Description
Product Description
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.
Product 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.
Related Published Application
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.
