In-Situ Raman Pressure Battery Test Cell Model: RM-P2E

RM-P2E In-Situ Raman Pressure Battery Test Cell A sealed two-electrode cell for in-situ Raman monitoring during battery cycling under pressurized or vacuum conditions. Product Overview The RM-P2E is a sealed two-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 titanium cell body, PEEK insulation, and O-ring sealing provide chemical resistance and reliable airtightness. Designed for battery materials research, it supports real-time monitoring of structural and interfacial changes during charge/discharge testing at pressures up to 1 MPa. 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 • Pressure/Vacuum Operation Supports electrochemical cycling under controlled pressure or vacuum conditions with interchangeable gauges • Glovebox-Compatible Sealing Provides reliable airtight sealing for glovebox assembly and subsequent operation under ambient conditions Technical Specifications Electrode configuration Two-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 × H30 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 CH Instruments (CHI660E), and battery testing systems, including NEWARE (CT-4008T) Related Published Application In-situ Raman Tracking of Stepwise Polyiodide Conversion The cell used in this study, supplied by Beyond Battery under product code RM-2E, was coupled with a Renishaw inVia Raman microscope using 532 nm excitation and a CHI660E workstation to investigate KB–I₂ cathodes in aqueous Zn–I₂ batteries. During galvanostatic cycling, in-situ Raman spectra tracked I₃⁻ and I₅⁻ intermediates, revealing that ectoine promoted a stepwise I₅⁻ → I₃⁻ → I⁻ conversion pathway while suppressing polyiodide shuttling. Demonstrated Capabilities of the Base RM-2E Configuration Simultaneous Raman acquisition and galvanostatic cycling Real-time differentiation of I₃⁻ and I₅⁻ intermediates Electrolyte-dependent tracking of iodine conversion pathways Application Studies Application studies using this model are currently underway.
