This document outlines the operational constraints for the ATM-PCBT-AL7075 pouch cell battery test fixture. The fixture imposes specific sizing, pressure, and material compatibility requirements to ensure safe and accurate battery cycle testing.
- Cell Sizing Constraint: Cell length and width must be at least 30 mm less than fixture length and width to prevent clamping edge interference.
- Working Pressure Range: Standard working pressure is 250 kg and can be customized up to 350 kg for high-pressure testing without exceeding fixture limits.
- Cell Thickness Compatibility: The fixture accommodates cell thicknesses from 0.1 cm to 2 cm via the die spring buffer and screw locking mechanism.
- Material Selection Guidance: When electrolyte exposure is expected, 316 stainless steel or PEEK alternatives should be selected over 7075 aluminum to avoid corrosion.
- Plate Deformation Prevention: The aircraft-grade 7075-T6 aluminum alloy construction prevents plate deformation under maximum clamping load.
What is the maximum working pressure for the 8x78x105mm fixture size of the ATM-PCBT-AL7075?
The standard working pressure of the ATM-PCBT-AL7075 is 250 kg, customizable up to 350 kg, but the maximum load depends on fixture size. According to the fixture size table, the 8x78x105mm size has a maximum theoretical load of 250 kg, while larger sizes (120x160mm and above) support up to 350 kg. Customization beyond 250 kg is only possible for fixtures sized to handle the higher load.
How do I calculate the maximum cell dimensions for a given fixture size in the ATM-PCBT-AL7075?
The maximum cell length and width are equal to the fixture length and width minus 30 mm, providing safe clamping space for stable testing. For example, the 8x100x130mm fixture accommodates cells up to 10x70x100mm, as shown in the fixture size table. The compatible battery thickness range is 0.1–2 cm regardless of fixture size.
Is the 7075-T6 aluminum alloy fixture suitable for use with corrosive electrolytes?
The default 7075-T6 aluminum alloy is anodized for electrical insulation and scratch resistance, but it does not provide specific electrolyte corrosion resistance. For applications involving electrolyte exposure, Atomfair recommends optional materials such as 316 stainless steel or engineering plastics like PEEK, which offer superior corrosion resistance. The key notes direct users to contact technical support for details on preventing electrolyte corrosion.
The ATM-PCBT-AL7075 is a pouch cell test fixture constructed from aircraft-grade 7075-T6 aluminum alloy, providing high rigidity and anodized electrical insulation. It operates at 250-350kg clamping pressure with a 4-corner screw and die spring system, but requires cell dimensions to be at least 30mm smaller than fixture size and is not optimized for electrolyte corrosion resistance.
Positive
- Aircraft-grade 7075-T6 aluminum alloy: The 7075-T6 aluminum alloy delivers the highest mechanical strength among aluminum options, preventing plate deformation under maximum testing pressures of 350 kg.
- Anodized insulation and scratch resistance: Advanced anodizing treatment provides robust electrical insulation and premium surface scratch resistance during repeated laboratory assembly.
Trade-offs
- Mandatory 30mm cell-to-fixture margin: Cell length and width must be at least 30mm less than fixture dimensions, reducing usable clamping area and limiting maximum cell size per fixture.
- Limited electrolyte corrosion resistance: The 7075 aluminum alloy is not listed with enhanced electrolyte resistance; users testing cells with leakage risk should consider stainless steel alternatives for long-term durability.
