To directly observe and compare the morphology and stripping behavior of electrodeposited lithium and sodium films in buffered room-temperature molten salts.
Conducted in situ optical microscopy paired with electrochemical deposition and stripping tests at varying melt concentrations.
Tested lithium chloride and sodium chloride buffered chloroaluminate room-temperature molten salts using a tungsten working electrode.
Lithium electrodeposits exhibited dendritic, non-uniform growth on the tungsten electrode, leaving disconnected residual metal on the surface following discharge at moderate current densities.
Sodium electrodeposited as a smooth, uniform, flat film with little to no dendritic growth and stripped completely from the tungsten electrode without leaving disconnected metal residue.
