fixture can be used for leakage/immersion testing by selecting an appropriate material option. The 316 stainless steel variant provides optimal electrolyte corrosion resistance and is specifically suitable for harsh testing scenarios involving electrolyte contact. PP and PEEK are also fully electrolyte-resistant with no swelling, while the default carbon steel is not recommended for electrolyte exposure.

What are the critical handling and environmental requirements to maintain long-term alignment accuracy of the ATM-PCBT-CS-5L fixture?

To maintain long-term alignment accuracy, avoid operating the fixture in open moisture environments unless enclosed in a desiccated containment box. The structural load must never exceed the extreme 800 kg ceiling to prevent mechanical deformation. The industrial-grade anti-wear and rust-proof coating provides protection against wear but does not eliminate the need for controlled humidity conditions.

Assessment

The ATM-PCBT-CS-5L is a rigid five-layer carbon steel split test fixture for simultaneous high-pressure cycling of up to five pouch cells, featuring a single-nut locking mechanism for uniform compression and die-spring buffers for swelling suppression, but limited to 800 kg maximum load and requiring dry operation to maintain alignment.

Positive

Uniform high-pressure distribution: Single-nut locking configuration combined with die-spring displacement buffer arrays delivers 100% uniform face-to-face compression across all five layers, eliminating localized stress and physically suppressing cell thickness swelling.
Simultaneous multi-cell throughput: The five-layer structural carbon steel grid allows parallel testing of up to five pouch cells with adjustable thickness from 0.1 cm to 3.5 cm, maximizing experimental throughput per fixture.

Trade-offs

Strict load ceiling of 800 kg: The maximum heavy-load theoretical threshold is 800 kg; exceeding this limit risks permanent mechanical deformation and loss of alignment accuracy, imposing a hard upper bound on test pressure.
Moisture sensitivity for long-term alignment: To maintain long-term alignment accuracy, the fixture must not be operated in open moisture environments unless enclosed in a desiccated containment box, adding infrastructure requirements for humid lab conditions.
