RM-P3E In-Situ Raman Pressure Battery Test Cell

A sealed three-electrode cell for in-situ Raman monitoring during battery cycling under pressurized or vacuum conditions.

Product Overview

The RM-P3E is a sealed three-electrode battery test cell integrating in-situ Raman measurement with electrochemical cycling under controlled pressure or vacuum conditions. Its sapphire optical window and short sample-to-window distance facilitate Raman signal collection, while the three-electrode configuration enables working-electrode potential monitoring against a reference electrode. A high-purity titanium body, PEEK insulation, adjustable spring loading, O-ring sealing, and an integrated pressure gauge support reliable, glovebox-compatible testing under pressurized conditions. Vacuum operation is supported by replacing the pressure gauge with a compatible vacuum gauge.

Key Features

• In-situ Raman Monitoring
Enables real-time Raman characterization of electrode materials during battery charge/discharge operation

• Three-Electrode Configuration
Supports monitoring of the working-electrode potential against an independently connected reference electrode

• Pressure/Vacuum, Glovebox-Compatible Design

Related Published Application

In-situ Raman Tracking of Sodium Storage in Hard Carbon

The cell used in this study, supplied by Beyond Battery under product code RM-3E, was coupled with a HORIBA LabRAM Soleil Nano confocal Raman spectrometer to compare pristine T2 and Bi/N-modified T2-BiN hard-carbon anodes during sodium-ion battery cycling. In-situ spectra revealed a pronounced G-band redshift and reduced D-band intensity for T2-BiN, indicating enhanced Na⁺ intercalation-induced C–C bond strain and increased Na⁺ adsorption at defect sites.

Demonstrated Capabilities of the Base RM-3E Configuration

  • In-situ Raman monitoring during battery charge/discharge cycling
  • Comparative tracking of D- and G-band evolution
  • Identification of Na⁺ intercalation and defect-site adsorption
