CNB-12-RM-3E
In-Situ Raman Battery Test Cell Model: RM-3E
RM-3E In-Situ Raman Battery Test Cell
A sealed three-electrode battery test cell with a lithium-wire reference electrode for in-situ Raman monitoring.
Product Overview
The RM-3E is a sealed three-electrode battery test cell integrating in-situ Raman measurement with electrochemical cycling. A spring-loaded lithium-wire reference electrode is connected to an independent middle current collector, forming a dedicated reference-electrode circuit for three-electrode testing. Its layered current-collector structure, adjustable spring compression, and O-ring sealing support stable electrode contact, reproducible assembly, and in-situ investigation of battery materials during charge/discharge cycling.
Key Features
• Lithium-Wire Reference Electrode
Spring-loaded contact connects the lithium wire to the middle current collector, establishing the reference-electrode circuit
• Adjustable Spring Loading
Allows the applied load to be adjusted for comparative evaluation under different compression conditions
• Glovebox-Compatible Sealing
The cell can be assembled in a glovebox and subsequently operated under ambient conditions with O-ring sealing

Published Application Example
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 RM-3E Capabilities
- 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
Application Studies
Additional application studies are underway.
