N2 - A major issue during battery operation is hydrogen evolution (HE) at the negative electrode surfaces of Mg. However, during the current methods used for analyzing HE, the pH increases because of the HE reaction, which critically affects battery performance. Therefore, herein, a channel flow electrode system was applied in the in situ detection of hydrogen gas (HG) generated on Mg dissolution by gas chromatograph. This method enabled HG detection without an increase in pH upon Mg dissolution because electrochemical measurements could be performed under laminar flow. The HE efficiencies of Mg dissolution were thus estimated at various applied current densities.
