Spectroelectrochemical Cells
Spectroelectrochemical Cells, including in-situ Raman electrochemical cells, are powerful and specialized electrochemical devices that enable real-time, molecular-level such as Raman, UV-Vis and infrared (IR) spectroscopy investigation of electrode surfaces, interfaces, and electrolytes during the process of an electrochemical reaction. These cells feature transparent quartz windows for close laser access, with three-electrode configurations for precise control of potential and current. The three electrodes, working, reference and counter electrodes can be observed in the same chamber, or the reference electrode could be placed separately into different chambers in a H-cell.
Spectroelectrochemical cells find applications in battery and fuel cell research for the investigation of lithium-ion battery electrolyte decomposition, solid-electrolyte interphase (SEI) formation, and cathode structural changes. In situ Raman electrochemical cells show real-time studies of oxygen reduction reaction (ORR) intermediates. The gas diffusion In situ Raman electrochemical cell also finds applications in carbon dioxide reduction and hydrogen revolution reactions.

Troubleshooting Cyclic Voltammetry and Voltammograms
Cyclic voltammetry is a powerful and versatile electrochemical technique. With modern potentiostats and software packages, the method is relatively straight-forward to perform. Despite this apparent simplicity, there are still a number of things that can go wrong, particularly when setting up the electrochemical cell.
