Quick Assembly 3-Electrode Split Coin Cell (19mm ID) for Battery Material Testing - EQ-HSTC-III

EQ-HSTC-III splitable 3-Electrode test cell designed for high-throughput R&D battery material testing without any crimper. The smart design allows you to quickly and easily assemble and disassemble electrodes into the cell for test. This cell is especially suitable for post-analysis of target electrode to determine the limiting factors of battery efficiency and stability.  It can be used for both liquid-based and solid-state batteries. Two sides of the test cell connect to both electrodes (the anode and cathode), with the middle being connected to the reference electrode which can be used for monitoring voltage variations of the two electrodes.

 SPECIFICATIONS

Structure & Features  Pic. 1  Pic. 2	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 with Max. 100 °C working temperature  The air-tight design ensures zero electrolyte leakage Easy to separate and clean after use Spacer inside the test cell to press down on the electrode and prevent the electrode from curling Extending rod is included for each electrode O-ring is made of fluorine rubber to ensure no liquid electrolyte leaking Disc shape reference Li foil, which is easy to make by T-10 cutter Please click Pic. 1-2 left to see the assembling sketch To cut a cathode ring, you may order a ring cutter ( MSK-T-13A)
Optional Gold Plated Cell	The test cell can be gold-plated for extra corrosion resistance. Please choose 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: 19mm Diameter Max
Insertion Thickness	max. The thickness of the material that can be inserted is up to 6mm
Working Temperature	Max. 100 ºC  (Nylon material)
Spring	The test piece is compressed and held in place by one compression spring. Material: SS 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.
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 testing. Please email us about the availability of such a station.
