Description

ATOMFAIR® ATM-PCBT-SS-4L STAINLESS STEEL BATTERY CYCLE TEST FIXTURE

RESEARCH GRADE MATERIAL

Product Overview
The ATOMFAIR® electrochemical engineering matrix introduces a high-capacity battery cycle test fixture meticulously optimized to support continuous expansion profiling under precise, uniform force fields. Specifically developed for academic professors, Ph.D. electrochemists, and corporate battery testing labs, this heavy-duty ATM-PCBT-SS-4L Stainless Steel multi-tier jig enables seamless tracking of pouch configurations. Upgraded into an optimized architectural framework, it embeds high-fidelity electronic transducer nodes to establish instant real-time pressure monitoring throughout prolonged cycling validation matrices. Utilizing an advanced, streamlined single nut locking alignment assembly, the layout mitigates internal shear stress gradients, successfully eliminating active material wrinkling or trace signal noise during characterization.

Key Features & Advantages
  • Technical Advantage: Upgraded four-layer synchronous clamping architecture expands testing capacity, supporting the insertion of thicker battery nodes or multiple cells simultaneously.
  • Technical Advantage: Integrated internal inline electronic transducer interface outputs reliable telemetry data curves via standard output pins for real-time monitoring.
  • Technical Advantage: Specialized single-nut closure join, backed by high-rebound die spring buffers, balances mechanical loading profiles up to 600kg and protects delicate pouch surfaces against scratches.
  • Technical Advantage: Rigid stainless steel configuration delivers top-tier structural corrosion and wear resistance, facilitating simple cleaning and maintenance in standard or abusive leakage testing setups.

APPLICATION SCOPE: Long-term volumetric swelling analysis of multi-layer pouch cell battery chemistries, high-pressure galvanostatic cycle life profiling, multi-cell high-throughput research setups, harsh electrolyte immersion/leakage testing, and laboratory cleanroom validation matrices.
PACKAGING: Dispatched safely inside heavy-duty, reinforced storage boxes. Each individual assembly unit comes fully equipped with the selected four-layer stainless steel plates, 1x calibrated transducer sensor with link cabling, matching precision die springs, and single nut lock components.
IMPORTANT NOTICE: Built strictly for laboratory testing and prototyping configurations in professional research locations. Abide by the dimensional rule: maximum cell width and length must remain ≤ fixture parameters minus 30 mm to preserve proper edge clearing boundaries. Route data links away from high electromagnetic interference arrays to guarantee uncompromised trace readout accuracy.

The fixture imposes maximum working pressure limits of 400 kg to 600 kg depending on size, with a compatible battery thickness range of 0.1–2.5 cm. Material selection between 304 and 316 stainless steel determines corrosion resistance and load-bearing capacity in electrolyte-exposed environments.

  • Pressure Limits: Exceeding the rated working pressure may cause structural deformation or failure of the four-layer assembly.
  • Material Compatibility: Stainless steel grades 304 and 316 offer different resistance to acidic or alkaline electrolyte leakage.
  • Cell Size Constraints: Maximum cell length and width must be at least 30 mm less than the fixture’s internal dimensions to ensure proper alignment and clamping.
  • Uniform Pressure Requirement: The single nut design requires even torque application across all four layers to maintain pressure distribution and avoid localized stress.
  • Customization Limits: Custom fixture sizes, layer spacing, and surface treatments must remain within the structural load capacity of the stainless steel assembly.

This fixture clamps pouch cells under controlled pressure for cycle testing while the pressure sensor monitors real-time load. Correct assembly ensures uniform force distribution and prevents cell damage or sensor misreading.

Required Equipment: Torque wrench or calibrated nut driver

  1. Prepare the fixture
    Inspect all four layers for cleanliness and confirm the die spring and pressure sensor are properly seated.
  2. Position the cell
    Place the pouch cell centrally between the stainless steel layers, ensuring it does not protrude beyond the fixture boundaries.
  3. Tighten the single nut
    Turn the single nut gradually until the die spring compresses and the target working pressure (400 kg or as specified) is displayed on the pressure sensor.
  4. Verify uniform clamping
    Check that all four layers move synchronously and the pressure reading remains stable across the sensor.
  5. Connect test leads
    Attach battery cycle test leads to the pouch cell tabs, ensuring no short circuits or mechanical stress on the connections.
  6. Monitor during cycling
    Observe the pressure sensor output continuously and adjust the nut if the pressure drifts outside the acceptable tolerance.

How does the material choice (304 vs 316 stainless steel vs aluminum vs plastic) affect the maximum working pressure and corrosion resistance of the ATM-PCBT-SS-4L pouch cell fixture?

The standard working pressure is 400 kg, customizable up to 600 kg for stainless steel and carbon steel. 304 and 316 stainless steel offer high load-bearing capacity and corrosion resistance, with 316 providing superior acid/alkali resistance for harsh environments like leakage testing. Aluminum alloys (7075-T6, 6061-T6) are lightweight but lower strength; PP/HDPE and PEEK are ultra-lightweight and fully electrolyte-resistant but suited for low-pressure testing only. Carbon steel provides lowest cost with strong load-bearing for high-pressure applications.

What is the maximum compatible cell size for the ATM-PCBT-SS-4L fixture, and how is it determined?

Maximum cell length and width equal fixture length and width minus 30 mm. For example, a 150×180 mm fixture accommodates cells up to 120×150 mm with thickness ≤ 28 mm for the 10*150*180 variant or ≤ 26 mm for the 12*150*180 variant. The four-layer spacing is adjustable to support cell thicknesses from 0.1 to 2.5 cm, allowing testing of thicker batteries or multiple batteries simultaneously.

Does the integrated pressure sensor require any special calibration or setup before use, and how does the single nut design ensure uniform pressure?

The pressure sensor is an essential structural component built into the four-layer fixture, enabling real-time pressure monitoring without additional calibration steps. The single nut locking mechanism combined with a die spring buffer ensures uniform pressure distribution across all four layers, eliminating the need for external pressure distribution plates. The standard working pressure is 400 kg (customizable up to 600 kg), and the fixture size, layer spacing, and pressure level can be customized per test requirements.

The ATM-PCBT-SS-4L four-layer stainless steel fixture incorporates a built-in pressure sensor and single nut clamping mechanism to deliver uniform pressure distribution for pouch cell cycle testing, with customizable working pressure up to 600 kg. Operational constraints include a mandatory 30 mm size margin between cell and fixture dimensions, and the need to specify 316 stainless steel for aggressive electrolyte environments.

Positive

  • Single Nut Uniform Pressure Distribution: The single nut locking mechanism combined with die spring buffer provides uniform pressure distribution across the four-layer structure, enhancing test reproducibility and reducing localized stress on pouch cells.
  • Integrated Pressure Sensor for Real-Time Monitoring: An integrated pressure sensor allows continuous monitoring of applied force during cycling, enabling precise control and data correlation for battery performance analysis.

Trade-offs

  • Mandatory Size Margin Requirement: Cells must be at least 30 mm shorter in length and width than the fixture dimensions, limiting compatibility with larger-format pouch cells that approach plate boundaries.
  • Material Sensitivity to Harsh Electrolytes: The standard 304 stainless steel offers general corrosion resistance but is not recommended for aggressive electrolyte leakage or immersion testing; upgrade to 316 stainless steel is required for such harsh environments.
