The in-situ Raman electrochemical cell is mainly used to observe the in-situ spectral changes of electrode materials in electrochemical experiments, in order to explore the changes in the chemical structure of electrode materials during electrochemical reactions. This device is equipped with a reference electrode and a counter electrode, which can provide electrochemical experiments with a three electrode system and reserve a gas-liquid interface. It can be used for in-situ Raman spectroscopy of various high-temperature and gas/liquid cycles. The electrochemical cell can be quickly assembled and disassembled for easy cleaning.
