Quick Assembly Split Coin Cell ( 20mm ID) for Battery Material testing, No More Crimper - EQ-HSTC

In stock
Item Number: HSTC20


EQ-HSTC split-able test cell is designed for high-throughput R&D battery material testings without any crimper. The smart design allows you to quickly and easily assemble a coin cell by hand tightening to increase research efficiency. It can be used for both liquid and solid-state batteries.


Structure & Features

  • Easy cell assembling by "thread-in" the bottom contacting plate and top plunger into the Nylon body.
  • Stainless Steel contact plate and plunger.
  • The Body is made of Nylon body with Max. 100oC working temperature 
  • ( PTFE is optional with 200oC Max. working temperature )
  • The air-tight design ensures zero electrolyte leakage
  • Easy to separate and clean after use
  • Same functionality as "Swagelok Type Cell" but with more size options for electrode and separator.
  • Spacer inside the test cell to press down on the electrode and prevent the electrode from curling
  • Directly clamp on MTI battery analyzer without wire connection for quick testing
  • Extending rod included for each electrode
  • O-ring is made of Fluorine rubber to ensure no liquid electrolyte leaking
Optional Gold Plated Cell

  • The test cell can be gold plated for extra corrosion resistance, please chose from the personalization section.
  • Please click here to order your own gold plating kit.
  • Note: Customized (Au coated) test cells are non-returnable and non-exchangeable.
Electrode Insert Dia.
  • Standard diameter that can be put inside:  20mm Diameter Max
Insertion Thickness
  • max. the thickness of the material that can be inserted is up to 6mm
Working Temperature
  • Max. 100 ºC  (Nylonmaterial)
  • Test piece is compressed and held in place by one compression spring.
  • Material: SUS 304
  • Spring Rate / Stiffness: 7.9 N/mm (806 g/mm)
  • Dimensions when free: 5 mm OD × 3.4 mm ID
  • Length under maximum compression: 7.2 mm
  • Please contact MTI to order replacement springs.
Gold Coating (Optional)
  • Anti-corrosive Au coating on the base contact plunger and inserts is available upon request
  • Note: Customized (Au coated) test cells are non-returnable and non-exchangeable.
Testing Station (Optional)
  • To perform a parallel test for multiple cells, simply arrange them in a dock station and have it connected to MTI multi-channel battery analyzer for cycle life, coulombic efficiency...testings. Please email us for the availability of such a station.
