In-Situ Raman Pressure Battery Test Cell Model: RM-P3E

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 Combines interchangeable pressure or vacuum monitoring, adjustable spring loading, and airtight O-ring sealing for sealed battery testing Technical Specifications Electrode configuration Three-electrode system Sample-to-window distance < 2 mm Optical window diameter Ø20 mm Effective optical window diameter Ø12 mm Maximum pressure 1 MPa Optical window material Sapphire Cell body material Ti Insulation material PEEK Current collector tab Gold-plated copper Cell body dimensions Ø70 mm × H40 mm Instrument Compatibility • Raman System Compatibility Compatible with commercial Raman microscope systems, including Renishaw (inVia) and HORIBA (LabRAM Soleil Nano) • Electrochemical Testing Compatibility Compatible with commercial electrochemical workstations, including Bio-Logic (VSP-3E), and battery testing systems, including LAND (CT3004A) 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.
