Solid-State Battery Test Mold with Locking Ring | Compact

This is a solid-state battery test mold optimized for high-frequency sample changes. Building on the proven compact PEEK-core design, this version adds an **upper locking ring** that enables fast, even pressure release after testing — making disassembly far more controllable and significantly reducing the risk of damage to the PEEK core, plungers, and samples during repeated handling. The PEEK inner core delivers excellent electrical insulation, chemical resistance, and mechanical stability up to 200 °C, while die-steel plungers, locking ring, liner, and sealing ring maintain reliable operation at 4 T of stack pressure. **The standard configuration supports up to 500 MPa**; a 1000 MPa version is available as a custom option on request. With an overall footprint of φ70 mm × H93 mm and a φ10 mm working cavity (customizable from 5–20 mm), the split-cell design enables quick assembly, disassembly, and electrode replacement — ideal for routine operation inside a glovebox.
