In-situ XRD Electrochemical Cell (Three-Electrode System), Model: EC-XRD1

EC-XRD1 In-situ XRD Electrochemical Cell A compact three-electrode cell for operando XRD monitoring of electrochemical phase and structural evolution. Product Overview The EC-XRD1 provides direct X-ray access to an interchangeable disk working electrode through an X-ray-transparent beryllium (Be) window while maintaining three-electrode electrochemical control. Its compact flow-compatible design supports both syringe filling and external electrolyte circulation, making it suitable for tracking phase transformations and structural evolution of electrode materials under applied electrochemical conditions. Technical Specifications WE-optical window distance < 3 mm Optical window diameter Ø25 mm (effective diameter Ø20 mm) Chamber structure Single-chamber Electrode system Three-electroder Working electrode Ø5 mm glassy carbon disk electrode (standard); Au, Pt, Ag, graphite, or pyrolytic graphite disk electrodes (optional) Reference electrode Ag/AgCl or Ag/Ag⁺ electrode Counter electrode Ø1 mm Platinum wire electrode Cell body material PEEK + Ti Optical window material Beryllium (Be) Cell body dimensions L65 × W65 × H19 mm Note: Solid beryllium is relatively stable and poses low skin-contact risk; avoid inhaling dust or aerosols and wash hands after handling. Key Features Direct Structural Observation Be-window access and a short X-ray path enable direct probing of the working-electrode surface Flexible Disk-Electrode Selection Uses a standard Ø5 mm glassy carbon disk and supports interchangeable Au, Pt, Ag, graphite, and pyrolytic graphite disks Operando Phase-Evolution Analysis Enables potential- and time-dependent monitoring of crystalline phase transformations and structural evolution of electrode materials Instrument Compatibility XRD System Compatibility Compatible with laboratory X-ray diffractometers that accommodate external electrochemical cells. Measurement geometry, sample-stage clearance, and mounting should be confirmed before use Potentiostat Compatibility Compatible with commercial three-electrode potentiostats for electrochemical control during operando XRD measurements Representative Application Example Operando XRD Tracking of LiCoO₂ Structural Evolution during OER A custom-designed three-electrode operando XRD/XAFS cell was used to track LiCoO₂ structural evolution during OER in 0.1 M KOH. As the potential increased stepwise from 1.1 to 1.7 V versus RHE, the LiCoO₂ (003) peak gradually weakened. New reflections at 12.87° and 25.88° appeared above 1.50 V, indicating K₀.₃CoO₂(H₂O)₀.₄ formation associated with potential-dependent cation intercalation and structural transformation. Demonstrated Operando XRD Capabilities Simultaneous XRD acquisition and electrochemical control Detection of potential-dependent crystalline phase transformations Correlation of diffraction evolution with applied electrode potential Application Studies Application studies using this model are currently underway. .
