Ceramic Solid-State Battery Assembly Mold for Laboratory Research – GT02-TC

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

Mold Type: Standard Ceramic-Type Pressure Jig + Integrated Test Cell

Product Code: XN-BM-GT02TC

Description:

The GT02-TC is the standard ceramic-version of Xnergy’s GT02 solid-state battery assembly mold 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 defining feature of the GT02-TC is its ceramic-based insulating construction, providing excellent chemical inertness against lithium-metal anodes, sulfide solid electrolytes, and reactive cathode materials, along with superior thermal stability over polymer-only insulating sleeves. Furthermore, the mold features a tall, slim form factor (40 mm sleeve diameter, 100 mm assembly height) that supports thicker cell stacks and multi-layer electrode assemblies. Free frame customization is available on request — including raised-frame variants for taller stack assemblies.

Application:

The GT02-TC mold is designed for laboratory-scale solid-state battery research where chemical inertness is critical, 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, sulfide-electrolyte studies that benefit from ceramic chemical inertness, and academic studies of solid-electrolyte/electrode interfacial resistance under variable pressure conditions.

Characteristics:

Ceramic insulating construction for chemical inertness

The GT02-TC’s ceramic-based insulating components deliver superior chemical inertness against reactive electrode materials, including lithium-metal anodes, sulfide solid electrolytes (Li₆PS₅Cl, Li₂S–P₂S₅), and oxidizing cathode surfaces. As a result, this mold prevents contamination of the test sample by polymer outgassing or dissolution — a critical requirement for accurate impedance spectroscopy and long-duration solid-state battery experiments.

Multi-material insulating system (ceramic + PEEK + PA)

Unlike single-material insulating sleeves, the GT02-TC integrates three engineered insulating materials — ceramic for primary chemical inertness, PEEK for mechanical resilience under pressure cycling, and PA polymer for sealing. Therefore, this layered insulating system delivers performance advantages that no single material can achieve alone — combining chemical stability, mechanical strength, and reliable sealing in one mold.

Strong compressive strength (≤ 500 MPa)

The GT02-TC 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.

Tall, slim form factor for stacked-cell assemblies

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

High mechanical stability under repeated pressure cycling

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

Compact form factor for glovebox use

Despite its tall profile, the 40 mm sleeve diameter keeps the GT02-TC compact enough for use inside argon-filled gloveboxes. As a result, researchers can assemble lithium-metal solid-state cells and handle moisture-sensitive sulfide electrolytes without exposure to ambient air or moisture — preserving sample integrity for accurate research data.

Free frame customization on request

The GT02-TC 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.

Helps your solid-state battery research achieve a qualitative leap

The high precision, tight dimensional tolerances, and chemically inert ceramic construction of the GT02-TC ensure exceptional mold stability across long-duration experiments. As a result, this mold can help your solid-state battery products achieve a qualitative leap in performance characterization — from interface resistance measurements to long-cycle stability validation.

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 ceramic 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 GT02-TC mold ships fully assembled in a protective foam-lined case with all components, including the stainless steel frame, ceramic insulating sleeve, PEEK and PA seals, 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 of metal components and to protect the ceramic insulator from impact damage.

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. Handle the ceramic sleeve with care — although chemically inert and mechanically stable, ceramic components can crack under impact loading or excessive thermal shock. 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.
