4. Important Notes

 

Size Rule: Cell length & width = Fixture length & width − 30 mm; Three-layer spacing can be adjusted according to cell thickness, providing safe clamping space and uniform pressure to ensure stable battery cycle test data.

 

The PP three-layer fixture is upgraded from the two-layer fixture. The core upgrade is the addition of a pressure sensing layer, where the pressure sensor is an essential structural component. The sensor data cable can be connected to external acquisition equipment to realize real-time monitoring of test pressure. Compared with stainless steel and aluminum alloy versions, it is more ultra-lightweight, fully electrolyte-resistant (no swelling), and scratch-proof, suitable for low-pressure cycle testing, no interference with test data.

 

Fixtue size, three-layer spacing, material and pressure level can be customized according to different battery cycle test requirements; food-grade PP is recommended for high-safety testing scenarios, while industrial-grade PP is suitable for general industrial low-pressure scenarios; the maximum load should not exceed 300kg to avoid structural damage.
