USE METHOD
Use Method
Optimized into a concise Before testing / During testing / After testing workflow for research operation and training.
Preparation Before Testing
Confirm electrolyte-material compatibility and check whether the conductive posts, sealing rings, reaction chamber, and nuts are clean, dry, and undamaged. Air-sensitive systems are recommended to be handled in a glovebox.
Assembly & Electrolyte Filling
Install components according to the structure diagram. The electrodes and separator should be centered and flat. Add a small amount of electrolyte during stacking to wet each layer and ensure that the separator fully covers the reaction area and effectively isolates the positive and negative electrodes.
Locking & Connection
Evenly tighten the nuts on both ends so the sealing rings fit properly and form leak-proof sealing. After installing the conductive terminal posts, connect to an electrochemical workstation, LAND, or NEWARE device and confirm polarity and channel settings.
Maintenance After Testing
After testing, slowly release pressure, disassemble all components, and clean them according to electrolyte type. Store only after full drying to prevent residual-liquid corrosion, cross-contamination, or reduced repeatability in the next test.
Before testing, it is recommended to use a multimeter to confirm that there is no short circuit. If leakage or abnormal impedance is found, recheck separator size, sealing-ring position, and uniform locking on both sides.
ASSEMBLY METHOD
Assembly Method
The following shows the general assembly process. Assembly is recommended from right to left.
Spring-Loaded Structure Assembly Process
1 Right-Side Base Part Pre-Assembly
Take the right-side PTFE nut first, insert the 316L conductive metal cylinder from the outside, then place the PTFE sealing ring on the inner end of the metal cylinder to complete right-side pre-assembly.
2 Install the Right-Side Assembly Into the Reaction Chamber
Hold the reaction chamber and push the right-side pre-assembled part inward from the threaded hole on the right end of the chamber, so the metal cylinder tip is only slightly exposed inside the chamber. Do not push it fully through.
3Install negative electrode / separator / positive electrode in Sequence
Add a small amount of electrolyte to wet each layer. Place the negative electrode first, then lay the separator flat, and finally place the positive electrode. The separator should be larger than the electrode pieces and fully cover the chamber cross-section to isolate the two electrodes and prevent short circuits.
4 Install Conductive Spacer and Spring
After the electrode stack is completed, first insert the 316L conductive spacer with raised boss, with the raised side contacting the positive electrode piece. Then install the matching spring to provide stable elastic compression.
5 Left-Side Sealing and Locking
Take another conductive metal cylinder, place the PTFE sealing ring on it, insert it from the left end of the reaction chamber, then cover it with the left PTFE nut. Evenly tighten both nuts to form leak-proof sealing.
6 Install Conductive Terminal Posts and Finish
Tighten the brass-colored copper conductive terminal posts onto the exposed conductive metal cylinder ends on both sides. After confirming the threads are tightened and the conductive path is complete, the fixture is ready for testing.
Dual-Post Structure Assembly Process
1 Right-Side Metal Cylinder Pre-Assembly
Take the right-side PTFE nut first, insert the 316L conductive metal cylinder through the nut, then place the PTFE sealing ring on the inner end of the metal cylinder to complete single-side pre-assembly.
2 Install the Right-Side Assembly Into the Reaction Chamber
Insert the right-side conductive metal cylinder through the threaded hole at the right end of the reaction chamber and push it in slowly until the metal cylinder tip is slightly exposed inside the chamber.
3 Layer the Electrode Stack and Wet Each Layer
Place the negative electrode, separator, and positive electrode in sequence, adding a small amount of electrolyte between layers for wetting. The separator should fully cover the reaction area and be larger than the positive and negative electrodes to prevent short circuits.
4 Left-Side Dual-Post Assembly
Take another conductive metal cylinder, insert it through the left-side nut, place the sealing ring, and install it inward from the left end of the reaction chamber. Align the chamber threads before tightening.
5 Evenly Tighten Both Ends
Tighten the left and right nuts evenly and synchronously so the sealing rings fit properly. The two metal cylinders directly clamp the internal cell stack and provide leak-proof chamber sealing.
6 Install Conductive Terminal Posts and Finish
Finally, tighten the brass-colored copper conductive terminal posts on both ends. After confirming the conductive path is complete and there is no looseness or leakage, electrochemical performance testing can begin.

FAQ
FAQ
Nine core questions are retained for quick selection and use.
01
What is the standard electrode size?
The standard size is Φ14 mm. Φ6–Φ20 mm, square openings, and other special sizes can be customized.
02
What is the difference between the spring-loaded structure and the dual-post structure?
The spring-loaded structure provides continuous axial pressure and is more suitable for tests requiring stable contact pressure. The dual-post structure directly clamps through the metal cylinders on both sides, making assembly simpler and pressure adjustment more intuitive.
03
How should the four reaction chamber materials be selected?
PP is suitable for general testing; PTFE is suitable for corrosive and broad-temperature systems; PEEK is suitable for high-temperature and high-strength requirements; PMMA is suitable for transparent-observation experiments not exceeding 60°C.
04
How should 316L, titanium, and molybdenum conductive posts be selected?
316L is suitable for most general systems; titanium is suitable for corrosion-resistant requirements; molybdenum is suitable for specific experimental systems that explicitly require molybdenum.
05
Can it be used for lithium, sodium, and potassium metal batteries?
Yes. electrode handling, assembly, electrolyte filling, and sealing are recommended to be completed in an inert-atmosphere glovebox.
06
Can it connect to LAND, Neware, or an electrochemical workstation?
Yes. It can connect to common testing platforms through alligator clip to O-terminal leads. Confirm channel polarity and range settings before use.
07
How should electrolyte leakage be handled?
Stop testing and release pressure. Check whether the sealing ring is misplaced, whether the separator interferes with the sealing area, whether the chamber and threads are clean, and whether both sides are tightened evenly.
08
Why is an insulating film needed when using a metal housing?
A metal housing may form an unintended conductive path. Mylar or another insulating film should be used to prevent external short circuits.
09
How should the fixture be cleaned and stored after testing?
Clean the conductive posts, chamber, and sealing components according to electrolyte safety requirements. Store separately after full drying to avoid residual-liquid corrosion and cross-contamination.
