This fixture requires operation within a dry room environment to prevent signal contamination and corrosion. All digital connection channels must be properly insulated to avoid pressure sensor data interference during long-term thermal validation loops.
- Environmental Requirement: Operate the fixture exclusively in a dry room atmosphere to maintain sensor accuracy and prevent electrolyte-related degradation.
- Electrical Insulation: Ensure all pressure sensor data cables are electrically insulated from external noise sources to preserve signal integrity.
- Surface Protection: The anodized aluminum surface prevents scratching of delicate pouch cell film; inspect for damage before each use.
- Pressure Monitoring: Continuously monitor the integrated pressure sensor during cycling to detect any deviation from uniform force distribution.
- Material Compatibility: The 5052 aluminum alloy provides corrosion resistance against common organic electrolytes; avoid prolonged exposure to incompatible solvents.
This procedure describes the safe initialization and deployment of the four-layer pouch cell test fixture for cycle validation. Follow these steps to ensure uniform pressure distribution and accurate data acquisition.
Required Equipment: Single nut locking mechanism, Pressure sensor with data cable, Anodized aluminum plates
- Inspect Fixture
Inspect the fixture plates for cleanliness and anodized surface integrity before each use. - Position Cell
Place the pouch cell centrally within the four-layer plate stack ensuring proper alignment. - Apply Clamping Pressure
Tighten the single nut gradually to apply the desired clamping pressure within the rated capacity. - Connect Sensor Cable
Connect the pressure sensor data cable to the monitoring system and verify insulation. - Verify Alignment
Confirm uniform pressure distribution by checking parallel alignment of all plates. - Transfer to Dry Room
Transfer the assembled fixture into a dry room environment for testing. - Monitor During Cycling
Monitor pressure sensor readings continuously throughout the battery cycling process.
What is the maximum working pressure of the 5052 aluminum alloy version, and how does it compare to the optional 7075-T6 alloy for high-pressure pouch cell cycling?
The standard 5052 aluminum alloy fixture supports a working pressure of 300 kg, customisable up to 400 kg. For higher pressure demands, the optional 7075-T6 alloy (not included in this SKU) offers a standard 350 kg and maximum 500 kg, providing superior rigidity for precision single-cell lifecycle evaluations. The trade-off is that 7075-T6 is heavier and more expensive than 5052, which is already lightweight and corrosion-resistant.
What is the maximum pouch cell size that can be accommodated in the 120×160 mm variant, and does the fixture include an integrated pressure sensor for real-time monitoring?
For the 120×160 mm size (10 mm plate thickness), the maximum compatible cell length and width is 90×130 mm, calculated by subtracting 30 mm from fixture dimensions. The fixture includes a built-in pressure sensor component with a real-time acquisition cable, allowing direct external pressure data tracking without electrical noise interference during cycling.
What environmental conditions and handling precautions are required to prevent pressure sensor interference when using the ATM-PCBT-AL5052-4L?
The fixture must be operated in a dry room testing environment to avoid external signal contamination. All digital connection channels must be properly insulated, and the anodized surface layer provides scratch-proof protection for delicate battery film. The pressure sensor data lines should be carefully monitored to prevent interference before long-term thermal validation loops.
The ATM-PCBT-AL5052-4L is a 4-layer pouch cell test fixture precision-machined from 5052 aluminum alloy, featuring a single-nut clamping mechanism for uniform pressure distribution. It accommodates cell sizes up to 150×180 mm with thickness from 0.1 mm to 2.5 cm and a standard working pressure of 300 kg, customizable to 400 kg, making it suitable for cost-sensitive, corrosion-resistant single-cell cycle validation.
Positive
- Uniform single-nut pressure distribution: The centralized single-nut locking layout delivers balanced parallel load transfer across the cell surface, minimizing stress localization and ensuring reproducible baseline data.
- Corrosion-resistant 5052 alloy with anodized insulation: Premium 5052 aluminum alloy with anodized surface treatment provides outstanding electrolyte splash resistance and scratch-proof protection for delicate pouch cell films.
Trade-offs
- Standard pressure limit of 300 kg: The default working pressure is 300 kg (upgradable to 400 kg upon customization), which may constrain applications requiring higher mechanical loads for specific cell chemistries or aging protocols.
- Sensitive to environmental signal interference: The integrated pressure sensor data lines require careful insulation and must be operated within dry room conditions to avoid external signal contamination during long-term thermal validation loops.
