In-situ Raman Electrochemical Cell
In-situ Raman Electrochemical Cell, In-situ Raman Spectroscopy and Infrared Microscopes
Electrochemical cell designed for battery studies, electrocatalysis for CO2RR, HERs and fuel cells
In-situ Raman electrochemical cell is a compact design of an electrochemical cell to study the chemical and morphology changes on the surface of working electrode in real-time with Raman spectroscopy. The Raman laser is applied directly on the top of the electrochemical cell through a see-through optical window to detect the electrochemical changes as happened on the electrode. The in-situ Raman electrochemical cell typically adopts a three-electrode system with gas inlet/outlet, and an quartz window in the top of the cell body. Detecting instruments are typically confocal or surface enhanced Raman spectrometers, infrared microscopes, X-ray spectrometers. In-situ Raman electrochemical cell comes with three electrodes of platinum wire counter electrode, Ag/AgCl reference electrode and platinum sheet electrode holder for working electrode.

Key features of an in-situ Raman electrochemical cell
Integrated components: three electrodes including working, counter and reference electrodes, gas inlet/outlet, and a transparent optical window
Real-time analysis: While an electrochemical potential is applied to the working electrode, a laser from the Raman spectrometer is directed through the optical window to the working electrode surface.
Signal detection: As the electrochemical reaction occurs, the Raman spectroscopy provides information about the chemical species and structural changes happening at the interface.
In-situ Raman electrochemical cell finds versatile applications in battery studies to observe lithium-ion intercalation and deintercalation in graphite electrode, in electrocatalysis to study mechanisms for reactions like hydrogen evolution, oxygen reduction, and CO2 reduction, in corrosion research to monitor metal corrosion process, and in full cell development to investigate the electrochemical reactions occurring within fuel cells.
