4. Important Notes

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.

 

The stainless steel 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 has excellent corrosion resistance and wear resistance, strong load-bearing performance (max 600kg), stable structure, easy to clean and maintain, and does not interfere with test data.

 

Fixture size, four-layer spacing, material and pressure level can be customized according to different battery cycle test requirements; 316 stainless steel is recommended for harsh environments such as leakage/immersion testing, while 304 stainless steel is suitable for general industrial testing scenarios; the four-layer structure supports testing thicker batteries or multiple batteries simultaneously.
