Performance and Polarization Studies of the Magnesium–Antimony Liquid Metal Battery With the use of In-Situ Reference Electrode

This work presents the performance and polarization studies of a magnesium–antimony liquid metal battery with the use of an in-situ pseudo reference electrode at high operating temperature (ca. 700 °C). Due to the immiscibility of the contiguous salt and metal phases, the battery appears as three di...
