[EQ] Isostatic Pouch Cell Testing Vessel

The isostatic pouch cell testing vessel provides uniform and precisely controlled cycling pressure for all-solid-state battery pouch cells. The design employs compressed air as the pressurizing medium to achieve true isostatic loading up to 5 MPa. This enables accurate, reproducible electrochemical testing without mechanical stress gradients or torque-based adjustment.

Key Features

• Uniform pressure distribution (up to 5 MPa) using compressed air.
• Leak-tight steel vessel with replaceable O-rings.
• Two electrical feedthroughs for cycling connections.
• Compact, reusable, and easy to integrate with existing test setups.
• Ideal for studying pressure effects on solid-state battery interfaces.

Applications

• All-solid-state battery (ASSB) pouch-cell cycling.
• Interface and impedance studies under controlled pressure.
• Pressure-dependent performance evaluation and durability testing.

Specification

• Vessel dimensions: 3” (d) x 8” (l)
• Number of channels: 2ea
• Connection to cell: alligator clips
• Connection to cycler: male banana plugs (4mm)
• Pressure range: up to 5MPa
  • Warning: Operating above 5MPa may lead to leakage and/or explosion of the vessel.
• Compressed-air port: 8mm quick disconnect
• Temperature range: 10-30°C
• Optional compact air-compressor: 6"x10"x9" (portable)
