Uncontrolled dendrite growth in sodium (Na) metal anode demands that the stabilized Na to be implemented judiciously at a low cost beyond Lithium-ion technologies, such as room-temperature Na-S batteries. The realization of this goal requires an in-depth understanding of the complex interfaces between Na metal and electrolytes and the mechanism of the Na deposition/dissolution process. This work comprehensively studies the importance of the initial plating/stripping process on the working electrode by observing the voltage variations during cycling using 2- and 3-electrode cells. Using the 3-electrode cells, the asymmetry in plating and stripping potential and limitation of plated or stripped electrodes in cell failure have been identified. The changes in the electrode's impedances, morphology, and surface products have also been probed along with electrochemical signatures in different electrolytes. This effort to understand the notable metal growth and dissolution process leads to the cognizance of energy-dense metal-based batteries with safe operation.
