HowTo

Insert up to five pouch cells into the five-layer grid structure and adjust the thickness gap to match cell dimensions. Tighten the single-nut locking configuration to achieve uniform face-to-face compression at 450 kg baseline pressure.

Required Equipment: ATM-PCBT-316SS-5L Fixture, Torque wrench or hand tool for nut tightening

Insert pouch cells
Insert up to five multi-layer pouch cells into the five-layer grid structure, ensuring proper alignment within the clamping area.
Adjust thickness gap
Set the adjustable thickness gap between 0.1 cm and 3.5 cm to accommodate the specific cell dimensions.
Tighten the single nut
Rotate the single-nut locking mechanism to apply uniform compression, targeting 450 kg baseline pressure and never exceeding 700 kg.
Route sensor cables
Route all sensor signal cables neatly through standard sealing ports before closing the climate chamber.
Verify pressure uniformity
Confirm that the die-spring displacement buffer array maintains consistent face-to-face compression across all layers.

FAQ

How does the single-nut locking configuration achieve uniform pressure across all five layers without localized stress concentrations, and what is the maximum working pressure range?

The single-nut locking configuration works with integrated die-spring displacement buffer arrays to deliver 100% uniform face-to-face compression across all five grids, completely suppressing physical cell thickness swelling. The standard working pressure is 450 kg, with a customizable structural load limit up to 700 kg, optimized by the single nut design to eliminate localized stress concentrations.

What pouch cell dimensions and thickness ranges are compatible with the ATM-PCBT-316SS-5L, and can the fixture be deployed inside climate chambers?

The fixture supports adjustable thickness from 0.1 cm to 3.5 cm, and the size matrices accommodate cell dimensions up to 38×120×150 mm (for the 10×150×180 mm variant). The fixture is compatible with climate chambers; when deployed, ensure all sensor signal cables are routed neatly through standard sealing ports.

What operational limits must be observed to prevent spring fatigue or calibration offsets in the die-spring displacement buffer array?

Do not exceed the maximum theoretical structural load limit of 700 kg (customizable) to prevent spring fatigue or calibration offsets. The die-spring displacement buffer array is designed for five-layer synchronous clamping, and exceeding this limit may cause permanent deformation or loss of pressure uniformity.

Assessment

The ATM-PCBT-316SS-5L is a five-layer pouch cell cycle test fixture machined from premium 316 stainless steel, featuring a single-nut locking mechanism and die-spring buffer arrays to deliver uniform compression across up to five cells simultaneously. Available in seven size variants with maximum loads from 450 to 700 kg, it is designed for corrosion-resistant multi-cell cycling under aggressive electrolyte environments.

Positive

316 Stainless Steel Corrosion Resistance: The fixture is constructed entirely from premium-grade 316 stainless steel, providing optimal resistance to electrolyte vapors, splashes, and acid-alkali environments, making it suitable for aggressive pouch cell cycling tests.
Uniform Compression via Single-Nut Locking: The single-nut locking mechanism combined with die-spring displacement buffer arrays ensures 100% uniform face-to-face compression across all five layers, suppressing cell thickness swelling variables during cycling.

Trade-offs

Load Capacity Limited by Size Variant: The maximum structural load varies by size: smaller variants (e.g., 10×78×105 mm) are rated at 450 kg, while larger variants (≥10×120×160 mm) support up to 700 kg. Selecting an undersized fixture for high-pressure tests risks exceeding the load limit and causing spring fatigue or calibration drift.
Cable Routing Requirement in Climate Chambers: When used inside climate chambers, all sensor signal cables must be routed through standard sealing ports to maintain chamber integrity and avoid interference, adding a setup constraint.
