摘要
We report the growth of electrochemically deposited liquid lithium droplet in LiCl-KCl-Li2O melt at 673-723 K. To understand the transient behavior of liquid lithium in the electrolyte, the interface between the electro-deposited molten metal phase and the molten salt system was observed in situ using a high-speed digital microscope. We found that the droplets on the electrode are slightly flattened, when the colloidal Li content decreases due to an increasing Li2O content. This mechanism indicates that the heterogeneous distribution of the colloid Li may be due to the local Li solubility in the electrolyte.
