High-pressure, heat-resistant split cells for solid-state lithium battery electrolyte testing
Cell Lab PEEK Split Cell Test Kits are designed for the development and evaluation of solid-state electrolyte materials in lithium battery research. Made from high-performance polyether ether ketone (PEEK) with stainless steel working electrodes, these kits allow precise testing of ionic conductivity, electrochemical stability, and lithium symmetric cell performance.
The design supports up to 350 MPa pressure and 250 °C operating temperature, ensuring reliable conditions for laboratory and R&D studies. Available in 8 mm to 40 mm inner diameters, these split cells are compatible with liner sweep voltammetry (LSV) and lithium symmetric cell testing, making them an essential tool for both academic and industrial solid-state battery research.
High-performance PEEK construction — Excellent chemical resistance and thermal stability up to 250 °C.
High pressure capacity — Withstands up to 350 MPa for reliable electrolyte and electrode testing.
Versatile testing applications — Suitable for ionic conductivity, LSV, and lithium symmetric cell experiments.
Stainless steel working electrodes — Durable 3Cr13 or equivalent stainless steel ensures stability under load.
Customisable design — Additional sleeves, screws, and integration with pressure jig & load sensor available on request.
| Product No. | Inner Diameter (mm) | Outer Diameter (mm) | Sleeve Length (mm) | Assembled Height (mm) | Max Pressure (MPa) | Max Temperature (°C) | Sleeve Material | Electrode Material |
|---|---|---|---|---|---|---|---|---|
| CL0605 | 10 | 50 | 35 | 100 | 350 | 250 | PEEK | Stainless Steel |
| CL0606 | 12 | 50 | 35 | 86 | 350 | 250 | PEEK | 3Cr13 Stainless Steel |
Solid-state lithium battery R&D — Development of new solid electrolytes.
Electrochemical testing — Ionic conductivity, liner sweep voltammetry (LSV), and symmetric cell evaluation.
Quality control — Reliable performance testing for electrolyte and separator materials.
Academic research — For fundamental studies in solid-state ionics and electrochemistry.
Industrial battery labs — Applied in product development and pilot-scale testing.
Q1: What is the difference between the 10 mm and 12 mm kits?
The main difference is the inner cavity diameter and electrode height. Both models have the same maximum pressure and temperature ratings.
Q2: Can these kits be used for lithium symmetric cell testing?
Yes. Both kits are designed for lithium / lithium symmetric cell evaluation under controlled pressure and temperature.
Q3: Are additional parts available?
Yes. Pressure jig, load sensor, extra PEEK sleeves, and screws can be ordered separately.
Q4: What is the maximum working pressure?
Up to 350 MPa, suitable for solid electrolyte compaction and conductivity measurement.
Q5: Is customisation possible?
Yes. Cell Lab offers custom PEEK split cells upon request for specific research requirements.
