Product Options

Sleeve Inner Size:


EQ-PSC is a split-able and air-tight coin cell set with a sleeve made out of Nylon, PEEK or Si3N4. The split cell can be placed in a lab press and applied pressure up to 20 MPa, which is designed for researching the effect of pressure on solid-state battery performance. It can also be used for easy coin cell assembling without any screw and crimping tool. It can be customized into various sizes (8, 10, 12, 15, 20, and 25 mm diameter) to accept all sizes of electrodes and separators. (Please choose the size and material from Product Options
Note: Customized (Au-coated) test cells are non-returnable and non-exchangeable.
MTI has granted the patent 2016205216100 for the Pressure Controlled (up to 20 MPa) Split Coin Cell - EQ-PSC since June 2016.


Structure & Material

  • Pushing rods (top and bottom) are made of stainless steel. (Gold plating is available upon request at an extra cost)
  • Sleeve Material: Nylon or PEEK or Si2N4 is selectable at the product option.
  • Poly Ether Ether Ketone (PEEK) is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. (Click here to see properties)
 Instruction on How to Use 
  • Simply put the electrode, separator, and electrolyte materials into the die with no screws required
  • Place the die into a compact lab press to apply pressure without crimping (click pics 1-2 to order lab press)
  • Connect the current leads from pushing rods to a battery analyzer for testing
  • You may use a thickness fixture (Pic 3 ) to measure the expansion of assembled battery during charging & discharging
  • You may use a digital press to apply pressure ( Pic. 4)

  • If you need a higher working temperature and higher pressure,  please choose Si3N4 ceramic die as Pic. 1
  • If you need anti0corrosion, please consider coating at extra cost  (Pic. 2)
  • If you would like a test cell for testing a solid-state cell > 150oC,  please order s Test cell made of Si3N4 ceramic as an option, which can be heated up to 500oC. Please click the Pic. 3& 4 to see the detail :
