GT02 TQ Ventilated Solid-State Battery Assembly Mold – φ10–20mm, 800 MPa, Ventilation Version

Name: GT02 TQ Ventilated Solid-State Battery Mold (Ventilation Version of GT02 Series)

Mold Type: High-Pressure Solid-State Pressure Jig with Integrated Ventilation

Product Code: XN-BM-VSSBM (alternative reference: GT02 TQ / EX02 TQ)

Description:

The GT02 TQ is the ventilation version of Xnergy’s GT02 solid-state battery assembly mold series — engineered for high-pressure solid-state battery research that requires controlled gas-release capability during cycling. As a result, this mold supports research scenarios where outgassing, decomposition gases, or thermal-runaway gas products (CO₂, H₂S, O₂) must be safely vented away from the cell stack — critical for sulfide solid electrolytes (which can release H₂S on moisture exposure), high-voltage NCM cathodes (which generate CO₂ on decomposition), and high-energy cell research where thermal runaway is a possibility. The GT02 TQ is rated to ≤ 800 MPa maximum working pressure, accommodates an inner diameter range of φ10–20 mm (the ceramic-chamber version is fixed at φ10 mm), and features a compact 80 × 100 mm form factor. Furthermore, the mold maintains outstanding electrical insulation properties even under high temperature, high pressure, and humid conditions — with a dielectric constant of 3.2 and dielectric loss of just 0.02 at 10 Hz across a wide frequency range. Customization is available on request, and the frame can be raised free of charge.

Application:

The GT02 TQ ventilated mold is designed for advanced solid-state battery R&D experiments where gas evolution, thermal stability, or moisture-control are critical, including high-voltage NCM cathode research where CO₂ outgassing is expected during charge-discharge cycling, sulfide solid electrolyte (Li₆PS₅Cl, Li₂S–P₂S₅) research where H₂S release must be safely vented, thermal runaway studies and accelerated aging tests under controlled venting conditions, fabrication-technology development for solid-state battery production lines (NCM crystal, sulfide compaction, cathode fabrication), high-pressure solid-state battery research at humid conditions where insulation reliability is essential, energy density evaluation studies of advanced solid-state cell architectures, and academic studies of inherent stability mechanisms in solid-state battery systems exposed to controlled gas atmospheres.

Characteristics:

Integrated ventilation for safe gas-release research

The GT02 TQ’s defining feature is its integrated ventilation design — providing controlled release of gases generated during solid-state battery cycling (CO₂ from high-voltage cathode decomposition, H₂S from sulfide-electrolyte moisture exposure, O₂ from cathode oxygen-release). As a result, researchers can safely conduct cycling experiments that would be hazardous in fully sealed molds, while still maintaining the mechanical pressure and thermal control required for solid-state battery research.

Outstanding electrical insulation under high-T, high-P, humid conditions

The PEEK insulating sleeve maintains exceptional electrical insulation performance even under simultaneous high-temperature, high-pressure, and humid conditions — a unique combination of stresses encountered in solid-state battery research. Therefore, the GT02 TQ delivers reliable EIS data without leakage current artifacts that compromise impedance measurements in less-capable mold designs.

Low dielectric constant and dielectric loss across wide frequency range

The PEEK insulating system delivers a dielectric constant of just 3.2 and dielectric loss of 0.02 at 10 Hz at room temperature, with stable performance across the full frequency range used in EIS measurements. Consequently, the GT02 TQ contributes minimal capacitive coupling and dielectric absorption to the cell impedance, allowing researchers to isolate the intrinsic ionic conductivity of the solid electrolyte more accurately.

High maximum working pressure (≤ 800 MPa)

The GT02 TQ is rated to 800 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. Furthermore, this pressure rating substantially exceeds the standard GT02 mold (500 MPa), making the GT02 TQ suitable for the most demanding solid-state battery research applications.

Wide inner diameter range (φ10–20 mm)

The GT02 TQ supports an inner diameter range of φ10–20 mm — covering the full spectrum of solid electrolyte pellet sizes used in academic and industrial laboratories. As a result, researchers can match the pellet diameter to their specific experimental requirement (small samples for material screening, larger samples for area-averaged EIS studies). Note that the ceramic inner chamber version is fixed at φ10 mm.

Compatible with NCM, sulfide, and oxide chemistries

The GT02 TQ is compatible with the full range of solid-state battery chemistries — including high-voltage NCM cathodes (where CO₂ outgassing benefits from venting), sulfide solid electrolytes (Li₆PS₅Cl, LGPS — where H₂S venting is essential for safety), and oxide solid electrolytes (LLZO, LATP). Therefore, this mold serves as a versatile platform for the most active areas of solid-state battery research.

Optional ceramic inner chamber for highest chemical inertness

The Venting Version with Ceramic Inner Chamber configuration provides ceramic chemical inertness against the most reactive solid-state battery materials — including lithium metal anodes, sulfide solid electrolytes, and oxidizing cathode surfaces. As a result, this premium version eliminates contamination risks that can compromise long-duration EIS and cycling research.

Optional gold-plated electrodes for ultra-low contact resistance

The Gold-Plated Electrodes (Cathode + Anode) configuration delivers the lowest contact resistance available, supporting the highest-quality EIS data and providing the best electrochemical interface for high-voltage NCM and lithium-metal solid-state cells. Therefore, this premium configuration is the preferred choice for advanced research labs where minor contact-resistance variations would mask the underlying electrochemistry.

Free frame customization on request

The GT02 TQ 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.

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 insulating 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 800 MPa). 5. Connect the venting port to an appropriate exhaust line or controlled-atmosphere system if gas-release studies are planned. 6. Tighten the locking screws on the frame to maintain stack pressure during transfer out of the glovebox. 7. Perform electrochemical measurements at the required temperature and pressure conditions. 8. After testing, ensure the venting line is clear of pressurized gas, release pressure gradually, disassemble in the glovebox, and clean all components with alcohol before storage.

Packaging & Storage:

Each GT02 TQ mold ships fully assembled in a protective foam-lined case with all components, including the stainless steel frame, PEEK insulating sleeve, special-steel pushing rods, venting hardware, sealing components, and assembly hardware. 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, inspect the venting hardware for blockages, and store in the original case to prevent oxidation, corrosion, and seal damage.

Safety:

For research and industrial laboratory use only. Do not exceed the maximum working pressure (800 MPa) — exceeding this limit may result in mold damage, sample loss, or personal injury. Always wear appropriate PPE (safety glasses, gloves) when applying pressure or handling reactive materials. For sulfide-electrolyte research where H₂S evolution is possible, connect the venting port to a fume hood, exhaust line, or scrubber system — H₂S is a toxic gas at low concentrations. For high-voltage NCM cathode research where CO₂ outgassing is expected, ensure adequate ventilation. 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, target densification level, and gas-evolution characteristics — consult published literature for guidance on optimal pressure conditions and venting protocols for specific solid-state battery systems.
