In-situ/Operando Raman Battery Test Cell (2-electrode, compact titanium split cell) – REC 10

Compact operando Raman battery cycling cell for real-time material tracking

The REC 10 In-situ/Operando Raman Battery Test Cell (2-electrode) is a compact, sealed titanium split-cell designed for real-time Raman monitoring during battery charge–discharge. The cell compresses a two-electrode stack (working electrode vs counter electrode) separated by a user-supplied membrane/separator, enabling operando observation of phase transitions, surface film formation, and electrolyte decomposition pathways as the cell is cycled.

Working principle

A Raman microscope collects spectra through a dedicated optical window (Ø8 mm aperture) positioned close to the working electrode. The short optical path (working electrode to window <2 mm) improves sensitivity for surface and near-surface changes while the electrochemical response is driven by a battery cycler or potentiostat/galvanostat.

Key features and specifications

• High purity titanium body for broad chemical compatibility
• Cell body size: 50 × 50 × 20 mm (compact footprint)
• Optical window: Ø8 mm aperture; WE-to-window distance <2 mm
• O-ring sealed screw assembly to support leak minimisation and repeatable builds
• Spring-loaded compression to tune stack pressure and maintain stable contact
• Fast assembly/disassembly for cleaning and post-test sample recovery
  
  

Compatibility and applications

• Battery cyclers; potentiostats (two-terminal configuration)
• Operando Raman studies for lithium battery electrodes, SEI/CEI evolution, additive screening, and degradation analysis
• Glovebox assembly supported; cell can be transferred for measurement after assembly
