Solid-State Battery Assembly Mold for Laboratory Research – GT02

Name: Solid-State Battery Assembly Mold for Laboratory Research – GT02

Mold Type: Standard Pressure Jig + Integrated Test Cell

Product Code: XN-BM-GT02

Description:

The GT02 is the standard-version solid-state battery assembly mold in Xnergy’s GT-series, 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 GT02 is rated to ≤ 500 MPa maximum working pressure and 200 °C maximum operating temperature, supporting both ambient and elevated-temperature solid-state battery studies. Furthermore, the mold features a slim, tall form factor (40 mm sleeve diameter, 100 mm assembly height) that supports taller cell stacks while accommodating 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 GT02 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), elevated-temperature solid-state battery characterization up to 200 °C, 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:

Withstands high temperature up to 200 °C

The GT02’s 200 °C maximum operating temperature accommodates elevated-temperature solid-state battery testing, including sulfide electrolyte densification studies, polymer electrolyte glass-transition characterization, and high-temperature cycling validation. As a result, this mold supports both room-temperature ionic-conductor research and moderately elevated-temperature solid-state battery development without requiring specialized high-temperature fixtures.

Stable chemical properties for reactive solid-state systems

The GT02’s combination of stainless steel frame, PEEK insulating sleeve, and No. 4 mold-steel pushing rod delivers stable chemical properties against lithium-metal anodes, sulfide solid electrolytes (Li₆PS₅Cl, Li₂S–P₂S₅), and corrosive aprotic solvents commonly encountered in solid-state battery research. Therefore, this mold prevents contamination of test samples and supports long-duration experiments without component degradation.

Strong compressive strength (≤ 500 MPa)

The GT02 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. Consequently, 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 and mechanical resilience under repeated pressure cycling.

Tall, slim form factor for stacked-cell assemblies

With a 40 mm sleeve diameter and 100 mm assembly height, the GT02 features a taller form factor than the GT01 series — providing additional vertical clearance for thicker cell stacks, multi-layer electrode assemblies, and configurations requiring more compression travel. As a result, the GT02 is well-suited for full-cell solid-state battery research where electrode stack thickness exceeds standard pellet dimensions.

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, the GT02 is well-suited for high-throughput laboratory environments where reliability and ease of cleaning are critical.

Free frame customization on request

The GT02 supports free frame customization — including raised-frame variants for even 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.

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 (do not exceed 200 °C). 7. After testing, release pressure gradually, disassemble in the glovebox, and clean all components with alcohol before storage.

Packaging & Storage:

Each GT02 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) or maximum operating temperature (200 °C) — exceeding these limits may result in mold damage, sample loss, or personal injury. Always wear appropriate PPE (safety glasses, gloves) when applying pressure or operating at elevated temperature. 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 and temperature conditions for specific solid-state battery systems.
