Solid-State Battery Assembly Mold for Laboratory Research – GT01

Name: GT01 Solid-State Battery Assembly Mold (Pressure Jig and Testing Cell Kit)

Mold Type: Pressure Jig + Integrated Test Cell

Product Code: XN-GT01

Description:

The GT01 is a versatile solid-state battery assembly mold combining pellet pressing, cell assembly, and electrochemical testing in a single unified jig. As a result, researchers can compact solid electrolyte pellets, layer cathode and anode components, and apply controlled stack pressure during electrochemical measurements — all without transferring the cell stack between separate fixtures, which is a leading source of interface degradation in solid-state battery research. The GT01 is rated to 500 MPa maximum working pressure, with a compact form factor (50 mm sleeve diameter, 65 mm assembly height) that fits comfortably inside standard glovebox workstations. Furthermore, the mold accommodates interior diameters from 6 mm to 20 mm, making it suitable for a wide range of pellet sizes used in academic and industrial solid-state battery laboratories. Free frame customization is available on request — including raised-frame variants for taller stack assemblies.

Application:

The GT01 mold is designed for laboratory-scale solid-state battery research, including solid electrolyte pellet pressing and densification, full-cell assembly with controlled stack pressure for cathode/electrolyte/anode interface optimization, in-situ electrochemical testing under sustained pressure (impedance spectroscopy, cyclic voltammetry, galvanostatic cycling), lithium-metal solid-state battery research where uniform stack pressure is critical for suppressing dendrite growth, and academic studies of solid-electrolyte/electrode interfacial resistance under variable pressure conditions.

Characteristics:

Strong compressive strength (≤ 500 MPa)

The GT01 is rated to 500 MPa maximum working pressure — sufficient for densifying sulfide-based solid electrolytes, oxide-based pellets, and composite cathodes that require high compaction to achieve target ionic conductivity. As a result, this mold supports the full range of common solid-state battery materials, from sulfide systems requiring 300–500 MPa to oxide systems near the upper end of its rated capacity.

Excellent insulating property via PEEK sleeve

The polyether ether ketone (PEEK) insulating sleeve provides high dielectric strength to ensure complete electrical isolation between the working and counter electrodes — a critical requirement for accurate electrochemical impedance measurements. Furthermore, PEEK delivers excellent chemical stability against lithium-metal anodes, sulfide electrolytes, and corrosive aprotic solvents commonly encountered in solid-state battery research.

Long-term mechanical stability

The combination of stainless steel frame and No. 4 mold-steel pushing rod delivers excellent dimensional stability under repeated pressure cycling, low surface friction during sample loading, and resistance to corrosion from electrolyte and reactive electrode materials. Therefore, this mold is well-suited for high-throughput laboratory environments where reliability and ease of cleaning are critical.

Compact form factor for glovebox use

With a 50 mm sleeve diameter and 65 mm assembly height, the GT01 features a streamlined design optimized for use inside argon-filled gloveboxes. As a result, researchers can assemble lithium-metal solid-state cells and handle moisture-sensitive sulfide electrolytes (Li₆PS₅Cl, Li₂S–P₂S₅, etc.) without exposure to ambient air or moisture — preserving sample integrity for accurate research data.

Free frame customization on request

The GT01 supports free frame customization — including raised-frame variants for taller stack assemblies, modified outer dimensions, and specialized component arrangements. Therefore, researchers with non-standard cell geometries or specialized experimental setups can obtain a tailored configuration without additional engineering charges.

Multiple interior diameters cover common pellet sizes

Standard interior diameters cover 6 mm, 10 mm, 12 mm, 15 mm, and 20 mm to match different pellet sizes and active-area requirements across academic and industrial solid-state battery research workflows.

Recommended Operating Procedure:

1. Clean all mold components with isopropyl alcohol and dry thoroughly before each use. 2. Apply a thin layer of vacuum grease or anti-seize compound between the pushing rod and the PEEK sleeve to reduce friction. 3. Inside an argon-filled glovebox, load the bottom electrode current collector, then sequentially add cathode powder, solid electrolyte powder/pellet, and anode (lithium foil or anode powder). 4. Insert the top pushing rod and apply the target pressure using a hydraulic press (do not exceed 500 MPa). 5. Tighten the locking screws on the frame to maintain stack pressure during transfer out of the glovebox. 6. Perform electrochemical measurements at the required temperature. 7. After testing, release pressure gradually, disassemble in the glovebox, and clean all components with alcohol before storage.

Packaging & Storage:

Each GT01 mold ships fully assembled in a protective foam-lined case with all components, including the stainless steel frame, PEEK sleeve, No. 4 mold-steel pushing rods, sealing O-rings, and locking knobs. Therefore, store in a dry environment (15–25 °C, RH < 40 %) protected from dust and moisture. After each use, clean components with isopropyl alcohol, apply a thin layer of vacuum grease to metal surfaces, and store in the original case to prevent oxidation and corrosion.

Safety:

For research and industrial laboratory use only. Do not exceed the maximum working pressure (500 MPa) — exceeding this limit may result in mold damage, sample loss, or personal injury. Always wear appropriate PPE (safety glasses, gloves) when applying pressure. When working with lithium-metal anodes, sulfide electrolytes, or other reactive materials, perform all assembly and disassembly inside an argon-filled glovebox. Refer to the included user manual for complete safety and operating instructions.

Note: Specifications listed above are typical and for reference only. Actual performance and pressure requirements depend on solid electrolyte chemistry, pellet thickness, and target densification level — consult published literature for guidance on optimal pressure conditions for specific solid-state battery systems.
