Summary: This study investigates how the plating/stripping behavior and solid electrolyte interphase (SEI) formation of calcium metal are influenced by changes in solvent composition in borohydride electrolytes. The results show that adding glymes to the electrolyte increases the plating overpotential and decreases the Coulombic efficiency of calcium plating/stripping. X-ray photoelectron spectroscopy reveals that an increase in glyme proportion leads to a higher relative abundance of organic C-O species and a decrease in borate species in the SEI.
