Key Features & Advantages
  • Four-Layer Structure with Integrated Pressure Sensor: Upgraded from the three-layer design with an additional layer; the pressure sensor is an essential structural component enabling real-time pressure data acquisition via external equipment.
  • Single Nut Locking Design: Delivers more uniform pressure distribution compared to conventional multi-nut configurations, ensuring consistent and reproducible battery cycle test data.
  • Ultra-Lightweight PP Construction: Cost-effective polypropylene material with inherent insulating performance (no anodizing required), fully electrolyte-resistant without swelling, and scratch-proof to protect battery films.
  • Flexible Customization: Fixture size, four-layer spacing, pressure level, and material selection (PP, 7075-T6/6061-T6 aluminum, 304/316 SS, PEEK, carbon steel, acrylic) can all be tailored to specific test requirements.

4. Important Notes
  1. Size Rule: Cell length & width = Fixture length & width − 30 mm; Four-layer spacing can be adjusted according to cell thickness, providing safe clamping space, and more uniform pressure distribution is achieved through the single nut design to ensure stable battery cycle test data.
  2. The PP four-layer fixture is upgraded from the three-layer fixture, with an additional layer added to the original three-layer structure; the pressure sensor is still an essential structural component, and the sensor data cable can be connected to external acquisition equipment to realize real-time monitoring of test pressure. The core improvement is the adoption of a single nut locking design, which makes the pressure distribution more uniform compared with the three-layer version. It is ultra-lightweight, easy to operate, has inherent insulating performance (no need for anodizing), excellent rigidity, outstanding load-bearing performance (max 500 kg), fully electrolyte-resistant (no swelling), scratch-proof to protect battery film, and does not interfere with test data.
  3. Fixture size, four-layer spacing, material and pressure level can be customized according to different battery cycle test requirements; PP is recommended for cost-sensitive, electrolyte-resistant testing scenarios, while 7075-T6 aluminum alloy is suitable for high-precision, high-strength testing scenarios; the four-layer structure supports testing thicker batteries.

This fixture accommodates pouch cells with thickness 0.1–2.5 cm and applies a standard working pressure of 350 kg via a single nut locking mechanism. The four-layer PP structure supports synchronous clamping and real-time pressure monitoring through an integrated sensor.

  • Battery thickness constraint: Compatible battery thickness ranges from 0.1 to 2.5 cm.
  • Working pressure constraint: Standard working pressure is 350 kg, customizable up to 500 kg within the fixture's load-bearing capacity.
  • Cell size constraint: Maximum cell length and width equal fixture dimensions minus 30 mm.
  • Clamping method description: Single nut locking combined with die spring buffer ensures uniform pressure distribution.
  • Material and customization constraint: Fixture is made of PP (polypropylene) and supports custom sizing, spacing, pressure, and surface treatment.

What are the trade-offs of using a polypropylene (PP) fixture compared to an aluminum fixture for pouch cell cycle testing under high clamping pressure?

PP is inherently insulating and lightweight, eliminating the need for anodizing and reducing fixture mass, but its load-bearing capacity is lower than aluminum's. The standard working pressure is 350 kg, customizable to 500 kg for the PP four-layer reinforced structure; at higher pressures, PP may have less rigidity than aluminum, though the single nut design distributes pressure uniformly to mitigate deformation.

How does the four-layer clamping structure accommodate pouch cells of varying thicknesses and sizes, and what are the dimensional constraints for custom cell sizes?

The four-layer spacing is adjustable based on cell thickness, supporting batteries from 0.1 to 2.5 cm. The maximum cell length and width are defined as fixture length/width minus 30 mm, as per the product specification table. For example, a 10x78x105 mm fixture accommodates cells ≤12x48x75 mm, and the largest 12x120x160 mm size accepts cells ≤28x90x130 mm.

What specific handling precautions should be taken when using the single nut locking mechanism with the die spring buffer to avoid damaging the pouch cell during clamping?

The single nut locking mechanism applies force uniformly through the die spring buffer, which acts as a cushion to prevent sudden impact. The scratch-proof design protects battery cells. Proper procedure requires tightening the nut gradually to allow the spring to compress evenly, ensuring pressure distribution remains uniform across the four layers. The standard working pressure is 350 kg, and the fixture's PP material is inherently insulating, so no additional grounding precautions are needed.

This PP four-layer fixture integrates a pressure sensor and single-nut locking for uniform clamping of pouch cells up to 2.5 cm thick, supporting working pressures up to 500 kg. Its lightweight design offers customization options but requires cells to be at least 30 mm smaller than fixture dimensions.

Positive

  • Integrated pressure sensor: The pressure sensor is an essential structural component enabling real-time pressure monitoring during cycling tests, providing direct feedback on cell swelling or clamping force variation.
  • Uniform pressure distribution: Single-nut locking combined with a die spring buffer and four-layer synchronous clamping ensures uniform pressure across the cell surface, reducing localized stress and protecting battery cells from damage.

Trade-offs

  • Limited maximum working pressure: Standard working pressure is 350 kg and can be customized up to 500 kg, but the PP four-layer structure's load-bearing capacity sets an upper limit that may not suffice for applications requiring very high compressive forces.
  • Cell size must be 30 mm smaller: To fit properly, the maximum cell length and width must be at least 30 mm less than the corresponding fixture dimensions, restricting the usable cell sizes for a given fixture size.
