In Situ XRD Battery Test Cell (Two Electrode System) Model: XRD-2E

Description

Product Description

The XRD-2E is a sealed two-electrode battery test cell designed for in situ X-ray diffraction measurements during charge/discharge cycling. A low-background beryllium window provides direct X-ray access to the cell-stack, while the spring-loaded structure maintains stable interfacial contact. The high-purity titanium body, PEEK insulation, and chemically resistant O-ring sealing support repeatable assembly, glovebox preparation, and post-test sample recovery for rechargeable battery studies.

Key Features

• Bruker D8-Compatible XRD Measurement: Compatible with Bruker D8 X-ray diffractometer systems for operando XRD monitoring during battery cycling.
• Low-Angle XRD Accessibility: Supports XRD measurements from a minimum operating angle of 3°, enabling broader low-angle access for operando configurations.
• Spring-Loaded, Glovebox-Compatible Design: Maintains stable cell-stack compression and enables glovebox assembly with reliable O-ring sealing for subsequent operation under ambient conditions.

Note: Solid beryllium is relatively stable and poses low skin-contact risk; avoid inhaling dust or aerosols and wash hands after handling.

Instrument Compatibility

• XRD System Compatibility: Compatible with Bruker D8 systems and other X-ray diffractometers with suitable mounting and
  scan geometries. The sample holder, incident angle range, beam path, and instrument clearance should be verified before testing.
• Electrochemical Testing Compatibility: Compatible with commercial electrochemical workstations and battery testing systems that support two-electrode charge/discharge testing.

Related Published Application

Operando XRD Tracking of Conversion–Alloying Reactions: Alvi et al. used a Bruker D8 DISCOVER diffractometer with a Be-window operando cell to study SSBT-based anodes in lithium half-cells at C/5. Potential dependent XRD patterns revealed lattice expansion, transient Li₂Te formation, and reversible structural evolution during cycling.
